INSTRUMENT DESCRIPTION1
1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
The models B05 (Supply and outputs unit) and P03S or P05S
(Display unit) are a digital controller system with microprocessor
that is typically used in cooling applications that have temperature
control with ON/OFF regulation and defrosting control at time
intervals, by arrival at temperature or by length of time of
continuous compressor operation through stopping the
compressor, electric heating or hot gas/cycle inversion.
The appliance has special defrosting optimisation functions and
functions to reduce the amount of energy used by the controlled
system.
The instrument has up to 4 relay outputs, up to 3 inputs
configurable for PTC, NTC and Pt1000 temperature probes or
digital inputs.
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 1

The 4 outputs can be used to control the compressor or the
temperature control device, the defroster, the evaporator fans and
a configurable auxiliary device (Light, Alarm, second evaporator,
etc.)
The 3 temperature probe inputs can be used to regulate cell
temperature, measure evaporator temperature, and measure
auxiliary temperatures (e.g. product temperature, condenser
temperature, etc.).
One digital input is always available on display unit P03 or P05
and, as an alternative to the Pr2 and Pr3 temperature probe inputs,
two other digital inputs can be configured.
The digital inputs can be configured to execute various functions
such as cell door signal, defrost commands, selecting a different
temperature-regulating set point, reporting an external alarm,
activating a continuous cycle, activating the auxiliary output, etc.
The sistem it can also be equipped with an internal buzzer for
acoustic notification of alarms and an alarm voltage function that
provides to disable the outputs if the mains voltage is too high or
too low.
The front of the operator panel is constituted by a large display (h
31 mm for the model P03S and 54 mm for the model P05S) 2
digits with sign -.
The programming of operating parameters is done by 4 capacitive
keys (S-Touch).
The connection between the two devices B05 and P03S or P05S is
via a three poles small cable that also provides power to the
operator panel.

2 - PROGRAMMING
2.1 - FAST PROGRAMMING OF SET POINT
Press the key P then release it and the display will show “SP” (or
“SE” or “SH”) alternating with the set value.
To change it press the UP key to increase the value or DOWN to
decrease it.
These keys increase or decrease the value one digit at a time, but
if the button is pressed for more than one second the value
increase or decreases rapidly, and after two seconds pressed, the
speed increases even more to all the desired valued to be reached
rapidly.
However, through par. "Ed” is possible to determine whether and
which Sets are set with the fast mode bybutton P.
The parameter is programmable with a value between oF and 4
which means that:
oF = Nothing is set with the key P (the P pressed and released
has no effect)
1 = can be adjusted only SP (normal)
2 = can be adjusted only SE (economic)
3 = can be adjusted both SP and SE
4 = can be adjusted the active set (SP or SE)
5 = can be adjusted SP and SH (“Turbo” or ind. “Heating”)
6 = can be adjusted SP, SE and SH
For example, if the parameter "Ed" = 1 or 3, the procedure is as
follows:
Press key P then release it and the display will show "SP"
alternate value.
To modify press key UP or DOWN to increase the value to
decrease.
If there is only the Set Point 1 ("Ed" = 1) once the desired value by
pressing the P button to exit the Set programming mode.
If is also programmable the EconomicSet Point ("Ed" = 3) by
pressing and releasing the P key again the display will show "SE"
alternate to the set value.
To modify press key UP or DOWN like Set “SP”.
When the desired value is set press the key P to exit from Set
Point programming mode.
Exiting the Set mode is achieved by pressing the P key or
automatically if no key is pressed for 10 seconds. After that time
the display returns to the normal function mode.
2.2 - STANDARD MODE PARAMETERS PROGRAMMING
To access the instrument’s function parameters when password
protection is disable, press the key Pand keep it pressed for about
5 seconds, after which the display will visualised the code that
identifies the first group of parameters (“ -SP “).
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 2

Using the UP and DOWN keys, the desired group of parameters
can be selected and pressing the P key, the display will show the
first parameter code of the group.
Using the UP and DOWN keys, the desired parameter can be
selected and pressing the P key, the display will alternately show
the parameter code and its setting that can be changed with the UP
and DOWN keys.
Once the desired value has been set, press the key P again: the
new value will be memorised and the display will show only the
code of the selected parameter.
Pressing the UP and DOWN keys, it is possible to select another
parameter and change it as described.
To come back at the group selection mode keep the U key pressed
for 1 sec. until will show the code group.
Pressing the UP and DOWN keys, it is possible to select another
group of parameters, another parameter and change it as
described.
To exit the programming mode, do not press any key for about 30
seconds, or keep the U key pressed for 2 sec. until it exits the
programming mode.

- notes: in the parameters in which the variable is a time value is
displayed with the - sign for the least significant part (eg. seconds
or minutes), while the most significant (minutes or hours) is shown
with a positive value.
2.3 - PARAMETER PROTECTION USING THE PASSWORD
The instrument has a parameter protection function using a
password that can be personalised, through the “PP” parameter.
If one wishes to have this protection, set the password number
desired in the parameter “PP”. When the protection is activate,
press the P key to access the parameters and keep it press for
about 5 seconds, after which the display will show “r.P” .
At this point press P, the display show “0”, using the UP and
DOWN keys, set the password number programmed and press
the key P.
If the password is correct, the display will visualise the code that
identifies the first group of parameters and it will be possible to
program the instrument in the same ways described in the previous
section.
Protection using a password can be disabled by setting the
parameter “PP” = oF.
2 sec.
Hold for
5 sec.
Hold for
Note: If the Password gets lost, just swith off and on the instrument
supply, push P key during the initial test and keeping the key
pressed for 5 seconds.
In this way it’s possible to have access to all the parameters, verify
and modify the par. “PP”.
2.4 - CUSTOMIZED MODE PARAMETER PROGRAMMING
(PARAMETERS PROGRAMMING LEVEL)
The password protection hides all the configuration parameters
behind a factory set password to avoid unwanted changes being
made to the programming of the controller.
To make a parameter accessible without having to enter the
password when “PP” password protection is activate follows this
procedure.
Enter the programming using the Password “PP” and select the
parameter which is desired to be accessible with no password
protection.
Once the parameter has been selected, if the SET led is blinking,
this means that the parameter is programmable by entering the
password (it’s then “protected”) if it’s instead on, this means the
parameter is programmable without password (not protected).
If you want to change the accessibility of the parameter push P
key, keep it pressed and press together also the key UP.
The led SET will change its state indicating the new access level of
the parameter (on = not protected; blinking = protected by
password).
5 sec.
Hold for
2 sec.
Hold for
In case some parameters are not protected, when one tries to have
access at the programming, the display will show all the
parameters not protected and the par. “r.P” (through which will be
possible to have access to the “protected” parameters.)
2.5 - RESET PARAMETERS TO DEFAULT VALUE/LEVEL
The instrument allows the reset of the parameters to values
programmed in factory as default.
To restore to the values of default the parameters set the value -48
to “r.P” password request.
Once confirmed the password with the key P the display it shows
"---" for 2 sec. therefore the instrument effects the parameters
reset..
2.6 - KEYBOARD LOCK FUNCTION
On the instrument it’s possibile to lock completely the keyboard.
This function is particularly useful when the regulator is reachable
by the users and it’s desired to avoid any modification.
To activate the keyboard lock it’s enough program the par. “Lo” to
a different value to oF.
The value program to this parameter it is the time of inactivity of the
keys afterwhich the keyboard will be locked.
Insofar not pressing any key for the time "t.Lo" the instrument
automatically disable the normal functions of the keys.
When the keyboard is lock, if any of the key is pushed, on the
display will appear “Ln” to indicate the active lock.
To unlock the keyboard it’s enough to contemporarily push key P
and UP and keep them pushed for 5 sec., afterwhich the label “LF”
will appear on the display and all the keys functions will be availab-
le again.
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 3

3 - INFORMATION ON INSTALLATION AND USE
3.1 - PERMITTED USE
The instrument has been projected and
manufactured as a measuring and control device to
be used according to EN60730-1 for the altitudes
operation until 2000 ms. The use of the instrument
for applications not expressly permitted by the
above mentioned rule must adopt all the necessary protective
measures.
The instrument CANNOT be used in dangerous environments
(flammable or explosive) without adequate protection.
The instrument used with NTC 103AT11 probe (identifiable by the
printed code “103AT-11” visible on the sensor part) or Pt1000 is
compliant with standard EN 13485 ("Thermometers for measuring
the air and product temperature for the transport,storage and
distribution of chilled, frozen, deep-frozen/quick-frozen food and ice
cream”) with the following classification: [EN13485 air, S, A, 1,-
50°C +90°C]
Remember that the end user must periodically checks and verify
the thermometers in compliance with standard EN 13486.
The installer must ensure that EMC rules are respected, also after
the instrument installation, if necessary using proper filters.
Whenever a failure or a malfunction of the device may cause
dangerous situations for persons, thing or animals, please
remember that the plant has to be equipped with additional devices
which will guarantee safety.
3.2 - MECHANICAL MOUNTING
The B05 unit is designed for mounting inside enclosure by 2
screws.
The instrument P03S, in case 96 x 50 mm, and P05S, in case 135
x 97 mm is designed for flush-in panel mounting. Make a hole 90 x
44 mm (P03S) or 124 x 85 mm (P05S) and insert the instrument,
fixing it with the provided special brackets.
We recommend that the gasket is mounted in order to obtain the
front protection degree as declared.
Avoid placing the B05 unit and internal side of P03S or P05S in
environments with very high humidity levels or dirt that may create
condensation or introduction of conductive substances into the
instrument. Ensure adequate ventilation to the instruments and
avoid installation in containers that house devices which may
overheat or which may cause the instrument to function at a higher
temperature than the one permitted and declared. Connect the
instruments as far away as possible from sources of
electromagnetic disturbances such as motors, power relays, relays,
solenoid valves, etc.
3.3 - ELECTRICAL CONNECTION
Carry out the electrical wiring by connecting only one wire to each
terminal, according to the following diagram, checking that the
power supply is the same as that indicated on the instrument and
that the load current absorption is no higher than the maximum
electricity current permitted. As the instrument is built-in equipment
with permanent connection inside housing, it is not equipped with
either switches or internal devices to protect against overload of
current: the installation will include an overload protection and a
two-phase circuit-breaker, placed as near as possible to the
instrument, and located in a position that can easily be reached by
the user and marked as instrument disconnecting device which
interrupts the power supply to the equipment. It is also
recommended that the supply of all the electrical circuits connected
to the instrument must be protect properly, using devices (ex.
fuses) proportionate to the circulating currents. It is strongly
recommended that cables with proper insulation, according to the
working voltages and temperatures, be used. Furthermore, the
input cable of the probe has to be kept separate from line voltage
wiring. If the input cable of the probe is screened, it has to be
connected to the ground with only one side. We recommend that a
check should be made that the parameters are those desired and
that the application functions correctly before connecting the
outputs to the actuators so as to avoid malfunctioning that may
cause irregularities in the plant that could cause damage to people,
things or animals.

4 - FUNCTIONS
4.1 - ON / STAND-BY FUNCTION
The instrument, once powered up, can assume 2 different
conditions:
- ON : means that the controller uses the control functions.
- STAND-BY : means that the controller does not use any control
function and the display is turned off except for the Stand-by led.
If there is no power, and then power returns, the system always
sets itself in the condition it was in before the black-out.
The ON/Stand-by function can be selected:
- Pressing the key U for at least 1 sec. if the parameter "UF" = 3 or
5
-Pressing the key DOWN/AUX for at least 1 sec. if the parameter
"Fb" = 3 or 5
- using the digital input if the parameter “xF” = 7 or 15
4.2 - "NORMAL", "ECONOMICAL" AND "TURBO" OPERATING
MODES
The instrument can be used to enter up to 3 different regulating set
points: Normal - “SP”; Economical - “SE”; and “Turbo” - “SH”.
Associated with each of these is the corresponding differential
(hysteresis): normal - “d”; Economical - “Ed”; and “Turbo” - “Hd”.
Switching between the various modes can be automatic or manual
"NORMAL-ECONOMICAL" MODE OPERATION
Can be used where it is necessary to switch between two different
operating temperatures (e.g. day/night or working days/holidays)
NORMAL/ECONOMICAL mode can be selected manually:
– by pressing the U key if parameter "UF" = 2
– by pressing the DOWN/AUX key if parameter "Fb" = 2
– by a digital input if parameter “xF” = 6
NORMAL/ECONOMICAL mode can be selected automatically:
– after the door has been closed for time “Et” (switching from
Norm. to Eco)
– when the door is opened if the SE set point is active from
parameter “Et” (switching from Eco to Norm.)
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 4

Example of automatic switching between Eco mode and normal
mode. During working hours the door is frequently opened and the
controller stays in normal mode. When the door has not been
opened for time “Et”, the controller switches to Eco mode. As soon
as the door is opened again, the controller reverts to normal mode.
This function requires use of a digital input configured as “xF” = 1,
2 or 3 (door open input)
If “Et” = oF, selection of Eco/Norm. mode via the digital input
configured as door, is deactivated.
If “tt” = oF, switching the mode from Eco to Normal due to time-out
is deactivated.

(2) – The time tt stops when the door is opened and the instrument
immediately switches to "normal" mode. In the case shown, the
door is always closed.
When in economical mode, the label “Ec” is displayed.
If “dS”= Ec, in economical mode the instrument displays “Ec” all the
time. Otherwise the label "Ec" appears approx. every 10 seconds
alternating with the normal display set by the “dS” parameter.
Selection of Eco mode is always also combined with the function of
turning off the Auxiliary output if used as a window light (“Fo”= 3).
"TURBO – NORMAL – ECONOMICAL" MODE OPERATION
"Turbo" mode can be selected manually:
– by pressing the U key if parameter "UF" = 4
– by pressing the DOWN/AUX key if parameter "Fb" = 4
– by a digital input if parameter “xF” = 8
"Turbo" mode can be selected automatically:
- on leaving Eco mode (only if “HC” = C3)
- every time the instrument is switched on (only if “HC” = C3 and
Pr1 > SE+Ed)
The instrument quits "turbo" mode automatically at the end of time
“tC” or manually using the programmed command (key or digital
input) and the instrument always returns to normal mode.
"Turbo" mode can be applied manually, for example when the user
wishes to lower the temperature of the products quickly after
loading the refrigerator.
However, "Turbo" mode is applied automatically to restore product
temperature at the end of economical mode.

case shown the door is always closed.
(2) – The time tt stops when the door is opened and the instrument
immediately switches to "Turbo" mode. In the case shown, the door
is always closed.
When switched on, the instrument starts in normal mode unless
the temperature at switch-on is > SE+Ed. In this case (see fig.) a
"Turbo" cycle is automatically initiated.
After time “tC” the instrument automatically enters "Normal" mode.
If the door is opened frequently the instrument stays in "Normal"
mode. If however it is not opened for time “Et” it automatically
switches to "Eco" mode.
The instrument remains in "Eco" mode until the door is opened
again or, if set, until the time-out “tt”.
On leaving "Eco" mode the instrument therefore runs a "Turbo"
cycle to allow product temperature to be restored, after which it
reverts to "Normal" mode and so on.
When “turbo” mode is on, this is indicated by the characters “tb”
shown on the display, alternating with the normal display.
The Set point "SP" can be set with a value between the
programmed value in parameter. “LS” and the programmed value
in parameter “HS”.
The Set point "SE" can be set with a value between the
programmed value in parameter. “SP” and the programmed value
in parameter “HS”.
The Set point "SH" can be set with a value between the
programmed value in parameter. “LS” and the programmed value
in parameter “SP”.
Note: in the examples that follow, the Set point is generally
indicated as "SP" and the histeresis as “d”, how when operating the
instrument will work according to the Set point and histeresis
selected as actives.
4.3 - MEASURING AND DISPLAY
All the parameters concerning measuring are contained in the
group “-In”.
Via the parameter “St” it is possible to select the type of probes
that one wishes to use and which can be: thermistores PTC
KTY81-121 (Pt), NTC 103AT-2 (nt) or Pt1000 (P1).
Via the parameter “uP”, it is possible to select the temperature
unit of measurement the desired measurement resolution (C0=°C /
1°; C1=°C / 0.1°; F0= °F / 1°; F1= °F / 0.1°).
The instrument allows the measuring to be calibrated, that can be
used for re-calibrating the instrument according to application
needs, through the parameters “C1” (for the input Pr1),“C2” (for
the input Pr2) ,“C3” (for the input Pr3).
The functions carried out by Pr2, Pr3 probes is defined by the
parameters “i.P2”, “i.P3”.
This parameters can be configured for the following functions:
= EP - Evaporator probe: used to managing the defrost and the
evaporator fans (see relative functions)
= Au - Auxiliary Probe: can be used as a display-only probe but it is
also possible to assign temperature alarms to it (possible uses:
product probe, anti-freeze probe, etc.)
= cd - Condenser Probe: can be used as a display-only probe but it
is also possible to assign temperature alarms to it in order to give
alarms relating to condenser malfunction (e.g. dirty/clogged
condenser).
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 5

= dG - Digital input (see digital inputs functions)
If probe Pr2 and/or Pr3 is/are not used, set the relative parameter
“P2”and/or “P3” = oF.
It is not possible to program more parameters for the same function
(priority goes to lowest input).
Using the parameter “Ft”, it is possible to set the time constant for
the software filter for measuring the input values to be able to
reduce the sensitivity to measurement disturbances (increasing the
time).
In addition to this filter are present two other similar filters but used
only for the display of the temperature Pr1 both as regards the in-
crease (par. "du") that the decrease (par. "dd") of the measure to
avoid display a rapid temperature change.
The filter blocks the decrease in maximum display to 0.1 °each
"dd" sec. and increase the maximum display each "du" sec ..
Every switch-on the filters are reset.
To see the temperature Pr1 filtered set par. "dS" = F1
Through the parameter “dS”, it is possible to fix the normal
visualisation on the display that can be the measurement of the
probe Pr1 (P1), the measurement of the probe Pr2 (P2), the
measurement of the probe Pr3 (P3), the active set point value (SP),
the label “Eco” when the instrument is in Eco mode (Ec) or it can
have the numerical display switched off (oF).
Through the parameter “CU”, it is possible to program an measure
offset that will be applied to the temperature show on the display
(only if dS”= P1, P2, P3, Ec, F1).
The normal visualisation on the display is established by par. “dS”,
but it is possible to visualise all the variables and the highest and
lowest Pr1 peak measurement values in rotation by quickly
pressing and releasing key U.
The display will alternately show the code that identifies the
variable and its value.
The variable are:
“P1” - Pr1 temperature
“P2” - Pr2 temperature ( on/oF state if is progr. as digital input )
“P3” - Pr3 temperature ( on/oF state if is progr. as digital input )
“Lt” and the lowest Pr1 peak temperature
“Ht” and the highest Pr1 peak temperature
If the main voltage alarms are activated in this mode will be
displayed the variable P5 that represents the main voltage with a
value decreased of 150 V.
The main voltage tension measured by the instrument will be
therefore V = P5 + 150.
If the voltage measure is not correct it is possible to modify it
through the par. "OU".
When the instrument is switched off, peak values are always
re-set. However, it is also possible to reset these values if the
instrument is switched on by using the DOWN key hold for 3 sec.
during peak visualization.
The display will show “---” and peak memory will be reset.
The exit of this visualisation mode occurs automatically 15 seconds
after the last pressing on the key U.
Please remember that visualisation of the Pr1 probe can be
changed by the defrosting display lock function, by using the
parameter “dL” (see defrost function).
4.4 - DIGITAL INPUTS
All the parameters concerning digital inputs are contained in the
group “-In”.
The instrument P03S / P05S
has 1 digital input for voltage free contacts whose function is
defined by the parameters “1F” and and whose action can be
delayed by the time period set in the parameter “1t”.
In addition, the instrument may have 2 further digital inputs for
voltage-free contacts as an alternative to the measurement inputs
Pr2 and Pr3.
In order to use these inputs digitally, the user must set the relevant
parameter “P2” or “P3” = dG.
The function performed by these digitally configured inputs is
defined by the parameters “2F” and “3F”
The Pr2 digital input action can be delayed by the time period set in
the parameter “2t” while the action of Pr3 digital input is instanta-
neous and cannot be delayed.
The parameters “i.1F” , “i.2F”, “i.3F” can be configured for the
following functions:
= 0 - No function
= 1 -Cell door opening by contact normally open: on closing the
digital input the instrument visualises oP and the variable set in
parameter “dS” alternately on the display. With this function mode,
the action of the digital input also activates the time that can be set
in parameter "oA" after which the alarm is activated to signal that
the door has been left open.
= 2 -Cell door opening with fan stop by contact normally open: on
closing the digital input the fans are stopped and the instrument
visualises oP and the variable set in parameter “dS” alternately on
the display. With this function mode, the action of the digital input
also activates the time that can be set in parameter "oA" after
which the alarm is activated to signal that the door has been left
open and the fan restart.
= 3 - Cell door opening with compressor and fan stop by contact
normally open: similar to “i.x” = 5 but with fan and compressor stop.
At the intervention of the door open alarm alarm compressor and
fan restarts.
= 4 - External alarm signal by contact normally open: on closing
the digital input the alarm is activated and the instrument visualises
AL and the variable set in parameter “dS” alternately on the
display.
= 5 - Signalling of external alarm with disablement of all the control
outputs by contact normally open: on closing the digital input all
the control outputs are disabled, the alarm is activated and the
instrument visualises AL and the variable set in parameter “dS”
alternately on the display.
= 6 - Selecting the active set point (SP/SE) with contact normally
open: on closing the digital input the temperature set point “SE” is
activated. When instead the input is open the set point “SP” is
active.
= 7 - Switching on/switching off (Stand-by) of instrument by contact
normally open: on closing the digital input the instrument is
switched on while it is placed in Stand-by when opened.
= 8 - "Turbo" cycle activation command with normally-open contact:
closing the input starts a "turbo" cycle.
= 9 - Remote command of auxiliary output AUX with normally-open
contact: closing the input activates the auxiliary output as
described in the "Fo" = 2 operating mode of the auxiliary output.
= 10 - Not used
= 11 - Not used
= 12 - External "Pr" alarm notified and "ot" output deactivated by
normally-open contact: closing the input deactivates the output
configured as "ot" and activates the alarm, and the instrument
display shows Pr alternating with the variable defined by the “dS”
parameter.
= 13 - External “HP” alarm notified and “ot” output deactivated by
normally-open contact: closing the input deactivates the output
configured as “ot” and activates the alarm, and the instrument
display shows HP alternating with the variable defined by the “dS”
parameter.
= 14 - External “LP” alarm notified and “ot” output deactivated by
normally-open contact: closing the input deactivates the output
configured as “ot” and activates the alarm, and the instrument
display shows LP alternating with the variable defined by the “dS”
parameter.
= -1, -2, -3, etc. - Like function with positive values but with
function logic reversed (contact normally closed)
Note: Where multiple digital inputs are configured for the same
function, the instrument will treat the contacts as if they were
parallel (and consequently regard the result as an OR function).
4.5 - OUTPUTS AND BUZZER CONFIGURATION
All the parameters concerning outputs configuration are contained
in the group “-Ou”.
The instrument outputs can be configured by the relative
parameters “o1” , “o2”, “o3”, “o4”.
The outputs can be configured for the following functions:
= ot - to control the compressor or however, the temperature
control device
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 6

= dF - to control the defrosting device
= Fn - to control the evaporator fans
= Au - to control the auxiliary device
= At - to control a silenceable alarm device through a contact that
is normally open, and then closed when the alarm sounds
= AL - to control an alarm that cannot be silenced through a
contact that is normally open and closed when the alarm sounds.
= An - to control an alarm with a memory function through a
contact that is normally open and closed when the alarm sounds.
= -t - to control a silenceable alarm device through a contact that is
normally closed, and then open when the alarm sounds.
= -L - control an alarm that cannot be silenced through a contact
that is normally closed and open when the alarm sounds.
= -n - to control an alarm with a memory function through a contact
that is normally closed and open when the alarm sounds.
= on - Output on when the instrument is in on state. This mode can
be used to control lights, non-misting resistance on room door or
other utilities
= HE - to control an heating device in neutral zone control mode
(“r.HC” = nr).
= L1 - Light output managed by Normal / Economy mode.
This output will be on in Normal mode and off in Economy mode
operation.
= L2 - Internal Light output managed by digital input. This output
will be on when door is opened (only if “xF”= 1, 2, 3).
= oF - Disabled output
The function carried out for auxiliary output (par. desired output =
Au) is defined by the parameter “Fo” and the function is
conditioned by the time set in parameter “tu”.
The parameter “Fo” can be configured for the following functions:
= oF - Auxiliary output not active
= 1 - Temperature control output delayed with contact normally
open: the auxiliary output is activated with delay that can be set on
the parameter "tu" compared to the output configured as ot. The
output is then turned off at the same time as the ot output is
disabled. This function mode can be used as a command for a
second compressor or for all other working utilities according to the
same ot output conditions, but which must be delayed after the
start up of the compressor to avoid excess electricity absorption.
= 2 - Activation by front key (U or DOWN/AUX) or by digital input :
the output is activated by pressing the keys U or DOWN/AUX
suitably configured (“UF” or “Fb” = 1), by a digital input suitably
configured (“xF” = 9). The commands by keys or digital inputs have
a bi-stable function. Which means that when first pressed, the
output is activated while the second is disabled. In this mode, the
AUX output can be turned off automatically after a certain time that
can be set on the parameter "tu". With "tu" = oF the output is
activated and deactivated only manually, using the key (U or
DOWN/AUX). Differently, the output, once activated, is turned off
automatically after the set time. This function can be used, for
example, as a cell light command, for non-misting resistance or
other utilities.
The internal buzzer (if present) can be configured by par. “bu” for
the following functions:
oF = Buzzer always disable
1= Buzzer signal active alarms only
2= Buzzer signal key pressed only (no alarm)
3= Buzzer signal active alarms and key pressed
4= Buzzer signal active alarms (with intermittent beep) and key
pressed
4.6 - TEMPERATURE CONTROL
Most of the parameters for temperature control functions are found
in the “-rE” group.
The instrument's method of regulation is of ON/OFF type acting on
the "ot"- and "HE"-configured outputs in response to: the reading of
the Pr1 probe; the active set point(s) “SP” (or “SE” and/or “SH”);
the intervention differential “d” (or “Ed” and/or “Hd”); and the
operating mode “HC”.
Via the parameter “HC” the following functions can be obtained:
= C (Cooling) or = H (Heating)
As regards the operating mode programmed in the "HC"
parameter, the regulator automatically assumes that the differential
has positive values for a Refrigeration control (“HC”=C), negative
values for the Heating control (“HC”=H).

If the parameter “HC” is programmed such that “HC” = nr the output
configured as “ot” operates with a cooling action (as “HC” = C)
whereas the output configured as “HE” operates with a heating
action. In this case the regulating set point for both outputs is
whichever of SP, SE and SH is active, and the intervention
differential (“d” or “Ed” or “Hd”) is automatically assumed by the
regulator to have positive values for the cooling action, negative
values for the heating action.

Similarly, if the parameter “HC” is programmed such that “HC” =

“HC” = C) whereas the output configured as “HE” operates with a
heating action.
In this case the regulating set point for the "ot" output is whichever
of SP, SE and SH is active, whereas for the output "HE" the set
point is SH.
The intervention differential for the “ot” output will be whichever is
active (“d” or “Ed” or “Hd”) and the regulator will automatically
assume it has positive values (in the case of Cooling) whereas for
the output "HE" it will be "Hd" with values assumed to be negative
(in the case of Heating).
In this mode, activating the "turbo" cycle causes the instrument to
operate with neutral-zone regulation with set point SH.

ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 7

All time protections described in the next paragraph (P1, P2, P3)
always act only on the output configured as “ot”.
In the event of probe error, it is possible to set the instrument so
that that the output “ot”continues to work in cycles according to the
times programmed in the parameter “t1” (activation time) and “t2”
(deactivation time). If an error occurs on the probe the instrument
activates the output for the time “t1”, then deactivates it for the time
“t2” and so on whilst the error remains. Programming “t1” = oF the
output in probe error condition will remain switched off.
Programming instead “t1” to any value and “t2” = oF the output in
probe error condition will remain switched on.
Remember that the temperature regulation function can be
conditioned by the “Compressor Protection and output delay at
power-on”, “Defrost”, “Door open” and “external alarm with outputs
disable” functions.
4.7 - COMPRESSOR PROTECTION FUNCTION AND DELAY AT
POWER-ON
All the parameters concerning compressor protection functions are
contained in the group “-Pr”.
The function “Compressor Protection” aims to avoid close start ups
of the compressor controlled by the instrument in cooling
applications.
This function foresees 3 time controls on the switching on of the
output configured as “ot” associated with the temperature
regulation request.
The protection consists of preventing the output being switched on
during the times set in the parameters “P1”, “P2” and “P3” and
therefore that any activation occurs only after all the times has
finished.
First control (par. “P1” ) foresees a delay to the output “ot”
activation (switching-on delay).

instrument is turned on, for the time set in the parameter “od”.

All the functions are disabled by relative parameters = oF.
4.8 - DEFROST CONTROL
The defrosting control acts on the outputs configured as “ot” and
“dF”.
All the parameters concerning defrost control are contained in the
group “-dF”.
The type of defrosting that the instrument must carry out is set by
the parameter “dt” that can be programmed:
= EL - WITH ELECTRICAL HEATING (or BY STOPPING
COMPRESSOR): during defrosting, the output “ot” is deactivated
while the output “dF” is enabled.
The defrost will be by Stopping compressor if not using the “dF”
output
= in - WITH HOT GAS or INVERSION OF CYCLE:
during defrosting the outputs “ot” and “dF” are enabled
= no - WITHOUT COMPRESSOR OUTPUT CONDITIONING:
during defrosting, the output “ot” continuous to operate in order to
temperature controller while the output “dF” is enabled.
= Et - WITH ELECTRICAL HEATING AND DEFROSTING
TEMPERATURE CONTROL: during defrosting, the output “ot” is
deactivated while the output “dF” operate as evaporator
temperature control. In this mode the defrost lenght is by time-out
(time "dE"). During the defrost "dF" output it behaves as an
heating mode temperature control with Set = "tE" and fixed
differential at 1°C and operate in order to evaporator probe (EP).
4.8.1 - STARTING AUTOMATIC DEFROSTS
The automatic control of defrost occours:
- By interval times (regular or dynamic)
- By Evaporator temperature
- By continuous compressor running time
In order to avoid pointless defrosting the parameter “tS” in “dC” =
rt, ct, cS mode is foreseen that sets the enablement temperature
for defrosting
If the temperature measured by the probe is higher than set in the
parameter “tS” the defrosting is inhibited.
- Defrost by regular interval time
Counting mode interval and automatic defrost starts is set through
the parameter "dC" that can be programmed:
= rt - intervals with counts the total function time (instrument on)
This mode results that currently used in the refrigerators systems.
= ct - intervals with counts only the compressor function time
(output “ot” switched on)
Mode typically used in the positive temperature refrigerators
system with defrost by stopping compressor.
= cS - the instrument carries out a defrosting cycle at each
compressor stop (i.e. at each deactivation of the output “ot”) or
however at defrost interval end with counts the total function time
(instrument on).
If "di" = oF the defrost happens only to the compressor stop.
This mode is used only on particular refrigerator system in which is
desired to always have the evaporator to the maximum efficiency
conditions every compressor cycle.
The automatic defrost function is activate when at the parameter
“di” is set the defrost interval time.
The first defrost after swiching on can be set by par. “Sd”
This allows to perform the first defrost to a different interval from
"di." time.
If it is desired that to every instrument power on a defrost cycle is
realized (as long as the conditions set in the parameters “tS” and
"tE" apply) program the par. "Sd" = oF.
This allows the evaporator to be permanently defrosted, even when
frequent interruptions to power supply occur that may cause the
cancellation of the various defrosting cycles.
Instead if is desired all defrost to the same interval program "Sd" =
"di."
Automatic defrost function by interval is disable when “di” = oF.
“Dynamic Defrost Intervals System”.
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 8

If “dd” = 0 the Dynamic defrost is disable.
Note: For this function is necessary to use the evaporator probe,
program “dC” = rt, ct or cS and set “d.dd” = any value (not 0)
This mode allows to dynamically reduce in progress the defrost
interval counting ("di" or "Sd" if is the first defrost), anticipating so
the execution of a defrost when it was necessary, in order to an
algorithm that allows to notice a decrease performances of
refrigerator thermal exchange.
Besides it maintains activates the defrost by evaporator temperatu-
re mode that it allows a further possibility of control of the defrost in
order to notice a decrease performances of refrigerator thermal
exchange.
The algorithm allows to esteem a reduction of thermal exchange in
base to the increase of the difference of temperature between Pr1
(controlled temperature) and evaporator (“EP” probe) that is memo-
rized by the instrument in proximity of the Set Point.
The advantage of the “Dynamic Defrost Interval” is the possibility to
program a defrost interval time more longer than normal.
The instrument will have the possibility to anticipate the defrost if
necessary or to start the cycle after the programmed time.
If the system results set correctly is possible to to avoid many non
necessary defrosting cycles (and therefore to obtain an energy sa-
ving) that could instead happens in the normal operation when, to
guarantee with greater certainty the system efficency , the defrost
interval is programmed at a too low time.
By par.: “d.dd” - DEFROST INTERVAL PERCENTAGE
REDUCTION is possible to establish the percentage of reduction of
the remaining time to start defrost when the conditions for the
reduction happen.
If par. "dd" = 100% at the first increase of the memorized difference
of temperature between cell (Pr1) and evaporator (> 1 °) a defrost
start immediately
For correct functioning the instrument needs a first reference value
of the temperature difference between cell and evaporator.
Every variation of the value of the Active Set Point, of the
differential "d", the start of a continuous cycle or the a defrost
execution delete this reference value and any reduction will be
performed until the acquisition of a new reference value.

Example “dynamic defrost intervals system” with a reduction “dd” =

- Defrost by evaporator temperature
The instrument starts a defrost cycle when the evaporator
temperature (“EP” probe) goes below the “tF” programmed
temperature for “St” programmed time.
This system can be used in heat pump defrost system (in this case
the defrosting intervals are usually disabled) or to guarantee a
defrost if the evaporator reaches very low temperatures that
normally result symptomatic of a bad thermal exchange in
comparison to the normal working conditions.
If “tF” = -99.9 the function is disable.
- Defrost by continuous compressor running time
The instrument start a defrost cycle when the compressor is turned
on continuously for the time "cd”.
This function is used because the continuous operation of the com-
pressor for an extended period is usually symptomatic of a bad
thermal exchange in comparison to the normal working conditions.
If "cd" = oF the function is disabled.
4.8.2 - MANUAL DEFROST
To start up a manual defrosting cycle, press the key UP/DEFROST
when it is not in programming mode and keep it pressed for about
5 seconds after which, if the conditions are correct, the led Defrost
will light up and the instrument will carry out a defrosting cycle.
To stop a defrosting cycle, press the key UP/DEFROST during a
defrost cycle and keep it pressed for about 5 sec.
4.8.3 -DEFROST ENDS
The automatic defrosting cycle can be ended by time or, if an
evaporator probe is used (“EP” probe), when a temperature on the
evaporator is reached.
If the evaporator probe is not used the duration cycle is set by the
parameter “dE”.
If instead the evaporator probe is used the defrost cycle end when
the temperature measured by the evaporator probe exceeds the
temperature set in the parameter “tE”.
If this temperature is not reached in the time set in the parameter
“dE”, defrosting is interrupted.
If the temperature measured by the probe is higher than the
temperature set in the parameter "tS" and “tE” the defrosting is
inhibited.

Example of electric defrost with evaporator temperature control:

“dF” output switch on/off to control evaporator temperature in
heating mode with set point “tE” and 1°differential (Hysteresis).
The active defrost is shown on the instrument display with the
lighting up of the DEFROST led
At the end of defrosting, it is possible to delay the new start up of
the compressor (output “ot”) at the time set in parameter “td” to
allow the evaporator to drain.
During this delay, the led Defrost flashes to indicate the draining
state.
4.8.4 - DEFROSTS IN EVENT OF EVAPORATOR PROBE
ERROR
In event of evaporator probe error the defrosts occur at intervals
"Ei" and duration "EE”.
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 9

In case an error occurs when the time remaining to the start or the
end of defrost it’s lower than that normally set the parameters
related to error conditions probe, the start or the end take place
with the shortest time.
The functions are provided because when the evaporator probe is
used the defrost endurance time is usually set longer than
necessary (the time “dE” is a security time-out) and in case is used
the "Dynamic Intervals Defrost System” the interval is usually set
more longer than what is normally programmed into instruments
that do not have the function.
4.8.5 - DEFROST DISPLAY LOCK
Through par. “dL” and “dA” it’s possible to define the display
behaviour during defrost.
The “dL” parameter pemits the display visualization lock on the last
Pr1 emperature reading (“dL” = on) during all the defrost cycle until,
at the end of defrost, the temperature has not reached the lock
value or the value [”SP” + “d”] or is elapsed the time setted on par.
"dA".
Or it permits only the visualization of label “dF” (“dL” = Lb) during
the defrost cycle and, after the defrost, of label “Pd” until, at the
end of defrost, the Pr1 temperature has not reached the lock value
or the value [”SP” + “d”] or is elapsed the time setted on par. "dA".
The display will otherwise (“dL”= oF) continue to visualize the Pr1
temperature measured by the probe during the defrost cycle.
4.9 - EVAPORATOR FANS CONTROL
All the parameters concerning fans control are contained in the
group “-Fn”.
The control of the fans on the output configured as “Fn” depending
on determined control statuses of the instrument and the
temperature measured by the evaporator probe (EP).
In the case that the evaporator probe is not used or in error , the
output Fn is activated only depending on the parameters “tn”, “tF”
and “FE”.
The parameters “tn” e “tF” decides the funs functioning when the
output configured as “ot” (compressor) is off.
When output “ot” is off , it is possible to set the instrument so that
that the output “Fn” continues to work in cycles according to the
times programmed in the parameter “tn” (fan activation time) and
“tF” (fan deactivation time).
When output “ot” is switched off the instrument activates the output
“Fn for the time “tn”, then deactivates it for the time “tF” and so on
whilst the otuput “ot” remains off.
Programming “tn” = oF the output “Fn” in “ot” off condition will
remain switched off.
Programming instead “tn” to any value and “tF” = oF the output “Fn”
in “ot” off condition will remain switched on.
The parameter “FE” instead decides whether the fans must always
be switched on independently of the defrosting status (“FE”=on) or
switched off during defrosting (“FE”=oF).
In this later case, it is possible to delay the start up of the fans even
after the end of the defrosting of the time set in the parameter
“Fd”.
When this delay is active the led FAN flashing to signal the delay in
progress.
When the evaporator probe is used the fans, as well as being
conditioned by the parameters “tn”, “tF and “FE”, are also
conditioned by a temperature control.

It is possible to set the disablement of the fans when the
temperature measured by the evaporator probe is higher than the
one set in the parameter “FL” (temperature too hot) or when it is
lower than the one set in the parameter “LF” (temperature too
cold).
Notes: It is necessary to pay attention to the correct use of this fans
temperature control functions because in the typical application of
refrigeration the stop of the fans evaporator stops thermal
exchange.
The relative differential that can be set in parameter dF” is also
associated with these parameters.
Remember that the fans functioning can be conditioned by the
“Door open” function by the digital input.
4.10 - ALARM FUNCTIONS
The alarm conditions of the instrument are:
- Probe errors : “E1”, “-E1”, “E2, “-E2”, “E3”, “-E3”
- temperature alarms: “H1”, “L1”, “H2”, “L2”
- External alarm: “AL”, “Pr”, “HP”, LP”
- Open door alarm: “oP”
The alarm functions of the instrument work on internal buzzer (if
present and programmed by par. “o.bu”) and on output desired, if
configured by the parameters “o1”, “o2”, “o3” ,“o4”,, depending on
what is set on the said parameters.
The buzzer (if “o.bu” = 1 or 3 or 4) is activated in alarm and can be
disabled (alarm silencing) manually by pressing any key of the
instrument.
The possible selections of output parameters for the alarm
signalling function are:
= At - when one wants the output to be activated in alarm and can
be disabled (alarm silencing) manually by pressing any key of the
instrument (typical application for sound signal).
= AL - when one wants the output to be activated in alarm status
but cannot be disabled manually and are therefore only disabled
when the alarm status ceases (typical application for a light signal).
= An - when one wants the output to be activated in alarm status
and that they remain activated even when the alarm has ceased
(Alarm memory). Disablement (recognition of memorised alarm)
can only be carried out manually by pressing any key when the
alarm has ended (typical application for light signal).
= -t - when one wants the function described as At but with an
inverse function (output activated in normal condition and disabled
in alarm status).
= -L - when one wants the function described as AL but with
inverse logic (output activated in normal conditions and disabled in
alarm status).
= -n - when one wants the function described as An but with
inverse working logic (output activated in normal conditions and
disabled in alarm status).
4.10.1 - TEMPERATURE ALARMS
The instrument has two fully configurable temperature alarms, each
with a maximum and minimum threshold.
The temperature alarm functions act in response to the readings of
the probes set in parameters “1y” e“2y”, alarm thresholds set in
parameters “1H”, “2H” (maxima alarms), “1L”, “2L” (minima
alarms) and the differentials for these, “1d, “2d”
Via the parameters “1y” and “2y” it is also possible to define
whether the alarm thresholds “1H”, “2H“, “1L”, “2L” are absolute or
relative to the set point.
Depending on the desired operation, parameters “1y” and “2y” can
be given the following values:
= 1: Absolute values based on Pr1 with display of label (H – L)
= 2: Relative values based on Pr1 with display of label (H – L)

Certain parameters also allow the user to delay the enabling and
intervention of these alarms.
These parameters are:
ASCON TECNOLOGIC - B05-- OPERATING INSTRUCTIONS - PAG. 10

“1P” and “2P”- these are the time periods during which
temperature alarms are disabled beginning with instrument start-up
if the instrument is in an alarm condition on start-up.
If there are no alarm conditions on start-up, the time period “xP” is
ignored.
“dA” - this is the time period during which temperature alarms 1
are disabled following the end of a defrost.
Note: During defrosts, and for time period “dA” after defrosts, alarm
1 is disabled, whereas during defrosts alarm 2 is always enabled.
“1t”, “2t” - these are the actuation delay times for temperature
alarms 1 and 2.
Temperature alarms 1 and 2 are enabled at the end of the
alarm-disabled time periods and activated after time periods “1t”
and “2t” when the temperature measured by the probe configured
for the alarm rises above or drops below the respective maximum
and minimum alarm thresholds.
Via the parameters “1A” and “2A” it is also possible to define at
will the action of the alarms on the regulating output and on the
alarm outputs (including buzzer).
This means for example that it is possible to change the regulating
output directly, deactivating it if there are temperature alarms on
the probes configured as “Au” (e.g. “antifreeze” function) or as “cd”
(e.g. condenser “dirty” function).
If both alarms are configured with reference to the same probe, the
instrument also allows the user to control pre-alarm notifications
(e.g. notifications that do not activate the alarm output and/or the
buzzer) and alarm notifications (which do activate the alarm output
and/or the buzzer).
The alarm thresholds will be the same as those set in parameters
“xH” and “xL” if the alarms absolute (“xy” = 1, 3, 5, 7, 9, 10),

The maxima and minima temperature alarms can be disabled by
setting the relevant parameters "A.Hx" and "A.Lx" = oF.
4.10.2 - EXTERNAL ALARMS (DIGITAL INPUTS)
The instrument can notify alarms external to the instrument by
activating one or more digital inputs configured with functions
programmed as “xF” = 4, 5, 12, 13, 14.
Simultaneously with the configured alarm notification (buzzer
and/or output), the instrument notifies the alarm displaying on the
display the label defined for the alarm (AL, Pr , HP, LP) alternating
with the variable defined in parameter “i.dS”.
The “i.xF”= 4 mode produces no action on the control outputs
whereas the other modes deactivate the “ot” output or deactivate
all control outputs when the digital input intervenes.

4.10.3 - OPEN DOOR ALARM
The instrument can signal an open door alarm by activating the
digital input with the function programmed as “xF” = 1, 2 or 3.
When the digital input is activated the instrument show oP and
after the delay programmed in parameter “oA”, the instrument
signals the alarm via the activation of the configured alarm output
(buzzer/ouput).
At the intervention of the open door alarm the inhibited output will
reactivated (fans or fans + compressor).
4.10.4 - MAIN VOLTAGE ALARMS
All the parameters concerning the voltage alarm functions are
contained in group “-UA”.
With the voltage alarms function it is possible to disable the control
outputs when the main voltage is lower or higher than the values
sets to the parameters:
"LU" - Low voltage Alarm (expressed in V x 10)
"HU" - High voltage Alarm (expressed in V x 10)
At the intervention of the alarm (and after the “Ud” time) all the
control outputs are disabled, the alarm is activated and the
instrument visualises HU (High voltage) or LU (Low voltage and
the variable set in parameter “dS” alternately on the display.
If the main voltage alarms are activated in this mode will be
displayed the variable P5 that represents the main voltage with a
value decreased of 150 V.
The main voltage tension measured by the instrument will be
therefore V = P5 + 150.
If the voltage measure is not correct it is possible to modify it
through the par. "OU".
4.11 - FUNCTIONING OF KEYS “U” AND “DOWN/AUX”
All the parameters concerning keyboard functions are contained in
the group “-tS”.
Two of the instrument keys, in addition to their normal functions,
can be configured to operate other commands.
The U key function can be defined by the parameter “UF” while the
DOWN/AUX key function can be defined by the parameter “Fb”
Both the parameters have the same possibilities and can be
configured for the following functions:
=oF - The key carries out no function.
= 1 - Pressing the key for at least 1 second, it is possible to
enable/disable the auxiliary output if configured (“Fo”=2).
= 2 - Pressing the key for at least 1 second, it is possible to select
the mode Economic/Normal in rotation. Once selection has been
made, the display will flash the active set point code for about 1
sec. (SP, Ec).
= 3 - Pressing the key for at least 1 second, it is possible to switch
the instrument from the ON status to Stand-by status and vice
versa.
= 4 - Pressing the key for at least 1 sec activates/deactivates a
“Turbo” cycle.
4.12 - ACCESSORIES
The instrument is equipped with a connector that allows the
connection of some accessories described as follow.
4.12.1 - PARAMETERS CONFIGURATION BY “A01”
It is possible the transfer from and toward the instrument of the
functioning parameters through the device A01 with 5 poles
connector.
This device A01 it’s mainly useable for the serial programming of
the instruments which need to have the same parameters
configuration or to keep a copy of the programming of an
instrument and allow its rapid retransmission.
The same device can connect the instrument via USB to a PC and
through the proper configuration software tools "TECNOLOGIC
UniversalConf”, it’s possible to configure the operating parameters.
To use the device A01 it’s necessary that the device or instrument
are being supplied.

4.12.3 - RS 485 SERIAL INTERFACE BY “TLCNV”
The instrument can be connected by a special cable to the TLCNV
device (mod. C - TTL/RS485 interface), by means of which it is
possible to connect the regulator with a net to which other
instruments (regulators of PLC) are connected, all depending
typically on a personal computer used as plant supervisor.
Using a personal computer it is possible to acquire all the function
information and to program all the instrument’s configuration
parameters. The software protocol adopted for the instrument is a
MODBUS RTU type, widely used in several PLC and supervision
programs available on the market (B04/B05 series protocol manual
is available on request).
If the instrument is used with TLCNV program by the parameter
