1.- Presentation
PROPlus is the global electronic solution to manage positive and negative cold room stores, in combination with:
ŸStandard condensing units
ŸStreamlined condensing units
ŸOr as a service panel in decentralised systems.
It has a general circuit breaker of up to 16A, high IP65 degree of protection for installation in damp environments, is
easy to install thanks to its new connection strip and intuitive menus with help texts that make programming easier
using its backlit LCD display.
1.1.- Maintenance
Clean the surface of the unit with a soft cloth, water and detergent. Do not use abrasive detergents, petrol, white
spirits or solvents.
Units that include rechargeable electrical accumulators:
This unit includes accumulators that should be replaced when the unit's battery life is under the duration
assigned in its specifications. At the end of the useful life of the unit, the accumulators should be taken to a
selective waste collection centre or returned to the manufacturer.
1.2.- Cautions
-Using the unit not observing the manufacturer's instructions may alter the appliance safety requirements. Only
probes supplied by AKO should be used for the unit to operate correctly.
2
-From -40 ºC to +20 ºC, if the NTC probe is extended to 1000 m with at least 0.5 mm cable, the maximum
deviation will be 0.25 ºC (cable for probe extension ref. AKO-15586).
-Only NTC probes supplied by AKO should be used for the appliance to operate correctly.
-The AKO-15640 should be installed in a place protected from vibrations, water and corrosive gases, where the
ambient temperature does not exceed the value indicated in the technical data.
-For the reading to be correct, the probe should be used in a place without heat influences apart from the
temperature you want to measure or control.
-Always disconnect the power supply to do the wiring. The power supply circuit should have a main switch and
residual current protection outside the panel (according to 2 2 R.E.B.T.). The power supply cable will be H05VV-F
2 2
2x2.5 mm or H05V-K 2x2.5 mm .
IMPORTANT:
ŸThe function of each probe depends on the "probe setting" parameter (See probe configuration on page 11).
ŸThe AUXILIARY relay is programmable, and its operations depends on the configuration (See page 23).
ŸThe function of the digital inputs depends on the configuration (See page 22).
ŸThe recommended currents and powers are the maximum working currents and powers.
2.- Battery
You should connect the battery cable (1) and plate connector
(2) before installing the unit.

3.- Recommendations
ATTENTION!!
Disconnect the voltage before carrying out any operations inside the electrical panel.
All wiring should be according to current standards and should be carried out by authorised staff.
Only carry out the wiring foreseen in the wiring diagrams.
ŸWorking ambient temperature: 0 ºC to 50 ºC
ŸRated isolation voltage Ui = 440 V~
ŸElectrical panels with IP65 degree of protection
ŸCEM 1 Environment
ŸTerminals for copper conductors
ŸResistance to short-circuits Icc=4.5 kA
Panel installation:
Do not knock or move the panel abruptly.
Carry out the wiring according to the installation manual.
The probes and their cables should NEVER be installed in a conduit together with power, control or feeder cables.
The earth terminals that the panels contain are installed to guarantee the continuity of earthing, however, earthing
is not carried out by the terminal and should be carried out outside the panel.
The neutral ratings are TT or TNS. The IT rating should not be used.
Circuit breakers (protective switches) are of the phase/s + neutral, curve C type, guaranteeing switching and
protection against overcurrent.
Close the panel when your are not working on it.
Main switch connection and residual current protection outside the electrical panel according to low voltage
electrotechnical regulations.
Checks before starting the panel up:
The power supply voltages and frequencies will be those indicated in the table and diagram corresponding to each
panel model.
Check that there are no loose parts or foreign bodies on connections or switchgear.
Check that there is no dust or damp inside the panel.
Check the correct fastening of the switchgear and components.
Check the correct tightening of the screws and power connections.
Check the correct connection of the power conductors.
Check the correct insulation of the outer lines and that they do not mechanically force the inner connections of the
panel.
Checks during the panel start-up:
Check that no electric arcs occur.
Check that the relays or contactors do not produce ratios.
Check that there is no overheating in cables, controllers and the rest of the switchgear.
Checks after the first 24 hours of operation:
Check that no overheating occurs.
Retighten screws and power connections.
Periodical preventive maintenance:
The panel should remain closed using its anchors.
Retighten the power connections once a year.
Check the wear of the switchgear once a year.

COMPRESSOR PROTECTION DELAY
This protects the compressor, preventing continuous stops and start-ups in certain exceptional cases.
The Comrpessor Protection parameter allows choosing between 2 types of delay:
OFF-ON: Minimum time the compressor should stay stopped before each start-up.
ON: Minimum time the compressor should stay operating before each start-up.
The Protection delay time parameter defines the time of the previous parameter.
OPERATION IN THE EVENT OF A FAULT IN PROBE 1
If probe 1 fails (failure, disconnection, etc. ), the compressor operates according to times programmed in the following
parameters:
Compressor ON fault s1: Time of the compressor operating in the event of a fault in probe 1.
Compressor OFF fault s1: Time of the compressor stopped in the event of a fault in probe 1.
SET POINT LOCKINGS
Using the Set Point upper limit and Set Point lower limit parameters, it is possible to set a top and bottom limit for
the Set point (SP) parameter, which prevents being able to set a set point that is too low or too high that might
damage the installation or the stored product.
STOP COMPRESSOR WHEN THE DOOR IS OPENED
This defines if the compressor will be stopped whenever the cold room's door is opened. To do so, one of the digital
inputs should be configured as "door contact" (See page 22).
If the door stays open longer than the value programmed in the Inact. with door open parameter, the compressor will
return to normal operation (See page 22).

8.2.- Defrost control
Type of defrost
This is chosen using the Defrost type parameter that defines the behaviour of the controller during the defrost
process.

16
Defrost start
Defrost will start if:
ŸThe time programmed in the Defrost frequency parameter has passed since the start of the last defrost.
The parameter Defrost mode defines how this time is counted:
žFrequency: Total time passed between defrost starts.
žCompressor sum: Total time of the compressor operating between defrost starts.
žReal Time Clock: Defrost starts when one of the times programmed in the Defrost 1 to 8 on
the u menu is reached. (The defrost frequency is not taken into account).
ŸWe press the N key for 5 seconds.
End of defrost
The defrost stops if:
ŸThe temperature programmed in the Defrost final temperature has been reached in probe 2 (this requires
having a defrost probe connected to S2).
ŸThe time configured in the Defrost duration has passed (maximum defrost duration). The I icon is shown on
the display if the Signals end defrost time parameter is configured in “Yes”.
ŸWe press the N key for 5 seconds.
REMARK: If the Defrost duration is configured to 0, no defrosts are carried out.
Drip time after defrost
This is establishing using the Drip time parameter of the H menu and defines the time added at the end of the defrost
to allow removing any water left in the evaporator.
During this time, the compressor and fans will be stopped (except if the defrost is by air).
Message displayed during defrost
This is established using the Defrost message parameter, and you can choose between displaying the real
temperature captured by probe 1, show the temperature capture by probe 1 at the start of the defrost, or display the
DEFROST message.
The Message duration parameter defines how long this message is displayed, after the drip time and start up delay of
the fans (See page 15).
Other parameters
Using the Defrost at Start-up parameter, you can configure if the unit carries out or not a defrost when it receives
power (first start up or after a fault in the power supply).
If the "YES" option is chosen, defrost starts after the time defined in the Defrost delay at Start-up parameter on the
H menu.
2nd defrost
It operates in the same way as the defrost, but acts on the auxiliary relay, controlled by probe 2 or 3 and is used to
control the defrost in a second evaporator. (The AUX relay must be configured as 2nd defrost).
The configuration parameters of the 2nd defrost are configured from the v menu.
Remote defrost
This function allows activating the defrost of the unit using an external button, connecting it to one of the digital inputs
that must be configured as "remote defrost”.

17
8.3.- Fan control
Fan control is carried out using probe 2 and taking the following parameters into account:
ŸFan stop temperature: It defines the temperature at which the fans stop.
ŸFans differential s2: It defines the temperature differential of probe 2 (evaporator).
ŸStop when compressor OFF?: It defines if the fans stop in each compressor stop.
ŸFans state during defrost: It defines the status of the fans during the defrost.
ŸFans delay after defrost: If configures the time that passes before starting the fans up, at the end of a defrost.
ŸStop when opening door: It defines if the fans are stopped when the cold room's door is opened (this requires
having configured one of the digital inputs as door contact).
If the door stays open longer than the value programmed in the Inact. with door open parameter, the fans
return to normal operation.
If probe 2 is not connected or an error in the probe is detected, the fans will always be operating without taking into
account the temperature related parameters, but taking the rest of the parameters into account.
8.4.- Light control
The unit has an additional relay to control the cold room's lights.
Just press the ? key to turn the lights on/off.
This function is even active when the unit is in Stand-by.
Light timing
The unit activates the lights whenever the cold room's door is detected to have been opened, and turns them off after
the time programmed in the Cold room light timing parameter, even though the door stays open. If time is
configured at “0”, timing does not start.
One of the digital inputs should be configured as "Door contact”.

8.5.- Pump down function
This function foresees problems in the compressor caused by movements of coolant, using a stop/start technique of the
installation, controlled via the liquid solenoid, the low pressure controller and the compressor itself.
The auxiliary relay must be configured as "Pump down control", the liquid solenoid must be connected to the 40 and 41
terminals and there must be a low pressure controller connected as indicated in the diagrams (See page 7).
STOP
When the temperature in probe 1 reaches the set point (SP) value, the liquid solenoid closes.
Due to the compressor continuing to operate (COMP. relay ON), the pressure drops quickly in the evaporator, and
therefore activates the low pressure controller and the compressor stops.
If during this process the low pressure controller does not detect the change of pressure, the controller will stop after the
safety time defined in Pump down duration.
START
When the temperature in probe 1 reaches the set point value plus the differential, the liquid solenoid opens, making the
pressure in the evaporator increase and deactivating the low pressure controller, which will start the compressor up.
When a balance is reached between the high and low pressure before the start up, this is much gentler and lengthens
the life of the compressor.
If after a time after opening the liquid solenoid the low pressure controller does not deactivate, the controller closes the
solenoid again and activates the low pressure alarm. This time is defined using the Pump down On delay parameter.
STAND-BY WITH PUMP DOWN
If the pump down function is active and the compressor is operating, when the Stand-by function starts the unit stops
the compressor in a controlled manner as explained in the "STOP" section and displays on the screen the "Pump
down" message, and when it has finished, it automatically goes to the Stand-by mode.

8.6.- Alarms
The unit warns the user with a message on the screen of the activation of a relay or the
activation of an acoustic signal in certain circumstances, according to the programming of
the following parameters:
Alarm configuration
It defines how the values of the different temperature alarms are defined:
Relative to the SP: They are defined indicating the temperature variation regarding the set point for the alarm to
activate. This option enables us to change the set point without having to reset the maximum
and minimum alarms.
Absolute: They are defined indicating the absolute temperature value for the alarm to activate.
Maximum / minimum temperature alarm
It displays the message “HIGH TEMP ALARM” or “LOW TEMP. ALARM” when the temperature in probe 1 reaches the
value configured in the Maximum alarm sensor 1 and Minimum alarm sensor 1 parameters respectively.
The sound alarm and alarm relay is activated.
Alarm differential
It establishes the differential for the maximum and minimum alarm parameters (hysteresis).
Example
We configure the following parameters in a controller:
Set point=2, Maximum alarm probe 1=10, Alarm differential=2
ŸIf it is configured as “Relative to the SP”, the maximum temperature alarm activates when 12 degrees
are reached in probe 1, and deactivates when 10 degrees are reached.
ŸIf it is configured as “Absolute”, the maximum temperature alarm activates when 10 degrees are
reached in probe 1, and deactivates when 8 degrees are reached.
Delays
They define the delay time in minutes from a certain event, until the activation of the temperature alarms.
ŸTemperature alarm delay: Delay from when the temperature is reached.
ŸStart-up delay: Delay from which the unit receives power supply (start up or after a fault in the power supply). This
allows starting up the installation avoiding constant alarm statuses.
ŸAlarm delay after defrost: Delay at the end of a defrost.
ŸOn-Off door alarm delay: Delay from the deactivation of the digital input configured as door contact.
ŸOff-On door alarm delay: Delay from the activation of the digital input configured as door contact.
Alarm relay after key
This defines the status of the alarm relay after silencing it (pressing the ESC key).
External alarm / severe external alarm
It displays the EXTERNAL ALARM or SEVERE EXT. ALARM, on activating the digital input configured as external
alarm or severe external alarm. The severe external alarm also stops the unit's control functions (compressor, fans,
defrost and auxiliary relay).
One of the digital inputs must be configured as external alarm or as severe external alarm.
The sound alarm and alarm relay is activated.

value configured in the Maximum alarm sensor 1 and Minimum alarm sensor 1 parameters respectively.
The sound alarm and alarm relay is activated.
Alarm differential
It establishes the differential for the maximum and minimum alarm parameters (hysteresis).
Example
We configure the following parameters in a controller:
Set point=2, Maximum alarm probe 1=10, Alarm differential=2
ŸIf it is configured as “Relative to the SP”, the maximum temperature alarm activates when 12 degrees
are reached in probe 1, and deactivates when 10 degrees are reached.
ŸIf it is configured as “Absolute”, the maximum temperature alarm activates when 10 degrees are
reached in probe 1, and deactivates when 8 degrees are reached.
Delays
They define the delay time in minutes from a certain event, until the activation of the temperature alarms.
ŸTemperature alarm delay: Delay from when the temperature is reached.
ŸStart-up delay: Delay from which the unit receives power supply (start up or after a fault in the power supply). This
allows starting up the installation avoiding constant alarm statuses.
ŸAlarm delay after defrost: Delay at the end of a defrost.
ŸOn-Off door alarm delay: Delay from the deactivation of the digital input configured as door contact.
ŸOff-On door alarm delay: Delay from the activation of the digital input configured as door contact.
Alarm relay after key
This defines the status of the alarm relay after silencing it (pressing the ESC key).
External alarm / severe external alarm
It displays the EXTERNAL ALARM or SEVERE EXT. ALARM, on activating the digital input configured as external
alarm or severe external alarm. The severe external alarm also stops the unit's control functions (compressor, fans,
defrost and auxiliary relay).
One of the digital inputs must be configured as external alarm or as severe external alarm.
The sound alarm and alarm relay is activated.

Defrost finished by time alarm
The icon I is displayed when a defrost ends for maximum time. (The Signal end defrost time must be configured as
“Yes”).
The sound alarm and alarm relay is not activated.
Low pressure alarm
It displays the LOW PRESSURE ALARM message when low pressure is detected in the circuit, or if pressure does not
increase during the starting operation from pump down (See page 18). In both cases, there should be a low pressure
controller connected to the unit (See page 7).
The compressor stops and activates the sound alarm and alarm relay is not activated.
8.7.- Data logging
It allows displaying the temperatures logged during the selected time period.
The probe designed for temperature logging depends on the probe configuration (See page 11).
Press the P and O keys at the same time for 5 seconds to access data logging.
Data is saved in log blocks and the unit can store up to 366 blocks and each block contains 96 logs.
Each log contains the temperature measured by the unit, and the data and time of this measurement.
The "registry interval” parameter defines the time that passes between the capture of a datum and the next one.
When the last available block (N365) has been completed, the unit starts again with the first block (N000), therefore,
the time interval the unit is capable of storing depends on the configured log interval.
Use the N or Q keys to select a block and press SET to display the logged data.
