1 IMPORTANT
1.1 Important
Read these instructions carefully before installation and commission-
ing and follow the recommendations regarding installation and for
electric connection. Keep these instructions with the instrument for
future consultation.
The instrument must be disposed of in compliance with
the local Standards regarding the collection of electrical
and electronic appliances.
2 DIMENSIONS AND INSTALLATION

2.2 Installation
Panel with click brackets supplied.
2.3 Installation recommendations
• the thickness of the panel must not exceed 8.0 mm (0.314 in)
• make sure that the work conditions (temperature of use, humidity,
etc.) lie within the limits indicated in the technical data
• do not install the instrument in vicinity of heat sources (resistances,
hot air pipes, etc.), appliances with strong magnets (large diffusers,
etc.), places subject to direct sunlight, rain, humidity, excessive dust,
mechanical vibrations or shocks
• in compliance with Safety Standards, the protection against any
contact with electric parts must be assured via correct installation of
the instrument; all parts that ensure protection must be fixed in a way
that they cannot be removed without using tools.
3 ELECTRIC CONNECTION
3.1 Preliminary considerations
With reference to the wiring diagram:
• port 1 is the serial port for communication with the supervision
system (through a serial interface, via TTL, with MODBUS communi-
cation protocol), with graphic diagram (through a serial interface)
or with the programming key; the port must be used just for one
purpose
• port 2 (on request) is the port for communication with the remote
indicator. The latter shows the temperature of the room.
3.2 Electric connection
3.3 Recommendations for the electric connection
• do not operate on terminal boards using electric or pneumatic screw-
ing devices
• if the instrument has been taken from a cold to a hot place, the
humidity could condense inside; wait about 1 hour before apply-
ing power
• make sure that the power supply voltage, the frequency and the
operational electric power of the instrument correspond with those
of the local power supply
• disconnect the power supply before proceeding with any type of
maintenance
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the
Evco sales network.
4 FUNCTIONING
4.1 Preliminary considerations
The following functioning cycles exist:
• automatic cycle
• heating manual cycle
• cooling manual cycle.
The automatic cycle is made up of the following phases:
- a retarding provering phase
- a storing phase
- an awakening phase
- a provering phase
- a slowing phase
On conclusion of one phase the instrument passes automatically to
the next one.
5 AUTOMATIC CYCLE
5.1 Start/stop of the automatic cycle
To start the cycle:
• make sure that the instrument is in stand-by and that there is no
procedure in progress
• press : the display will show the first label available
• press or within 15 s to select “Auto”
• press within 15 s: the display will show the following 3 times in
succession:
- the conclusion time of the provering phase (e.g. “02:00”)
-“dd” followed by the two numbers of the day of conclusion of the
provering phase (e.g. “dd26”)
-“MM” followed by the two numbers of the month of conclusion of
the provering phase (e.g. “MM03”)
• press within 9 s: the display will show “Go”
• press within 15 s: the LED will switch on and the retarding-
provering phase will be started.
If the automatic cycles are not enabled (parameter P7 = 0), the “Auto”
label will not be displayed.
The end time of the provering phase is displayed in the 24 hour format
(hours:minutes). The time proposed is the same as the last automatic
cycle started but relative to the next day.
In the example, the provering phase will be concluded at 02:00 on
26 March. The display will show all information for 1 s.
If parameter P9 is set at 0, the display will only show the conclusion
time of the provering phase.
To stop the cycle:

humidity). If the temperature of the room falls below that established
with parameter rU1, humidification will not be available.

8 USER INTERFACE
8.1 Preliminary considerations
The following functioning states exist:
• the “on” status (the instrument is powered and a functioning cycle
is in progress: the regulators can be switched on)
• the “stand-by” status (the instrument is powered but no functioning
cycle is in progress: the regulators are off)
• the “off” status (the instrument is not powered).
Successively, the term “switch-on” means the passage from the stand-
by status to the on status; the term “switch-off” means the passage from
the on status to the stand-by status.
If the power supply is shut-off during the stand-by status, the same
status will be proposed again when the power supply is restored.
If the power supply is shut-off during the on status, instrument function-
ing will depend on parameter P6 when the power supply is restored.
8.2 The display
If the instrument is on, during normal functioning the display will
show the size established via parameter P4:
• if P4 = 0, the display will show the temperature of the room if a
functioning cycle is in progress and will be off if the instrument is in
stand-by
• if P4 = 1, the display will show the end time of the provering phase
if a functioning cycle is in progress and will be off if the instrument
is in stand-by
• if P4 = 2, the display will show the temperature of the room (for 3 s)
alternating with the end time of the provering phase (for 1 s) if a
functioning cycle is in progress and will be off if the instrument is in
stand-by
• if P4 = 3, the display will show the temperature of the room if a
functioning cycle is in progress and the real time if the instrument is
in stand-by
• if P4 = 4, the display will show the end time of the provering phase
if a functioning cycle is in progress and the real time if the instrument
is in stand-by

(1) the unit of measurement depends on parameter P2
(2) appropriately set the parameters relative to the regulators after the modification of parameter P2
(3) if the parameter P4 is set at 1 or 2 and a heating or cooling manual cycle is in progress, the instrument will function as if the parameter P4 is set at 0
(4) if the parameter P4 is set at 4 or 5 and a heating or cooling manual cycle is in progress, the instrument will function as if the parameter P4 is set at 3
(5) for example: if on activation of the awakening phase, the room temperature is 4.0 °C, the SEt2 parameter is set at 16.0, the dur2 parameter is set at 02:00 h:min and the rn1 parameter is set at 2, for the first 60 min
of the awakening phase the work set-point will be 10.0 °C and for the remaining 60 min it will be 16.0 °C
(6) for example: if on activation of the provering phase, the room temperature is 16.0 °C, the SEt3 parameter is set at 26.0, the dur2 parameter is set at 02:00 h:min and the rn2 parameter is set at 2, for the first 60 min
of the awakening phase the work set-point will be 21.0 °C and for the remaining 60 min it will be 26.0 °C
(7) humidification is not available during the cooling manual cycle
(8) the parameter has effect also after the interruption of the power supply, which takes place when a functioning cycle is in progress
(9) the time established via the parameter is counted also when the instrument is in the stand-by status
(10) defrosting is only activated during the retarding-provering phase, during the storing phase and during the cooling manual cycle. If at the end of a storing phase defrosting is in progress, this will be interrupted
on start-up of the awakening phase (during the phases and functioning cycles in which the defrosting is not activated, the count of the defrosting interval remains frozen)
(11) the instrument memorises the count of the defrosting every 30 mins. The modification of parameter d0 has effect from the end of the previous defrosting interval or from the activation of defrosting in manual mode.
