MEASUREMENTS AND INSTALLATION | Measurements in mm (inches)
1.1
User interface
To be fitted to a plastic or metal panel (with elastic holding flaps).
N.B.
The thickness of a metal panel must be between 0.8 and 1.5 mm (1/32 and 1/16 in),
while that for a plastic panel must be between 0.8 and 3.4 mm (1/32 and 1/8 in).
1.2
Control module
To be installed on an electrical panel, on spacers (not provided).
N.B.
Any metal parts must be far enough away so as not to compromise safety distances.
INSTALLATION PRECAUTIONS
-
ensure that the working conditions are within the limits stated in the TECHNICAL
SPECIFICATIONS section
-
do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations
or shocks
-
in compliance with safety regulations, the device must be installed properly to ensure
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.

ELECTRICAL CONNECTION
N.B.
- use cables of an adequate section for the current running through them
- to reduce any electromagnetic interference, locate the power cables as far away as
possible from the signal cables.
PRECAUTIONS FOR ELECTRICAL CONNECTION
-
if using an electrical or pneumatic screwdriver, adjust the tightening torque
-
if the device is moved from a cold to a warm place, humidity may cause condensation
to form inside. Wait for about an hour before switching on the power
-
make sure that the supply voltage, electrical frequency and power are within the set
limits. See the section TECHNICAL SPECIFICATIONS
-
disconnect the power supply before carrying out any type of maintenance
-
do not use the device as a safety device
-
for repairs and for further information, contact the EVCO sales network.

FIRST-TIME USE
1.
Carry out the installation following the instructions given in the section MEASUREMENTS
AND INSTALLATION.
2.
Power up the device as set out in the section ELECTRICAL CONNECTION: an internal
test will start up.
The test normally takes a few seconds; when it is finished the display will switch off.
3.
Configure the device as shown in the section Setting configuration parameters.
Recommended configuration parameters for first-time use:

0 = electric
1 = hot gas
2 = compressor stopped
Then check that the remaining settings are appropriate; see the section CONFIGURA-
TION PARAMETERS.
4.
Disconnect the device from the mains.
5.
Make the electrical connection as shown in the section ELECTRICAL CONNECTION,
without powering up the device.
6.
To use the device with the Evconnect app, connect the EVIF25TBX module. To use the
device with the EPoCA remote monitoring system, connect the EVIF25TWX module.
When connecting to an RS-485 network, connect the EVIF22TSX interface. To activate
real-time functions, connect the EVIF23TSX module.
If using EVIF22TSX or EVIF23TSX, set the bLE parameter to 0.
7.
Power up the device.

If Loc = 1 (default) and 30s have elapsed without the keys being pressed, the display will show
the “Loc” label and the keypad will lock automatically.
4.2
Unlocking the keypad
Touch a key for 1 s: the display will show the label “UnL”.
4.3
Setting the setpoint (if r3 = 0, default)
Check that the keypad is not locked.
1.
Touch the SET key.
2.
Touch the UP or DOWN keys within 15 s to set the value within
the limits r1 and r2 (default "-40... 50”)
3.
Touch the SET key (or take no action for 15 s).
4.4
Activating manual defrost (if r5 = 0, default)
Check that the keypad is not locked and that overcooling is not active.
1.
Touch the DEFROST key for 4 s.
If P3 = 1 (default), defrost is activated provided that the evaporator temperature is lower than
the d2 threshold.
4.5
Switching the cabinet light on/off (if u1c... u5c = 5)
1.
Touch the CABINET LIGHT key.
4.6
Switching the cabinet light on/off (if u1c... u5c = 10 or 11)
1.
Touch the CABINET LIGHT key (for 2 s if u1c... u5c = 5).
