1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, snap-in brackets provided.
INSTALLATION PRECAUTIONS
- The thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in)
- 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
2 ELECTRICAL CONNECTION
N.B.
-Use cables of an adequate section for the current running through them
-To reduce any electromagnetic interference connect 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 has been moved from a cold to a warm place, the humidity may have
caused condensation to form inside. Wait 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 doing any type of maintenance
-Do not use the device as safety device
-For repairs and for further information, contact the EVCO sales network
3 FIRST-TIME
1. Install following the instructions given in the section MEASUREMENTS AND INSTALLA-
TION.
2. Power up the device as shown in the section ELECTRICAL CONNECTION and an internal
test will be run.
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.
PAR. DEF. PARAMETER MIN... MAX.

P0 1 probe type 0 = PTC 1 = NTC
P2 0 temperature unit of measurement 0 = °C 1 = °F
d1 0 defrost type 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 with-
out powering up the device.
6. For the connection in an RS-485 network, connect the EVIF22TSX or EVIF23TSX inter-
face. To activate real time functions, connect the EVIF23TSX module. To use the device
with the app EVconnect, connect the EVIF25TBX interface. To use the device with the
EPoCA remote monitoring system, connect the EVIF25TWX module. If the EVIF22TSX
or EVIF23TSX interface is used, set parameter bLE to 0.
7. Power up the device.
4 USER INTERFACE AND MAIN FUNCTIONS
4.1 Switching the device on/off
1. If POF = 1, touch the ON/STAND-BY key for 4 s.
If the device is switched on, the display will show the P5 value ("cabinet temperature" default);
if the display shows an alarm code, see the section ALARMS.
