1 MEASUREMENTS AND INSTALLATION
Measurements are expressed in mm (inches). Front installation on a plastic or metal panel (with
elastic holding flaps).
N.B.
The metal panel must be between 0.8 and 1.5 mm (1/32 and 1/16 in) thick, while the
plastic panel must be between 0.8 and 3.4 mm (1/32 and 1/8 in)
INSTALLATION PRECAUTIONS
- ensure that the working conditions are within the limits stated in the TECHNICAL SPEC-
IFICATIONS 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.
3 FIRST-TIME USE
1. Carry out the installation following the instructions given in the section MEASUREMENTS
AND INSTALLATION.
2. Power up the device: 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:
PAR. DEF. PARAMETER
SP 0.0 setpoint
P0 1 type of probe
P2 0 temperature measurement unit
d1 0 type of defrost
Next check that the remaining settings are appropriate; see the section CONFIGURATION
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. To perform the configuration upload or download, connect the EVJKEY programming key.
To activate real-time functions, connect the EVlinking RS-485 EVIF23TSX converter.
To control the device using the EVconnect app, connect the EVlinking BLE EVIF25TBX
module then synchronise it with the app.
To control the device using the EPoCA monitoring system or a third-party MODBUS TCP
system:
- connect the EVlinking Wi-Fi EVIF25TWX module to the device and then to a local
Wi-Fi network
- connect the EVlinking RS-485 EVIF24TSX converter to the device then to an IoT
EV3 Web gateway or EVD Web. Next connect this to a free Ethernet port of a
router or an Ethernet hub connected to a local network.
7. Power up the device again.
4 USER INTERFACE AND MAIN FUNCTIONS
4.1 Keypad
Controllers for refrigerated cabinets and display units
2 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
- the 0-10 V analogue outputs operate properly provided that the device is powered by at least 11 VDC
- if the device has a power supply of 12 Vdc, the outputs 12... 24 Vdc will each deliver 12 Vdc max. 2.5 A; if the device has a power supply of 24 Vdc, the outputs 12...
24 Vdc will each deliver 24 Vdc max. 2.5 A
- port for remote indicator is only available in model EVY238DN3PFT
Manag. of remote indicator

no
yes
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 further information, contact the EVCO sales network

4.5 Setting the setpoint (if r3 = 0, default)
Check that the keypad is not locked.
1. Touch the SET key
Touch the UP or DOWN key within 15 s to set the value within the
2
limits r1 and r2 (default "-40... 50")
3. Touch the SET key (or take no action for 15 s)
4.6 Setting the 0-10 V evaporator fan speed for normal operation (percentage 0-10
V output; available if Ao1... Ao3 = 3 and F30 = 0)
Check that the keypad is not locked.
