3.1 Fastening
3.2 Connection:
The probe and its lead should
NEVER
be installed in duc-
ting along with power, control or power supply wiring.
The power supply circuit should be connected with a mini-
mum 2 A, 230 V, switch located close to the unit. Power
supply cables should be H05VV-F 2x0,5 mm
2
or H05V-K
2x0,5 mm
2
.
Section of connecting wires for relays contacts should be
2,5 mm
2
.
3- Installation
The controller should be installed in a place protected from vibrations, water and corrosive
gases, and where ambient temperature does not surpass the value specified in the technical
data.
In order to give a correct reading, the probe should be installed in a place without heat
influences other than the temperature that is to be measured or controlled.

LED Cool (Compressor)
Permanent:
Cooling relay COOL (com-
pressor) energised.
Flashing:
Because of the temperature
detected by Sensor 1 (TEM), the COOL
relay should be energised, but is no due to
a programmed parameter.
LED Fan
Permanent:
Fan relay energised.
Flashing:
Because of the temperature
detected by Sensor 2 (DEF), the Fan relay
should be energised, but is no due to a pro-
grammed parameter.

5- Adjustment and configuration
It should only be programmed or modified by personnel who are fully conversant with the
equipment operation and possibilities.
5.1 Set Point temperature
The factory SET POINT default value is 0.0 ºC.
- Press
key for at least 5 seconds to DISPLAY SET POINT. It displays the CURRENT SET
POINT value and LED ºC or ºF starts flashing.
- Press
or
keys to CHANGE SET POINT into the required value.
- Press
key to ACCEPT THE NEW SET POINT. The display returns to the CURRENT TEM-
PERATURE display status and LED ºC or ºF stops flashing.
- Press the
key to exit the temperature set point without modifying the value.
