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 for the controllers to have IP65 protection, the gasket should be properly installed
between the apparatus and the perimeter of the panel cut-out where it is to be fitted.
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.
3.1 Fastening units for panel mounting:
max. 18 mm
PANEL CUT-OUT
70,5
3.2 Connection:
The probe and its lead should NEVER be installed in ducting along with power, control or
power supply wiring.
The power supply circuit should be connected with a minimum 2 A, 230 V, switch located
close to the unit. Power supply cables should be H05VV-F 2x0,5 mm
Section of connecting wires for relays contacts should be 2,5 mm

LED COOL
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 not due to a
programmed parameter.
LED Def
Permanent: Indicates defrost in opera-
tion.
LED Alarm
Permanent: Alarm indicator enabled.
Flashing: Alarm detected, but display
maintained.
DT LED
Indicates last defrost ended by time.
LED ºC
Permanent: Degrees ºC indicator.
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.
- Pressing
+
keys simultaneously to ACCEPT THE NEW SET POINT. The display returns
to the CURRENT TEMPERATURE display status and LED ºC or ºF stops flashing.
When PA is displayed, PASSWORD programmed in L5 parameter of tid menu should be
entered to access the CURRENT SET POINT.
- Press
+
keys simultaneously. 0 will be displayed to ENTER PASSWORD.
- Press
or
keys to CHANGE NUMBER and DISPLAY PASSWORD programmed.
- Press
+
keys simultaneously to ACCEPT PASSWORD. The CURRENT SET POINT value
will be displayed and it can be already modified.
