Caution:
l The sensor head is fragile and can easily be damaged. Using cable ties to secure the sensor head or sensor cable is not recommended and
invalidates the warranty.
To help place the appliance sensor, the parameter calibration 1 (CA1) defines an offset temperature.

3.2 how to mount the evaporator sensor
The evaporator sensor measures the temperature of the evaporator.
ems controllers use the temperature of the evaporator to activate and terminate defrost cycles.
The evaporator sensor should be placed in the immediate proximity of the evaporator. Mount the sensor head inside the
evaporator cooling fins, as shown below.
The sensor head must be mounted securely to prevent being dislodged due to vibration.
For coolers fitted with a defrost heater, the evaporator sensor should be placed as far away as possible from the heating ele-
ment, i.e. at the opposite end of the evaporator.
If the evaporator sensor measures the localized heating from the heating element, defrost cycles will terminate before the
whole evaporator has had the opportunity to defrost.
