3.1 How to mount the appliance sensor
The appliance sensor measures air temperature of
the refrigerated compartment by measuring the
return air temperature.
The diagram to the right shows the recommended
position of the appliance sensor. The appliance
sensor measures the air temperature after the air
has been drawn over the products.
The returnair provides a close approximation of the
product temperature.
To measure the return air temperature, secure the
sensor to allow air to flow over the sensor head.
The sensor head should be placed at a right-angle
to the air flow and secured usinga P-clip.
The sensor head should not be completely covered
by the P-clip or the sensor will not function
correctly.
Note
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.
Note
To help place the appliance sensor, the parameter calibration1 (CA1) defines an offset
temperature. See “Calibration” 1 (CAT1)”.
