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 below shows the recommended position of the appliance sensor. The appliance sensor measures the air tem-
perature after the air has been drawn over the products. The return air provides a close approximation of the product tem-
perature.
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 using a P-clip.
The sensor head should not be completely covered by the P-clip or the sensor will not function correctly.
