Condenser sensor
Ambient light sensor
Door sensor
The condenser sensor is used to protect the compressor
against high pressure when the condenser is blocked or
the condenser fan fails.
The ambient light sensor is used to detect opening
hours of the shop.
The door sensor is used to detect buying activity and to
stop the fan when the door is opened.
Condenser sensor
Place the sensor at the liquid side of the condenser.
Use a metal bracket or metal tape to ensure good
thermal conductivity. Be sure that the cable does not
pass hot spots at the compressor or condenser that
exceeds 80°C.
Placement of sensor
The sensor must be placed so that the interior light
does not affect the sensor.
Possible placement could be in the front of the cooler
or at the top.
Door sensor
Danfoss does not supply the door-switch. Use the
door-switch you have and connect it to the cable
supplied by Danfoss.
