Compressor safety time for door switch: when the door is
opened the evaporator fans shut down and the compressor
doC
will continue working for time doC, after which it will shut
down.
Compressor restart time after door opening. when the
door is opened and after tdo time, it's setted back the normal

functioning giving door open alarm (Ed)
With tdo=0 the parameter is disabled.
FAN shutdown TEMPERATURE

SOLUTION

Check that cold room temperature sensor is
working properly

If the problem persists replace the sensor

Check that defrost sensor is working properly

If the problems persists replace the sensor

Switch unit off and back on

Reset the alarm input inside the cold room

Check that compressor is working properly

Check compressor absorption

If the problem persists contact the technical
assistance service

Check door switch status

Check door switch connections

If the problem persists contact the technical
assistance service

Check that the compressor is working properly.

