To Next PageTo Next PageWhat to do if the Danfoss Controller compressor does not start?
If the compressor does not start, it might be due to several reasons. It could be waiting for the compressor delay timer (check CoP->CSt), a defrost cycle in progress (check CoP ->Pot /Pod), or the line voltage to the compressor might be too low or too high (check dEF ->dit, dot). Also, check CoP->uLi, uLo, uHi.
Why does the Danfoss erc 112 display alternate between high and temperature?
The display alternates between high and temperature because the temperature is too high. Check ALA->HAt.
Why does the Danfoss Controller display alternate between condenser and temperature?
The display alternates between condenser and temperature because the condenser is too hot. Clean the condenser. Also, check Con ->CAL, CbL.
What does it mean when the Danfoss Controller display shows "dEf"?
When the display shows "dEf", it indicates that a defrost cycle is in progress. Check diS ->SdF.
Why does the Danfoss Controller display alternate between low and temperature?
The display alternates between low and temperature because the temperature is too low. Check ALA -> LAt.
Why is the Danfoss erc 112 display brightness weak?
The display brightness is weak because the ambient light sensor is broken. Replace the sensor.
How to fix shift between ECO and normal mode that does not happen on ambient light change on Danfoss Controller?
If the shift between ECO and normal mode does not happen on ambient light change, the ambient light sensor might be broken, or the light level is not set properly. Check Eng->SLd, SLn.
