Why does my Danfoss Controller display alternate between 'Hi' and temperature?
If the display alternates between 'Hi' and the temperature on your Danfoss Controller, it indicates that the temperature is too high. To address this, check the 'HAt' parameter under 'ALA'.
What to do if my Danfoss Controller display alternates between 'Lo' and temperature?
If the display alternates between 'Lo' and the temperature on your Danfoss Controller, it means the temperature is too low. Verify the 'LAt' parameter under 'ALA'.
Why does my Danfoss ERC 102 display alternate between 'Con' and temperature?
If the display alternates between 'Con' and the temperature on your Danfoss Controller, it indicates that the condenser is too hot. Begin by cleaning the condenser. If the problem persists, check 'CAL' and 'CbL' under 'Con'.
What to do if the compressor does not start on my Danfoss Controller?
If your Danfoss Controller's compressor isn't starting, it could be due to several reasons: * The compressor delay timer might be active: check 'CSt' under 'CoP'. * Defrost might be in progress: check 'Pot' or 'Pod' under 'CoP'. * The line voltage to the compressor could be too low or too high: check 'dit' and 'dot' under 'dEF'. * Also check 'uLi', 'uLo', 'uHi' under 'CoP'.
What does 'dEf' mean on my Danfoss ERC 102 Controller display?
If your Danfoss Controller displays 'dEf', it signifies that defrost is in progress. Check 'SdF' under 'diS'.
What does it mean if E01, E02, or E03 is shown on my Danfoss Controller display?
If your Danfoss Controller shows E01, E02, or E03, it means a sensor is defective: * E01: Sensor S1 is defective, replace the sensor. * E02: Sensor S2 is defective, replace the sensor. * E03: Sensor S3 is defective, replace the sensor.
Why doesn't the fan start on my Danfoss ERC 102 Controller?
If the fan on your Danfoss Controller isn't starting, it might be because the door is open or the door contact is defective. Ensure the door contact is working correctly.
Why doesn't defrost start on my Danfoss Controller?
If the defrost isn't starting on your Danfoss Controller, the controller might be in pull-down mode. Check the 'Pdi' parameter under 'Pud'.
Why doesn't the shift between Eco and Normal mode happen on ambient light change on my Danfoss ERC 102?
If the shift between Eco and Normal mode doesn't happen on ambient light change on your Danfoss Controller, the ambient light sensor might be broken, or the light level isn't set properly. Check 'SLd' and 'SLn' under 'Eng'.
Why doesn't the alarm sound on my Danfoss ERC 102 Controller?
If the alarm on your Danfoss Controller isn't sounding, it could be delayed. Check 'Htd' and 'Abd' under 'ALA'. Also, check 'Pdd' under 'Pud'.
