Why does my Danfoss Controller display the wrong temperature?
The displayed temperature might be incorrect if the wrong type of sensor is selected. To resolve this, verify the sensor type setting by checking cFg ? o06.
What to do if the compressor does not start on my Danfoss ERC 21?
If the compressor fails to start, consider these potential causes: * The compressor delay timer might be active, so check c-- ?C02. * Defrost might be in progress, check d-- ? d03. * Line voltage to the compressor could be too low or too high, check A-- ? A72. Also check A-- ? A73 and A-- ? A75.
Why won't pull-down start on my Danfoss ERC 21 Controller?
Pull-down might not start if the pull-down max duration is set to 0, check r-- ? r96. Also, pull-down limit temperature might be too high, check r-- ? r97.
