Why won't my Danfoss ERC 214 Controller's compressor start?
Several factors can prevent the compressor from starting. It may be waiting for the compressor delay timer; in this case, check parameter C02. A defrost cycle might be in progress, so check parameters d03 and d19. Also, the line voltage to the compressor could be too low or too high; verify parameters A72, A73, and A75.
What to do if the Danfoss Controller displays the wrong temperature?
If the temperature displayed is incorrect, the wrong type of sensor might be selected. Verify the sensor type by checking parameter o06 in the cFg menu.
Why does defrost not start on my Danfoss ERC 214 Controller?
If the defrost cycle isn't starting, the controller might be in pull-down mode. Check parameter r96 to confirm.
Why does my Danfoss ERC 214 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 214 Controller?
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 214 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.
How to troubleshoot a Danfoss ERC 214 when pull-down does not start?
If the pull-down function isn't initiating, it could be due to the pull-down maximum duration being set to 0, or the pull-down limit temperature being set too high. Check parameters r96 and r97 to adjust these settings.
