Possible causes and solutions

The temperature of a cooler condenser is higher than the high temperature limit. As a result, the SCS Controller switches off the compressor to protect the asset.

  1. Check that nothing is blocking the condenser e.g. boxes
  2. Then reset by power cycling. 

If this fault continues to happen, check that the condenser fan is functioning correctly.
