Tech Note – Heat Pump COMP Error

In some situations the SV heat pump may go into a COMP error. This occurs when the compressor temperature has risen to a point where it is no longer safe for the unit to operate and it will turn off to protect itself from being damaged.

There are a few things that can be done to help alleviate this issue:

1. Ensure the filters are clean.

2. Remove any obstructions to the airflow generated by the heat pump fan.

3. Place Heat Pump into HEAT only mode to prevent cooling during the day when temperatures are expected to exceed 35°C
