7. Troubleshooting

7.1 High pressure switch

The high pressure switch protects the heat pump from excessive pressure in the refrigerant circuit. In the event of disturbances, the high pressure switch will stop the compressor. The system will restart when the high pressure switch is reset manually.

Before unscrewing the front cover, turn off the power to the system.

Take off the front cover by removing the screws.

Press the red button for RESET.
