Problem
- The heat pump shows fault H1 / N1 or flashing sun symbol
Applies to
- Air - air heat pump
Resolution
1. The code means that the defrost function is active.
- The function runs to keep external components free of ice, and each program lasts approx. 4 - 8 minutes.
- The frequency varies depending on the outdoor temperature.
- The colder it is outside, the more often this function is activated.
2. While the function is on, the room is not heated.
This is normal behaviour and not a fault of the appliance.
