These tips help you to take the first troubleshooting steps:
- any fault can be acknowledged. To do this, please keep the adjustment button of the heat pump control unit pressed for 10 seconds.
- If the measures described here do not help to correct the fault, please contact your local accredited installer.
First troubleshooting steps
All units except brine/water compact (23 kW and 33kW) and water/water compact (28 kW and 44 kW) Here you must check whether an additional heat generetar is installed.
3. Is the heating system vented?
If "gurgling" can be heard while the circulation pump is running, the heating system may need venting. The heat pump controller can be used to activate the circulation pumps individually to check their function.
To do this, go to Service > Settings > Vent system and set a tick next to the respective pump. The selected pump runs immediately following the confirmation.
1. Are the intake and discharge ducts/openings covered, blocked or grown over?
The intake and discharge openings of the heat pump must be clear so that the heat pump can "breathe" properly. Increased running costs (efficiency of the heating pump worsens) and faults can be avoided in this way.
2. Is the fan running?
If the fan is not running the heat pump cannot remove the cold air produced and the air heat exchanger (evaporator) freezes. The result is a low-pressure fault. The fan can be activated via the heat pump controller to check its function.
To do this, go to Service > Settings > Vent system and set a tick next to BOSUP fan. The fan runs immediately following the confirmation. It runs for the duration of the set time or can be ended manually by removing the tick next to BOSUP fan.
3. Does the outdoor temperature sensor display the correct temperature?
Check the plausibility of the displayed value. This should correspond to the current outdoor temperature and be roughly the same as the heat source inlet temperature.
You will find these values under Service > Information > Temperatures.
