6.3. Non-standard conditions and faults
If the system registers some non-standard condition or fault, the controller is informed. The
information is shown on the controller display and at the same time, it is available via the
controller website. If set, the controller sends an email message about the problem. For more
information, please refer to the manual of the respective controller.
The selected fault conditions (e.g. compressor overcurrent, high/low refrigerant pressure,
defrosting fault or insufficient heating water flow) will be reset after 10 minutes. If the alarm
repeats 3 times in a row, the compressor will shut down permanently.
If a fault occurs, you should always contact the installation company that installed your system
with the heat pump. In the communication with your installer or heat pump supplier, always
report the serial number of the heat pump (indicated on the heat pump label and in the Heat
Pump Commissioning Protocol).
Unusual phenomena
If any unusual phenomenon occurs, especially if there is sparking in the wiring, odour or
smoke leakage, then switch off the appliance without delay and call an authorised service
centre.
Normal phenomenon – evaporator defrosting
The fan stops during the defrosting cycle, but the compressor is still running. Melted ice flows
into the condensate tray under the heat pump. As soon as defrosting is completed, the fan
starts up again and a cloud of fumes formed by moist air may form for a short time. This is a
perfectly normal phenomenon that disappears after a few seconds.
On frosty days, check for ice in unusual places (heat pump legs, condensate tray, fan, etc.).
Possible causes can be: blocked condensate drain piping (e.g. when condensate freezes
inside the piping), lack of refrigerant or extreme weather conditions.
