9.3 Troubleshooting
If the split heat pump is experiencing problems during opera-
tion or is not working at all, check the following points.
CAUTION!
!!
Before opening the device, ensure that all electric circuits are
disconnected from the power supply.
9.3.1 Removing faults during operation
CAUTION!
!!
When filling the system, ensure that only the specified
refrigerant is used.
CAUTION!
!!
When filling the system, please note the filling quantity of the
system. If the pipeline is extended, a modified filling quantity
may be required.
CAUTION!
!!
The installation of piping should be restricted to the minimum
possible.
CAUTION!
!!
Always wear adequate personal protective equipment
(protective gloves, safety glasses, etc.) when working with
refrigerant.
CAUTION!
!!
Work involving R32 refrigerant must only be carried out by
experienced and adequately trained personnel.
CAUTION!
!!
Only equipment and tools intended for the product, pressure
and temperatures may be used for work on the device.
CAUTION!
!!
When checking for leaks, do not expose the device to a
pressure higher than the maximum pressure declared on the
type plate.
Pos. Fault
Cause Solution
1
Insufficient heating
or cooling.
Incorrect setting of the
target temperature.

Check the setting of the heating curve on the heat pump manager
Insufficient
water filling.

Check the pressure gauge and add water until the pressure gauge shows a
pressure of 2.0 to 2.5 bar.
Water flow is low.

Check whether the dirt trap is heavily soiled. If so, the dirt trap must be
cleaned.

Check whether the pressure indicator shows a pressure of at least 0.3 bar.

Check whether the water piping is blocked by soiling or limescale deposits.
2
The outdoor unit is
not working, despite correct
Power supply
(information on the
control panel).
Temperature on the
water inlet is too high.

If there is a temperature above 55 °C on the water inlet, the outdoor unit is
switched off to protect the system.
Temperature on the
water inlet is too
low.

If there is a temperature below 5 °C on the water inlet, the outdoor unit is
switched off to protect the system. Wait until the temperature on the water inlet
has been increased by the indoor unit.
3
Noises from the
water pump
Purging has not been
completed.

Open the protective cap of the purging fitting and add water until the pressure
gauge shows a pressure of 2.0 to 2.5 bar.

If no water comes out after pressing on the tip (on the top side of the opening),
the purging process is not yet complete. If the system has been purged opti-
mally, water sprays out like a fountain when pressing on the tip.
Water pressure is low.

Check whether the pressure indicator shows a pressure of at least 0.3
bar.

Check whether the equalising tank and pressure gauge are working correctly.
4
Water is drained off
through the
drain hose.
Too much water has been
added.

Open the lever of the safety valve and drain off more water until the pressure
gauge shows a pressure of 2.0 to 2.5 bar.
Equalising tank is dam-
aged.

Replace the equalising tank.
5
Domestic water is not
heated
Thermal circuit breaker
of the flange heater
or pipe heater has been
triggered

Open the front cover of the indoor component and press the Reset button
Domestic water heating
was deactivated.

Check the settings on the heat pump manager on the indoor unit.
