PROBLEM
POSSIBLE CAUSE
SOLUTION
The DHW from the hot water taps is
too cold.
The DHW outlet temperature setting is too low.
Increase the DHW outlet temperature setting.
The mixer of the hot water tap is defective.
Check the DHW temperature at another hot water tap, since the mixer of the hot water tap in
question could be defective.
Incorrect connection of the circulation pump.
Check that the circulation pump is connected correctly.
The heat pump starts and stops before it
reaches the DHW temperature setting.
The air supply temperature is too low.
The air should be supplied from a room which is warm enough or use a different heat input
source for the heat pump.
The air ducts are too long or feature obstructions (like
risers or bends), or the air ducts and/or the evaporator
fins are clogged.
Adjust the length of the air ducts and the duct elbows as shown in the Operating Instructions,
clean the air ducts, and inspect the evaporator (and clean the fins as required).
The heat pump works continuously and
fails to reach the DHW temperature setting.
Heat is transferred from the DHW tank to the CH system.
Check the connections between the DHW tank and the boiler. Check valves should be installed
at the heat coil to prevent heat backflow from the DHW tank. If no check valves have been
installed, close the respective stop valves when the heat pump is used.
Heat loss from DHW circulation.
If the pump is wired to its controller, check and adjust the circulation mode settings. Reduce the
running time. The circulation pump is running when the icon flashes:
Check that the circulation pump is connected to an external source. If it is, you cannot control its
operation with the heat pump controller module.
The DHW is continuously taken off or taken off in
excessive volumes.
Check the DHW heating cycle if the DHW tank seems not to be providing DHW to the hot
water taps.
There is no DHW from the hot water taps.
The DHW supply has been cut off.
Check the cold water supply (the valves should be open) and its pressure in the plumbing.
The display is dark.
The wiring plug is not properly in the receptacle.
Check the plug.
Temperature sensor readings are not
displayed.
Incorrect wiring connections between the sensors and
the controller module.
Check the wiring connections (wiring plugs) in the back of the controller module.
Water is leaking.
The water system connections are leaking.
Seal the piping connections and check the connection ports of the unit.
The unit has been poorly levelled.
Check the level of the unit and that the condensate is properly drained.
The air ducts have no thermal insulation.
If cold air flows through the air duct, condensation of water can occur and the air ducts must be
provided with thermal insulation.
Incorrect routing of the condensate drain hose.
Install the hose with a drop away from the unit and connect its outlet to the sewer or a floor
drain. Check that the hose is not kinked and obstructing drainage.
The condensate drain hose is clogged.
Unclog the condensate drain hose.
The compressor is attempting to start with
an abnormal noise.
The compressor capacitor is defective, preventing the
compressor from running.
Contact the Customer Service. The capacitor must be replaced.
The heat pump is running with an
abnormal noise.
Foreign bodies obstruct the air flow through the unit.
Check that the evaporator fins are clean, the fan guard, and the air ducts.
The electric heater does not work.
The heater overtemperature protection has been tripped.
Check the overtemperature protection position under the front board. If the DHW tank is empty,
the overtemperature protection is tripped.
If the power cord is damaged, have it replaced with a dedicated power cord specified by the unit's manufacturer or with the power supply
kit, available from the manufacturer, by a professional repair centre.
