9.2 Care
CAUTION
The surface of the heat pump can be damaged! The surface of the heat pump
can get damaged by using inappropriate cleaning agents. Do not use cleaning
agents which could damage plastic. The use of solvents and chlorinated
cleaning agents is prohibited. Use a wet towel and soap if necessary.
Clean the device with a non-abrasive wet towel and a mild soapy solution.
Do not use aggressive cleaning agents, solvents or chlorinated cleaning agents.
10 Disturbances in the operation
10.1 Warnings
WARNINGS
CAUSE
SOLUTION
A1
Shut-down of HP
because of low
intake air
temperature.
The room must be vented to raise the air temperature above the lower limit.
Set the shut-down temperature to a lower value.
CAUTION: FREEZING OF
THE EVAPORATOR CAN OCCUR WITH SHUT-DOWN TEMPERATURES
LOWER THAN -10 °C. LOWER VALUES CAN BE USED ONLY IN CASE
OF VERY LOW RELATIVE MOISTURE (UNDER 35°C).
If the HP is connected to a DHW, the programme must be set to P2 or P4.
The programme P2 will only heat water with the DHW, programme P4 will
heat the water with the HP (when the environmental conditions are suitable)
and DHW.
A3
Shut-down of HP
because of high
intake air
temperature
(40°C)
The room must be vented to lower the air temperature below the upper limit.
If the temperature of the intake air is constantly above the upper limit, another
room must be found for setting up the HP or the air ducts have to be routed
into the room with a temperature lower than the upper level (40°C).
10.2 Disruptions
ERRORS
CAUSE
SOLUTION
E7
High pressure in the
cooling system.
Check whether the buffer tank has enough water.
You can erase the error by pressing the + key. If the error
persists, contact the service.
Alternately
E8
and
¯ ¯
The sensor for DHW is
not connected.
Check whether the sensor is connected. If not, contact the
service.
Alternately
E8
and
_ _
Malfunction of the
temperature sensor for
DHW.
First, turn off the heat pump and reconnect it to the mains.
Check the connection and the cable of the cable. If the error
persists, contact the service.
Alternately
E9
and ¯ ¯
The air sensor is not
connected.
Check whether the sensor is connected. If not, contact the
service.
Alternately
E9
and
_ _
Air sensor malfunction.
First, turn off the heat pump and reconnect it to the mains.
Check the connection and the cable of the cable. If the error
persists, contact the service.
DESCRIPTION OF
THE ERROR
CAUSE
SOLUTION
Water does not heat to
the set temperature.
The DHW circuit is
closed.
Restore the correct circuit.
Circulation withdraws a lot
of heat.
Turn off the circulation pump and close the valve.
The cooling system is
leaking.
Contact the service
Damaged evaporator due
to inattentive cleaning.
Contact the service
Not enough gas in the
system.
Contact the service.
