10.5 Blocking error
The heat pump is shut down. It can only be restarted by
resetting the error after removing the cause of the fault
(see Menu I 1).
With the exception of Errors 90 and 91, these do not
need to be reset. The heat pump starts again when the
cause of the error has been removed.
Emergency mode
Depending on the nature of the malfunction, there are
settings that can be made to allow the heat pump to
continue operating in an emergency mode (by means of
the integrated electrical heating) until the fault is
cleared, either in heating operation (display: "CH priori-
ty"), hot water operation (display: "DHW priority") or
both (display: "CH priority/DHW priority"), see the fol-
lowing tables, "Emergency operation" column.

mode
Possible cause Solution
32 Error heat source sensor T8
Short-circuit in the sensor possible The internal sensor for the source out-
let temperature is defective or not
properly plugged into the PCB. Check the plug contact on the PCB
and the cable harness, check the
sensor for correct position and func-
tion (resistance measurement using
VR 11 characteristics, see Appendix),
replace sensor.
33 Error heat circuit pressure sensor
short-circuit in the pressure sensor
The pressure sensor in the heating cir-
cuit is defective or not properly
plugged in.
Check the plug contact on the PCB
and the cable harness, check pres-
sure sensor for correct functioning,
replace pressure sensor.
34 Error brine pressure sensor
short-circuit in the pressure sensor
possible The pressure sensor in the heat source
circuit is defective or not properly
plugged in.
40 Error comp outlet sensorT1
Short-circuit in the sensor
possible The internal temperature sensor on
the high pressure side of the compres-
sor is defective or not properly
plugged into the PCB.
Check the plug contact on the PCB
and the cable harness, check the
sensor for correct position and func-
tion (resistance measurement using
VR 11 characteristics, see Appendix),
replace sensor.
41 Error heat source sensor T3
Short-circuit in the sensor
possible The internal sensor for the source inlet
temperature is defective or not proper-
ly plugged into the PCB.
42 Error HP return sensor T5
Short-circuit in the sensor
possible The internal temperature sensor on
the heating return line is defective or
not properly plugged into the PCB.
43 Error HP flow sensor T6
Short-circuit in the sensor
possible The internal temperature sensor on
the heating flow line is defective or not
properly plugged into the PCB.
44 Error external sensor AF
Short-circuit in the sensor
possible The outside temperature sensor or its
connecting cable is defective or it is
not connected correctly. Check the ProE plug on the PCB,
check the connecting cable, replace
the sensor.
45 Error DHW tank sensor SP
Short-circuit in the sensor
possible The cylinder temperature sensor is de-
fective or it is not connected correctly.
Check the ProE plug on the PCB,
check the sensor for correct function
(resistance measurement using VR
10 characteristics, see Appendix), re-
place sensor. 46 Error HB flow sensor VF1
Short-circuit in the sensor
possible The upper sensor in the buffer cylinder
is defective or it is not connected cor-
rectly.
47 Error HB return sensor RF1
Short-circuit in the sensor
possible The lower sensor in the buffer cylinder
is defective or it is not connected cor-
rectly.
48 Error flow sensor VF2
Short-circuit in the sensor
WW opera-
tion possi-
ble The contact temperature sensor VF2 in
the heating circuit is defective or it is
not connected correctly.
52 Sensors are not suited to the hy-
draulic plan _ Hydraulic plan not entered correctly,
sensors not connected correctly. Check the hydraulic plan and sensor
positions using the existing system.
