– Fault-induced shutdown
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).
– In addition, other errors/malfunctions can occur on
the unit or system.
10.2 Malfunctions of eBUS components
Fault code Error text/description Possible cause Solution
1 XXX address YY not accessible A component XXX connected via the
eBUS, e.g. VR 60 with the address YY
is not recognised. Check the eBUS cable and plug.
Check that the address switch is correctly set.
4 XXX address YY sensor fault ZZZ A sensor ZZZ on one of the compo-
nents XXX connected via the eBUS,
with the address YY, is defective.
Check the ProE plugs on the PCBs, check the sen-
sor for correct functioning, replace sensor.
5 XXXX setpoint not achieved XXXX setpoint not achieved. Check temperature setpoint.
Check position of temperature sensor.
Deactivate temperature error detection (C13).

10.3 Displays in the error memory and under
"Warning message"
The heat pump, including the compressor, remains in
operation. The following errors are displayed in the
error memory and in Menu 1 as warning messages.
Fault code Error text/description Possible cause Solution
26 Overheating on compressor
pressure side Excessively high output with a high
flow temperature. Reduce the heating curve. Check the required
heating output (floor drying, building shells) and
reduce if necessary.
36 Low brine pressure Pressure drop in the heat source sys-
tem as a result of leakage or air lock.
Pressure < 0.6 bar Check heat source system for leaks, top up brine,
bleed.

in Menu 1, no shut-down
10.4 Temporary shut-down
The compressor shuts down, the heat pump remains in
operation. The compressor can start again after 5 min-
utes at the soonest. (see below for exceptions).
Fault code Error text/description Possible cause Solution
20 Frost protection heat source
monitoring source outlet
Temperature difference at the
heat source (T3 - T8) > preset
value "Delta T. T3-T7"
This error message is deactivat-
ed as standard and can only be
activated via vrDIALOG parame-
ter "permitted temp. difference"
(20 K difference means deacti-
vated).
Heat source pump defective, temper-
ature sensor T8 or T3 defective.
Too low a volume flow in the heat
source circuit.
No/full dirt filter in source return line.
Air in brine circuit. Check heat source flow rate.
Check the plug contact on the PCB and the cable
harness, check the sensor for correct position
and function (resistance measurement using VR
11 characteristics, see Appendix), replace sensor.
Check the volume flow of the well pump/brine
pump (optimum temp. difference approx. 3-5 K).
Fit/clean dirt filter.
Bleed the brine circuit.
