OPERATION
Troubleshooting
Problem Cause
The appliance reduces the
set value temporarily to the
current actual value on the in-
tegral sensor subject to the in-
take temperature and the hot
gas temperature, as required.
The air intake temperature
exceeds the upper application
limit (see "Specification / Data
table" chapter). The appli-
ance safety equipment has
responded and the appliance
has switched off automatically.
The air intake temperature
falls below the lower applica-
tion limit (see "Specification /
Data table" chapter). The
evaporator is being defrosted
intermittently.
The appliance output data are
calculated according to stand-
ard, using the intake temper-
ature specified in the data
table. Below this temperature
the appliance efficiency and
output decrease. The heat-up
time is extended.
If the water does not heat up
or the heat pump runtime is
very long, this may be due to
an excessively low intake tem-
perature.
The appliance The compressor lockout time

The condensate The surface temperature of

the dew point temperature of
the ambient air. Condensate
forms.
The room tem-
perature drops
too low.
High power The lower the intake tempera-
consumption ture, the lower the heat pump
efficiency.
Runtime-dependent rapid
heat-up is activated.

Remedy
No action required. The ap-
pliance displays the "Set tem-
perature adjustment" symbol
and blocks DHW heating until
the actual temperature cap-
tured by the integral sensor is
6 K below the temporary set
temperature. DHW heating is
then re-enabled and the orig-
inally selected set tempera-
ture is again applied.
Wait for the appliance to cool
down. Call a qualified con-
tractor if the appliance does
not restart automatically.
Wait until the appliance re-
starts automatically.
Use runtime-dependent rapid
heat-up if necessary.
No action required. Use runt-
ime-dependent rapid heat-up
if necessary.
No action required.
Notify a qualified contractor if
water continues to drip when
heat-up has been completed.
The amount of condensate
depends on the humidity
level of the ambient air.
Operation of the appliance
can cause the room temper-
ature to fall by 1 to 3 °C. If
the room temperature falls
by more than 5 °C, check the
room size (see the "Specifi-
cation / Data table" chapter).
Increasing the room size by
opening a door to another
room will remedy this.
Avoid low intake tempera-
tures if at all possible.
Only activate this function if
really necessary or increase
the runtime during which the
heat pump operates alone
and the electric emergency/
booster heater is blocked via
your selected parameters.

turned fully clockwise. Have a
qualified contractor check the
