Emergency operation after a fault with consequent per-
manent switch-off (manual)
In the event of a permanent switch-off due to a fault, emer-
gency operation can be enabled manually using the auxil-
iary heater (
¬
Ch. 11.5
). The following parameters are shown
in the display under the fault message”Low pressure
switch-off”:
– Reset (YES/NO)
YES removes the fault message and enables compressor
operation.
– DHW priority (YES/NO)
YES enables the auxiliary heater for hot water handling.
– CH priority (YES/NO)
YES enables the auxiliary heater for central heating.

Settable functions at code level
Floor drying
This function can be used to heat dry a newly laid floors
(
¬
Tab.
9.1
). The flow temperature corresponds to a routine
stored in the controller and is independent of the outside
temperature. When the function is enabled, all selected
operation modes are interrupted (
Menu C6
) (
¬
Tab. 9.6
).

Floor drying procedure
The operating mode is displayed together with the current
day and the target inlet temperature. The current day can
be set manually.
If the
brine circuit/heat source circuit has not yet been
completed
, the floor can be dried using the auxiliary heater.
>
To do this, select the value “
Aux. heating only
” for the
parameter “Aux on during CH” in the Menu C7 “Auxiliary
heater”(
¬
Tab. 9.6
).
b
Caution:
Possible overloading of the heat source
due to excessive energy consumption.
During floor drying (e. g. in the winter
months), the heat source may be over-
loaded and its regeneration may be
degraded as a result.
>
When outside temperatures are low, ena-
ble an external auxiliary heater for floor
drying.
When the function is started, the current time of the start
is saved. The day is changed exactly at this time.
After network-off/-on, the floor-drying begins as follows:
