INSTALLATION
Commissioning
appliance will use this to calculate the optimum value for heat
pump operation.
Please note that setting too high a heat demand here will reduce
the efficiency of the whole system. Conversely, setting too low a
heat demand can lead to reduced comfort.
DESIGN TEMPERATURE
Select the design temperature here. This will be the outside tem-
perature (°C) for which heat demand was calculated, in the region
where the heat pump is being used.
HEAT DEMAND
Select the heat demand calculated for the design temperature
here.
CONSTANT OUTPUT
This parameter determines the heating output in fixed value and
swimming pool operation and in the heat-up program. The output
is then controlled to the permanently set output, irrespective of
the outside temperature.
CONDENSATE RIBBON HEATER
At an outside temperature below 3 °C, the ribbon heater switches
on.
OUTSIDE TEMPERATURE
Select the outside temperature here.
SINGLE PHASE OPERATION
ON / OFF
QUICK START
During commissioning, you can test the heat pump function by
triggering a heat pump quick start. When calling up parameters,
OFF is shown on the display. If you set it to ON and press OK, a
quick start is initiated. The relevant pumps are switched on after
the start. The value on the display visibly counts down from 60 to
0 s. On quick start the display then shows ON.
After that, the heat pump and the associated buffer charging pump
are switched on.
11.1.7 SILENT MODE
Reduced noise mode
SILENT MODE is an operating mode for air source heat pumps in
which the sound level of the heat pump is reduced.
Note
Silent mode has an effect on the heating output and ef-
ficiency of the heat pump.
When silent mode 2 is active, higher electricity bills re-
sult.
FAN REDUCTION
As soon as this parameter is set to ON while SILENT PROGRAM 1
is enabled, the fan speed of type 1/1* and type 4/4* heat pumps
is reduced.
OUTPUT REDUCTION
As soon as this parameter is set to ON while SILENT PROGRAM 1
is enabled, the fan speed and compressor output of type 3/3* and
5/5* heat pumps can be reduced independently of each other with
the following parameters.
OUTPUT
The reduction in the compressor output can be set here in %.
FAN
The reduction in the fan speed can be set here in %.
HEAT PUMP OFF
As soon as this parameter is set to ON while SILENT PROGRAM 2 is
enabled, the heat pump is switched off and the internal or external
heat source 2 takes over the DHW / central heating function.
11.1.8 EMERGENCY OPERATION
Characteristics when "Fatal Error" fault occurs in conjunction with
emergency operation:
The EMERGENCY OPERATION parameter can be set to ON or OFF.
Emergency operation set to ON:
As soon as a Fatal Error occurs in heat pump types with internal
electric reheating and the heat pump fails, the operating mode
automatically switches over into emergency operation.
Every heat pump in a cascade must suffer a fatal error before
the program switch automatically switches over to emergency
operation.
There’s one exception: Automatic emergency operation will also
be triggered if only the preselected heat pump for DHW fails.
In heat pump types with external heat source, heat source 2 must
be set to ON for central heating or DHW heating; only then can it
automatically change over to emergency operation when a fatal
error occurs.
Emergency operation set to OFF:
As soon as faults occur in HP types with internal electric reheating
and the heat pump fails, heat source 2 for central heating takes
over frost protection.
11.1.9 HEAT PUMP RESET
If a fault occurs the heat pump can be reset. Setting it to ON clears
the fault that has occurred. The compressor starts again. The fault
remains stored in the fault list.
11.1.10 FAULT LIST RESET
ON / OFF
The entire fault list is deleted.
11.1.11 SYSTEM RESET
A system reset will reset the heat pump manager to its delivered
condition (factory settings).
