MINIMUM RUNTIME
Each time the compressor is switched on, a countdown starts
using the selected time (in minutes). The controller can only stop
the compressor after this time has elapsed, i.e. controller shut-
down can be delayed. One exception is a response by the temper-
ature limiter or pressure switch, which results in an immediate
shutdown.
POWERDEFROST
Power defrost is an extension of the standard defrost process.
During intensive defrost, hot air is routed through the fan nozzle.
In this parameter, you can select how often intensive defrost is
carried out instead of the standard defrost process.
Example: If the parameter is set to "5", every fifth defrost is a
power defrost.
Note
During an intensive defrost, higher operating costs may
be incurred.
HEATING SYSTEM SIZING
The heat demand for the house is set here, taking into consider-
ation the lowest regional temperatures (for example 10kW heat
demand at -14°C outside temperature). During operation, the
device will use this to calculate the optimum value for heat pump
operation.
Refer to the building's heat demand calculation to determine
the values.
Please note that if a higher heat demand is set, the efficiency of the
overall system will reduce. On the other hand, if the heat demand
is set too low, a degree of comfort may be lost.
DESIGN TEMPERATURE
Select the design temperature here. This will be the outside
temperature (°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 tempera-
ture here.
CONSTANT OUTPUT
This parameter determines the heating output as a fixed value, for
swimming pool operation and the heat-up program. The output
is then controlled to the permanently set output, irrespective of
the outside temperature.
CONDENSATE RIBBON HEATER
The condensate ribbon heater ensures that condensate can drain
away even at low outside temperatures.
OUTSIDE TEMPERATURE
Set here the outside temperature above which the conden-
sate ribbon heater is switched on.
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 value on the display visibly counts down
from 60 to 0s. On quick start the display then shows ON.
After that, the heat pump and the associated buffer charging pump
are switched on.
SILENT MODE
Reduced noise mode
SILENT MODE is an operating mode for air/water 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 is active, operating costs will be higher.
In silent mode 2, heating and DHW heating are provided
solely via the emergency/booster heater.
In the "PROGRAMS/ SILENT PROGRAM1" menu, set the
times when the heat pump should switch to a quieter oper-
ating mode.
FAN REDUCTION
As soon as this parameter is set to ON, while SILENT PROGRAM 1
is enabled, the fan speed of the 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 the compressor output of the heat
pump can be reduced independently of each other by means of
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
second heat source takes over the DHW/ Central heating function.
POWER-OFF
During a tariff blocking time by the power supply utility, the heat
pump cannot meet a heat demand. With this parameter, you can
specify the characteristics of the heat pump and the internal re-
heating stages during a tariff blocking time.
