INFO
ROOM TEMPERATURE
ROOM TEMPERATURE HC1
°C
If an external programming unit is connected and assigned to the heating circuit, the temperature mea-
sured in the programming unit is displayed. If the heating circuit has no programming unit assigned,
the actual set room temperature is displayed as a substitute value.
SET ROOM TEMPERATURE HC1 °C
RELATIVE HUMIDITY HC1
%
If an external programming unit is connected and assigned to the heating circuit, the humidity measu-
red in the programming unit is displayed. If the heating circuit has no programming unit assigned, 0%
is displayed.
ROOM TEMPERATURE HC2
°C
If an external programming unit is connected and assigned to the heating circuit, the temperature mea-
sured in the programming unit is displayed. If the heating circuit has no programming unit assigned,
the actual set room temperature is displayed as a substitute value.
SET ROOM TEMPERATURE HC2 °C
RELATIVE HUMIDITY HC2
%
If an external programming unit is connected and assigned to the heating circuit, the humidity measu-
red in the programming unit is displayed. If the heating circuit has no programming unit assigned, 0%
is displayed.
HEATING
OUTSIDE TEMPERATURE °C
ACTUAL VALUE HC1
°C
Heating circuit temperature, calculated from the flow and return temperatures, weighted with the value
set under "FLOW PROPORTION". Whilst DHW is being heated, this parameter indicates the temperature
with which the DHW cylinder is being heated.
SET VALUE HC1 °C Default temperature for the heating circuit
ACTUAL VALUE HC2 °C
SET VALUE HC2 °C
FLOW TEMPERATURE
°C
The flow is the heating pipework between heat pump and heat consumer (radiator or indirect coil inside
the DHW cylinder). Here you can see the temperature of the water in this pipe section.
RETURN TEMPERATURE °C The return is the heating pipework between heat consumer and the heat pump. Here you can see the
temperature of the water in this pipe section.

DHW
DHW TEMPERATURE °C Shows the current cylinder water temperature
DHW 2 ACT. TEMP. °C If the „2ND DHW CYLINDER“ parameter is set to „ON“, the temperature in the second DHW cylinder is
shown here.

VENTILATION
SUPPLY AIR ACTUAL Hz Indicates the current supply air fan speed.
SUPPLY AIR SET
m³/h
This value indicates the percentage of maximum control voltage with which the supply air fan operates.
Supply air is the heated outdoor air that is blown into the ventilation area (living room, bedroom, nur-
sery).
EXTRACT AIR ACTUAL Hz Current speed of the extract air fan
EXTRACT AIR SET m³/h This value indicates the percentage of maximum control voltage with which the extract air fan operates.
Extract air is the stale air that is extracted from the extract air area (bathroom, kitchen, WC).
EXTRACT AIR HUMIDITY %
EXTRACT AIR TEMP. °C
EXTRACT AIR DEW POINT °C
DIFFERENTIAL PRESSURE ACTUAL Pa If the „FAN CONTROL“ parameter is set to „DIFFERENTIAL PRESSURE“, the differential pressure between
the extract air and the atmospheric pressure in the installation room is shown here.
