8.2 Operating Data
All current operating statuses are displayed in the “Operating
data” menu item.
You can access the operating data menu by:
Pressing the button (MENUE) for approx. 5 seconds
Selecting the operating data menu item with the arrow
buttons and confirming with the ENTER button
Depending on the system configuration, the following data can
be queried in the “Operating data” menu:
Display of sensor and system values Display
The external temperature is used for calculating the return set
temperature, for antifreeze functions and for defrosting
At all times
Displays the calculated return set temperature for heating circuit 1 Not with silent
cooling only with
reversible HP
Displays the return temperature of heating circuit 1 measured on
the sensor. This temperature is the controlled variable for heating
circuit 1.
At all times
Displays the flow temperature measured on the sensor. This
temperature is used for antifreeze functions and for safeguarding
defrosting.
Air HP or sensor
connected
Displays the calculated set temperature for heating circuit 2 Heating circuit 2
Heating operation
Displays the minimum temperature possible with silent cooling,
calculated from the dew point plus dew point distance
Cooling operation
Silent cooling
only, reversible
HP
or HC2
Displays the temperature of heating circuit 2 measured on the
sensor.
This temperature is, among other things, the controlled variable for
heating circuit 2.
HC2 or
cooling operating
with silent cooling
only with
reversible HP
Displays the calculated set temperature for heating circuit 3 Heating circuit 3
Heating operation
Displays the temperature of heating circuit 3 measured on the
sensor. This temperature is the controlled variable for heating
circuit 3.
Heating circuit 3
Heating operation
Indicates if a request for heating has been made. Even if there is a
request for heating, it is possible that the heat pump will not
operate (e.g. because of the utility company shut-off time).
“Heating system flushing” is displayed when the system is being
flushed.
An HP block combined with a sufficiently high cylinder temperature
is indicated by “Bivalent-regen.”.
Min. 1 heating
circuit
Indicates which heat generator is available to carry out the heating
request
1: max. 1 compressor, 2: max. 2 compressors, 3: max. 2
compressors and a 2nd heat generator
Heating operation
Sensor for determining the defrost end with hot gas defrosting Air HP with hot
gas defrosting
Displays the temperature measured in the cylinder in bivalent-
regenerative systems
Bivalent-
regenerative
Displays the measured return temperature during cooling
operation measured at the heat exchanger input

function
Cooling operation
Displays the measured flow temperature during cooling operation
measured at the heat exchanger output
