NOTE
Heating request
A heating request is present if the "Return set temperature" minus the
"Hysteresis return set temperature" is higher than the current measured
"Return temperature".
Display of sensor and system values
Display of outside air and supply air temperature
Display of exhaust air and extract air temperature
Display speed supply air fan
Display speed exhaust air fan
Displays the temperature measured by the frost protection sensor cooling.
Displays the temperature measured by the hot gas sensor (R18)
Indicates whether a request for domestic hot water has been made. Even if a request
is pending, it is possible that the heat pump still does not operate (e.g. programmed
shut-off times, operating limits, heating up). This block is shown by the preceding lock

symbol .
Displays the current domestic hot water set temperature.
Displays the measured hot water temperature (R3).
Display of the current maximum domestic hot water temperature for the 1 compressor
operation
Display of the current maximum domestic hot water temperature for the 2 compressor
operation
Indicates whether a request for swimming pool water is pending. Even if a request is
pending, it is possible that the heat pump still does not operate (e.g. programmed
shut-off times, operating limits, heating up). This block is shown by the preceding lock

symbol .
Displays the current swimming pool set temperature.
Displays the current swimming pool temperature (R20).
Displays the heat source temperature (R27).
Displays the temperature measured at the outlet of the heat source (R6).
Displays the current pressure (R26) on the high pressure side.
Displays the current pressure (R25) on the low pressure side.
Displays the heat source temperature (R24) for systems with a combination of
passive cooling and a reversible heat pump.
Displays the heat pump type identified from the coding resistor (R7).
Displays the heating controller software version including the boot and bios version,
as well as the valid network address.
Displays which extension modules are available.
