Header temperature
The header temperature is the ow temperature in the header
downstream of the low loss header. The header temperature
therefore corresponds to the heating water temperature of heating
systems equipped with a gas red boiler.
Heating water temperature
The heating water temperature is the radiator ow temperature.
The higher the heating water temperature, the higher the heat
transfer to radiators.
Mixer circuit temperature
The mixer circuit temperature is the ow temperature downstream of
the mixer, with which underoor heating systems are supplied.
Cylinder heating
Heating up a DHW cylinder.
Heating program
Subject to program selection, the heating time program switches
from heating to economy mode or from heating mode to heating
OFF and vice versa.
Domestic hot water program
The DHW time program switches "Enable DHW cylinder heating"
ON and OFF.
Winter mode
Central heating and DHW according to the heating and DHW
time program.
Summer mode
Central heating OFF, DHW according to the DHW time program.
Heating mode / Setback mode
In winter mode, two heating water temperatures can be selected,
i.e. standard room temperature and setback temperature. In
the latter case the temperature will be reduced to the setback
temperature.
The heating program changes over between heating and setback
mode.
