This function allows you to set the area installed in collector array 1. The solar yield is
only displayed if an area > 0 m
Use of flat-plate collectors in collector array 1
Use of evacuated tube collectors in collector array 1
Climate zone of the installation location according to the map ( Fig. 24, page 206).
▶ Search for the location of the system on the climate zones map and set the climate
zone number.
DHW reheating via the heat appliance irrespective of the minimum DHW temperature
amount of heat is sufficient to supply DHW. The control system then reduces the set
DHW temperature to be produced by the heat appliance in accordance with these two
values. If there is sufficient solar yield, there is therefore no need to reheat the DHW
with the heat appliance. If the temperature set here is not reached, the DHW is
reheated by the heat appliance.
Solar influence switched off.
Influence of solar on the set room temperature: at a high value, the flow temperature of
the heating curve is reduced at a correspondingly greater rate in order to enable
greater passive solar energy input through the building's windows. At the same time
this reduces a temperature overshoot in the building and increases the comfort level.
• Increase Solar infl. heat. circ. 1 ( – 5 K = max. influence) if the heating circuit heats
rooms that have large south-facing windows.
• Do not increase Solar infl. heat. circ. 1 if the heating circuit heats rooms that have
small north-facing windows.
Resets the solar yield to zero.
Resets the solar optimisation calibration and restarts it. The settings for Solar yield/
optimisation remain unchanged.

In order to obtain accurate readings from the heat meter, the glycol content of the heat
transfer fluid must be specified.
