Solar yield/optimisation
The gross collector area, collector version and climate zone
number must be set correctly in order to achieve maximum
energy savings.
The solar yield displayed is a calculated yield estimate.
Measured values are displayed with the function heat meter (L)
(Accessories WMZ).

temperature
15 ... 45 ... 70 °C: The control system
determines whether solar yield is available
and whether the stored 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 energy yield, there is
therefore no need to reheat the DHW with
the heat generator. If the temperature set
here is not reached, the DHW is reheated by
the heat generator.

achieve 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.

Glycol content 0 ... 45 ... 50 %: to obtain accurate readings
from the heat meter, the glycol content of the
