Excess reaction
Coordination of the heat drawn off in
the secondary circuit when the heat
pump produces an excess of heat or
the heat drawn by the secondary cir-
cuit is suddenly choked off.
Settings:
0 No heat drawn off
1 Heat will be drawn off only in case
of critical excess, i.e. if critical tem-
peratures were reached in the heat
pump circuit or the minimum heat
pump runtime has not yet been
reached.
2 Heat will be drawn off, even if the
excess heat being created is not
critical for the heat pump.

Second temperature sensor
The DHW buffer cylinder can be
equipped with a second temperature
sensor in the lower area for switching
heating OFF.
For this, select the "
Yes " setting.
Without this sensor heating is
switched OFF subject to the return
temperature.
In that case, select "
No " for this set-
ting.
