For the optional domestic hot water cylinder and the
optional circulation circuit, the operation modes "Auto",
"On" and "Off" are possible.
Auto: The hot water generator and circulation pump
become active after separately adjustable time pro-
grammes (¬ section 4.11.4)
On: Continuous hot water reheating, circulation pump runs
continuously.
Off: No DHW loading, frost protection function is active.
Max. hot water temperature: The maximum hot water
temperature determines the maximum temperature to
which the domestic hot water cylinder should be
heated.

an external auxiliary heater, the maximum hot
water temperature is limited by the pressure
sensor control shut-off in the coolant circuit and
cannot be adjusted!
Min. hot water temperature: The minimum hot water tem-
perature determines the limit below which the domes-
tic hot water cylinder is heated.
