Table 81 Extra hot water stop temperature
▶ Set the stop temperature for extra hot water.
Additional amount of hot water is produced by temporarily increasing
the temperature of the hot water during the set number of hours to the
indicated stop temperature.
The heat pump starts the function directly and uses the compressor first
and then the additional heat source to increase the temperature. When
the desired number of hours have passed, the heat pump returns to
normal hot water mode.
DANGER: Risk of burn injuries.
▶ Use a mixing valve when the hot water temperature
exceeds 60 °C.
> Hot water peak
Hot water peak means a temporary increase in the hot water
temperature to approx. 65 °C for thermal elimination of bacteria
(pasteurisation).
The Hot water circulation pump is controlled by the control unit during
the hot water peak.
For the hot water temperature increase, the compressor is used first;
the additional heat source then continues alone.

The hot water peak is activated on the selected day and at the selected
time. It continues until the stop temperature has been reached plus
the time for warm-keeping (duration of hot water peak). The hot water
peak cannot continue longer than the set Maximum time. If it is
cancelled because the maximum time has expired, a message is
shown in the display and a new attempt is made after 24 hours.
> Hot water program
Program 1 and Program 2 enables you to block hot water production
during the set time.
