Menu 5.10
hysteresis for switching on the heat pump
This value is used to de
fi
ne by how much the heating circuit temperature
may drop below the calculated reference
fl
ow temperature. If the heating
circuit temperature drops below the reference
fl
ow temperature by the value
set here, then the heat pump, and if applicable the buffer charging pump,
are switched on.
Setting range: from -1°C to -10°C / default setting: -2°C
10.12 Domestic hot water min
Menu 5.12
minimum domestic hot water
temperature
If the set temperature in the domestic hot water storage tank is undershot
and the domestic hot water heating has been enable for this time, then
the heat pump and the storage tank charging pump switch on, as well as
the valve if applicable.
Setting range: from 10°C to 60°C / default setting: 45°C
10.13 Domestic hot water heating
Menu 5.13
The domestic hot water heating is switched off when the temperature in
the domestic hot water storage tank reaches the minimum domestic hot
water temperature plus the heating set here.
Setting range: from 2°C to 20°C / default setting: 10°C
10.14 Domestic hot water heating for low-rate period
Menu 5.14
do-
mestic hot water heating, low-rate period
With the value set here
it is possible, for example, to ensure greater do-
mestic hot water heating during the low-rate periods. T
he domestic hot
water heating is only switched off when the temperature in the domestic hot
water storage tank reaches the minimum domestic hot water temperature
plus the heating for low-rate period set here.
Setting range: from 0°C to 30°C / default setting: 0°C = off

hysteresis for switching off the
heat pump
This value is used to de
fi
ne by how much the heating circuit temperature
may exceed the calculated reference
fl
ow temperature. If the heating
circuit temperature exceeds the reference
fl
ow temperature by the value
set here, then the heat pump, and if applicable the buffer charging pump,
are switched off.
