Domestic hot water Yes
Flange heater No
Swimming pool No
Note:
The possible domestic hot water
temperatures depend largely on
the design of the combo tank.
On combo tanks without a sepa-
rating plate, the additional buffer
tank (3) guarantees the defrost-
ing function with air-to-water
heat pumps.
A sensor in the bottom section of
the combo tank blocks the heat
pump when it is fully loaded and
activates the mixer regulation.
The water in the combo tank is
heated by solar energy and is
also used for supplementary
heating (see also Chapt. 8.11.3
on page 111).
Heating, domestic hot water and swimming pool water preparation
Pre-configuration
Setting

Order of priority:
Domestic hot water preparation
has priority over heating and
swimming pool preparation (see
Chapt. 8.12 on page 111)
A request for swimming pool
water comes in via input ID2.
