Charge pump lock Off/On On
The charge pump is only switched on once the HA
temperature has exceeded the tank temperature by 5K. It is
switched off when the HA temperature falls below the tank
temperature. This prevents cooling of the tank by the HA at
the beginning of water heating.

Pump parallel operation
HW partial priority: the heating circuits are locked during
water heating. The mixers close and the heating circuit
pumps switch off. The mixer circuits are enabled again once
the HA has reached the hot water target temperature + HA
target increase [HW temp. + HA HW temp.]. The mixer
circuits lock again if the HA temperature falls below the
enable temperature by the amount of the switching
hysteresis [HW hysteresis].
On => pump parallel operation: Only the direct heating
circuits are locked during water heating. The mixer circuits
continue to be heated. The water heating is extended with
this function.
Off => hot water priority mode: the heating circuits
are locked during water heating. The mixers close and
the heating circuit pumps switch off.
PPO all => pump parallel operation also for the direct
heating circuit: all heating circuits continue to be heated
during water heating. The water heating is extended with
this function. If the HA temperature exceeds the maximum
supply temperature of the direct heating circuit by 8K,
the heating circuit pump is of this circuit is switched off
(overheating protection). The heating circuit pump switches
on again if the HA temperature falls below the temperature
[maximum supply temperature + 5K].
HA HW temp. 0K - 50K 20K
Target increase during HW mode)
Heating appliance target temperature during water heating =
Hot water target temperature + HA HW temp.
The HA must be operated at an increased temperature
during water heating so that the hot water temperature in
the tank can be reached with the heat exchanger!
