The boiler parallel shift of the tank loading pump (parameter) acts on the mixed heating circuit demand.

The boiler parallel shift of mixed heating circuits acts on the heat generator, provided the tank loading pump control mode has not been set to "external storage tank".

The optional return flow limit acts on the flow mixture according to the setting.

The hot-water pre-control acts only on hot-water loading configured in the same device.

7.2.6Mode of operation: Hot-water pre-control

When operating in combination with hot-water pre-control, parameter 08 (tank drainage protection) does not act directly on the heat generator, but on the hot-water pre-control.

Parameter 08 is always adjustable for function with pre-mixer. Here, the "OFF" and "ON" settings have different effects, which are described in the following.

Function With the setting "OFF", there will be no start-up protection through the hot-water pre-control. The tank loading pump is switched on without any delay.

With the setting "ON", the tank loading pump is switched on only when the flow sensor detects that the hot-water setpoint temperature + ½ switching difference hot water (without offset) is reached:

•HWPCsetpoint = WHsetpoint + P09(HW)

•SLP = ON if HWPCactual ≥ HWsetpoin t + 12 SDHW

•SLP = OFF if HWPCactual ≤ HWsetpoint
