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. 

 

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. 

 

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:
