The function full charging makes it possible that the released heat source is first
switched off, despite automatic heat source block if the buffer storage tank is
fully charged. During active function the heat source parameterized for the fully
charging function is first switched off, if the fully charging setpoint is reached or
the boiler must be switched off because of burner control.
Off: the Full charging function is switched off.
Heating Mode: The full charging is active if the automatic heat source block
blocks the heat source during valid heat request based on the buffer tempera-
ture. If the buffer storage tank reaches the requested temperature on the sensor
parameterized for the full charging function, the function is ended.
Always: The full charging is active if the automatic heat source block blocks the
heat source during valid heat request based on the buffer temperature or the
heat request is invalid. If the buffer storage tank reaches the requested tempera-
ture on the sensor parameterized for the full charging function, the function is
ended.
The buffer storage tank is charged minimally to the set value.
With B4 For the full charging function the buffer storage tank sensor B4 is consid-
ered.
With B42/B41: For the full charging function the buffer storage tank sensor B42,
if not available buffer storage tank sensor B41, is considered.

8.4.16 DHW-storage

The DHW release is pushed forward by the set charge push forward time com-
pared to each heating circuit allocation and kept during the heating circuit alloca-
tion.

DHW release
The boiler temperature setpoint for charging the DHW storage tank consists of
the DHW temperature setpoint and the flow setpoint boost.
Through the transfer, energy can be moved from the buffer storage tank into the
DHW storage tank. For this the current buffer storage tank temperature must be
higher than the current temperature in the DHW storage tank. This temperature
difference is set here.
