the requested temperature at the sensor parameterized for the full
charging function, the function is ended.
Full charging temp min (4811)
The buffer storage tank is charged minimally o the set value.
Full charging sensor (4813)
With B4: For the full charging function the buffer storage tank sensor B4
is considered.
With B42/B41: For the full charging function the buffer storage tank sen
sor B42, if not available buffer storage tank sensor B41, is considered.

Forward shift charging (5011)
H Heating program
M Several times during the day
T DHW release
The DHW release is pushed forward by the set charge push forward time
compared to each heating circuit allocation and kept during the heating cir
cuit allocation.
Flow setpoint boost (5020)
The boiler temperature setpoint for charging the DHW storage tank con
sists of the DHW temperature setpoint and the flow setpoint boost.
Transfer boost (5021)
Through the transfer, energy can be moved from the buffer storage tank
into the DHW storage tank. For this the current buffer storage tank temper
ature must be higher than the current temperature in the DHW storage
tank. This temperature difference is set here.
Type of charging (5022)
Charging a stratification cylinder (if available):
Recharging : The cylinder is only recharged at every DHW demand.
Full charging: The cylinder is fully charged at every DHW demand.
Full charging legio: The cylinder is fully charged if the legionella function
is enabled; otherwise it is only recharged.
Full charg 1st time day: During the first charging of the day, the cylinder
is fully charged, then recharged.
Full charg 1st time legio: The cylinder is fully charged during the first
charging of the day and if the legionella function is enabled; otherwise it
is recharged
Explanations:
Full charging: The stratification cylinder is fully charged. The heat de
mand is triggered by the top cylinder sensor TWF (B3), and ended by
sensors TWF and TLF (B36) or TWF2 (B31). If only one B3 is installed,
recharging takes place automatically.
Recharging: The stratification cylinder is recharged i.e. only the area up
to the cylinder sensor TWF (B3) is heated. The heat demand is triggered
and ended by the top cylinder sensor TWF (B3).
Charging time limitation (5030)
During the DHW charging, the room heater - depending on the selected
charging priority (prog.no. 1630) and the hydraulic switch – has too little or
no power. It is therefore often practical to restrict the time of DHW charg
ing.
Discharging protection (5040)
This function ensures that the DHW circulation pump (Q3) only switches
on when the temperature in the heat source is high enough.
Application with sensor
The charging pump is only switched on when the heat source temper
ature is above the DHW temperature plus half of the heating excess. If
