Time setting central heating: The DHW temperature will be switched
over between the nominal DHW temperature value and the reduced
nominal DHW temperature value depending on the time switching pro­
grams. Every time, the switching-on time is moved forward.
It is moved forward by 1 hour.

Time hot water: The DHW temperature is changed over between the
DHW temperature setpoint and the reduced DHW temperature setpoint
independently of time switching programs of the heating circuit. For this,
time switching program 4 is used.

Charging priority (1630)
This function ensures that the boiler capacity is primarily made available
for DHW in case of simultaneous capacity demand by room heating and
DHW.
Absolute: Mixer and pumped heating circuits are blocked until the DHW
has been heated up.
Shifting: Should the boiler capacity not be sufficient to heat up DHW,
mixer and pumped heating circuits will be restricted.
None: Charging DHW is carried out in parallel with heating operation.
MC shifting, PC absolute: Pumped heating circuits are blocked until the
DHW has been heated up. Should the boiler capacity not be sufficient,
the mixer circuit will also be restricted.

nection with a storage tank mixing pump).
Legionella funct weekday (1642)
Selection of the weekday for the legionella function.
Legionella funct time (1644)

ella function will be carried out the first time DHW heating is enabled.
Legionella funct setpoint (1645)
Selecting the set temperature required for killing the bacteria.
Legionella funct duration (1646)
With this function, the time is set during which the legionella function set­
point is activated to kill germs.
