Time programs HCs: The DHW temperature will be switched over
between the nominal DHW temperature value and the reduced nominal
DHW temperature value depending on the time programs. Every time,
the switching-on time is moved forward.
It is moved forward by 1 hour.
RA-0000077
Time program 4/DHW: The DHW temperature is changed over between
the DHW temperature setpoint and the reduced DHW temperature
setpoint independently of time programs of the heating circuit. For this,
time program 4 is used.
RA-0000078
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.
