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.
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.
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.
Legionella function (1640)
Function to kill legionella germs by heating up to the set legionella function
setpoint (see programme number 1645).
Off: Legionella function is switched off.
Periodically: Legionella function is repeated periodically, depending on
the set value (prog. no. 1641).
Fixed weekday: Legionella function will be activated on a certain
weekday (prog. no. 1642).
Legionella funct periodically (1641)
Setting the interval for the legionella function periodically (recommended
setting in case of additional drinking water heating by solar plant in
connection with a storage tank mixing pump).
Legionella funct weekday (1642)
Selection of the weekday for the legionella function.
Legionella funct time (1644)
Setting the start time for the legionella function. With setting --- the
legionella 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
setpoint is activated to kill germs.
