If there is an existing domestic hot water cylinder, the Active set-
ting must be selected.
Factory setting: Active
Target value for the flow temperature during cylinder charging

Define the days on which you want the anti-legionella function to
run. On these days, the water temperature is increased to above
60 °C. The circulation pump is activated. The function ends after
120 minutes at the latest.
If the Absence function is activated, the anti-legionella function is
not carried out. As soon as the Absence function ends, the anti-
legionella function is carried out.
Heating installations with heat pumps use the back-up boiler for
legionella protection.
Factory setting: Off
Define the time at which you want the anti-legionella function to
run.
Factory setting: 04:00
The cylinder charging starts as soon as cylinder temperature <
desired temperature - hysteresis value.
Factory setting:
–
5 K for a conventional heat generator
–
7 K for a heat pump
Desired temperature + offset = flow temperature for the domestic
hot water cylinder.
Factory setting:
–
25 K for a conventional heat generator
–
10 K for a heat pump
Setting the maximum time at which the domestic hot water cylin-
der can be charged without interruption. If the maximum time or
the target temperature is reached, the system control enables the
heating function. The Off setting means that the cylinder charging
time is not restricted.
Factory setting:
–
60 mins for a conventional heat generator
–
90 mins for a heat pump
Setting the time period during which the cylinder charging is
blocked after the maximum cylinder charging time has elapsed.
During the blocked time, the system control enables the heating
function.
Factory setting: 60 min
When charging the domestic hot water cylinder, the mixing cir-
cuit is heated in parallel. The non-mixed heating circuit is always
switched off during cylinder charging.
Factory setting: No
