Forced charging
Normally, DHW storage tank charging is started only if the storage tank tem-
perature drops below the switch-on point (DHW storage tank setpoint minus
switching differential). Forced charging can enforce storage tank charging,
even if this switch-on criterion has not been reached.
Starting
If forced charging is activated and the storage tank temperature lies at least
1 K below the normal setpoint, forced charging is started.
Ending
Forced charging is ended when the normal setpoint is reached.
You can decide when forced charging is performed:
Main menu > DHW > Settings > Forced charging:
Never Forced charging protection is deactivated. (However,
manual triggering of forced charging is still possible via
the
DHW button). (Factory setting).
To Normal on
1. change
Forced charging is performed when, for the first time in
a 24-hour period, the reduced setpoint changes to the
normal setpoint. As a result, the DHW storage tank is
completely charged at the beginning of the day
To Normal set-
point with every
change
Forced charging is performed every time the reduced
setpoint changes to the normal setpoint
One-time manual forced charging of the DHW storage tank can also be
triggered by a long push on the central apartment unit’s
DHW button.
During manual forced charging, the DHW symbol on the display blinks.
Setpoint boost DHW charging
To allow for DHW charging, the flow temperature must be higher than the re-
quired DHW setpoint. Set the required setpoint boost here (0..50 K).
Main menu > DHW > Settings > Setp incr DHW charg:
Factory setting 10 K
