Charging time max

To prevent that – due to DHW priority – the heating circuit is restricted
or even locked for longer periods of time, “DHW charging with absolute
priority“ can be limited for a certain period of time (5..250 min).

With setting “---“, DHW charging takes place with no limitation
of the charging time.

Main menu > DHW > Settings > Charging time max:

Factory setting

60 min

Your setting

Forced charging

Normally, DHW storage tank charging is started only if the storage
tank temperature 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:

Never

Forced charging is deactivated (however, manual
triggering of forced charging is still possible via
the

DHW

button)

With the first
change to the
normal setpoint

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

With every
change to the
normal setpoint

Forced charging is performed every time the
reduced setpoint changes to the normal setpoint

Main menu > DHW > Settings > Forced charging:

Factory setting

Never

Your setting

Never

First change

Every change

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.
