When this setting is used, DHW heating
is continuously released as long as it is
switched on. The DHW setpoint is
always the nominal setpoint, unless the
legionella function has been activated.
Time programs HCs
When this setting is used, DHW heating
is released during the occupancy times
of the connected heating circuits. If at
least one of the heating circuits is at the
Comfort level, DHW heating will also be
released. If all heating circuits are at
the reduced level or in protective mode,
the DHW level will also be set to
reduced.

When using this setting, a specific time
program is available for DHW heating.
For every weekday, a time program
with a maximum of three on phases
can be set. During the release time, the
nominal DHW setpoint applies, outside
the release time, the reduced DHW
setpoint.
