24h/day
When this setting is used, DHW heating is continuously released as long as it is On. The DHW setpoint
is always the Nominal setpoint, unless the Legionella function has been activated. Setting Once/day
or Several times/day has no impact. When DHW heating is Off, the Frost Protection setpoint applies.
- 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 operates at the Comfort level, DHW
heating is released also. If all heating circuits operate at the Reduced level or in Protection
mode, the DHW level is set to Reduced also. To ensure that the DHW storage tank is already
charged when space heating is started, the release of DHW heating is brought forward in time against
the switch-on point for space heating (including optimum start control). The extent of forward shift
depends on Charging (5010) (Once/day or Several times/day). When selecting Once/day, the forward
shift for the release of DHW heating is 2.5 hours. When selecting Several times/day, the forward shift
for the release of DHW heating is 1.0 hour. If the Legionella function is pending, it will be performed
when DHW heating is released for the first time in the morning. When DHW heating is Off, the Frost
Protection setpoint applies.

Time program 4/DHW
When using this setting, a specific time program is available for DHW heating. For every weekday, a
time program with a maximum of 3 on phases can be set. During the release time, the Nominal DHW
setpoint applies, outside the release time, the Reduced DHW setpoint. If the Legionella function is
pending, it will be performed when DHW heating is released for the first time in the morning. Setting
Once/day or Several times/day has no impact. When DHW heating is Off, the Frost Protection
setpoint applies.
DHW priority
When both space heating and DHW heating call for heat, the DHW priority function (parameter no.
1630) ensures that while DHW charging is in progress, the boiler’s capacity is used primarily for DHW
heating.
-
Absolute : Mixing and pump heating circuits stay locked until DHW heating is completed.
- Shifting : If the capacity of the heat source is not sufficient, the mixing and pump heating circuits will
be restricted until the DHW is heated up.
-
None
: DHW heating and space heating take place at the same time. In the case of tightly sized
boilers and mixing heating circuits, the DHW setpoint may not be reached if space heating calls for
considerable amounts of heat.
- MC shifting, PC absolute : The pump heating circuits stay locked until the DHW storage tank is
heated up. If the capacity of the heat source is not sufficient, the mixing heating circuits will be
restricted also.
DHW heating can be released in 3 different ways:
