DHW heating and space heating take place at the same time.
In the case of tightly sized heat generators and mixing heating circuits, it can occur that
the DHW setpoint will not be reached if space heating calls for considerable amounts of
heat.
Mixing heating circuit shifting, pump heating circuit 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 also be
restricted.

· Periodically
The legionella function is repeated according to the period of time set (operating line
1641). The legionella setpoint is attained via a solar plant, independent of the period of
time set, the period of time will be newly started.
· Fixed weekday
The legionella function can be activated on a fixed weekday (operating line 1642).
When using this setting, heating up to the legionella setpoint takes place on the
selected weekday, independent of previous storage tank temperatures.
During the time the legionella function is carried out, the DHW circulating pump can be
activated.
During the time the legionella function is carried out, there is a risk of scalding when
opening the taps.

When the function is activated, the circulating pump is switched on for 10 minutes
within the release time and then switched off again for 20 minutes.
If a sensor is installed in the DHW distribution pipe, the controller will monitor its actual
value during the time the legionella function is performed. The adjusted setpoint must
be maintained at the sensor during the adjusted "Dwelling time".
