Legionella start:
The time which was set determines
when the legionella protection function starts.
The legionella protection function is carried out by
the auxiliary heating on the preset day of the week, at
the preset time, if the auxiliary heating has been acti-
vated.
For this function, the controller sets the flow target
temperature to 76 °C/74 °C (2 K hysteresis). The
legionella protection function is terminated when the
current flow temperature at the cylinder has reached
73 °C for at least 30 min, or after 90 minutes if 73 °C
is not reached (e.g. if hot water is drawn during this
period).
The processes of the legionella protection function
start in a connected drinking water station VPM W.

Circulation pump:
The setting range 1 - 100% is not a
setting for the pump output, but is a division of
time periods relating to an interval of 10 min.,
e.g. 80% = 8 min. operation, 2 min. break.
The time period is active. In this time period, the
circulation pump clocks in accordance with the
set percentage value. The circulation pump does
not start if the DHW cylinder is still too cold.

If sufficient solar energy is
available, a connected buffer tank VPS /2 is
heated beyond the target temperatures for
heating and hot water to the maximum tempera-
ture set here.

The heating circuits connected to the
buffer tank must be mixed circuits.
