3.6.5 Anti-legionella system
This function is used to prevent bacterial contamination in the hot
water storage tank. If the anti-legionella system function is acti
-
vated, thermal disinfection is carried out. To do this, the con-
nected hot water storage tank is heated up 1x day or 1x week to
a disinfection temperature. The anti-legionella system function is
active for one hour.
The setting of the parameters for the anti-legionella system is
carried out in the "Configuration" rotary switch setting at the
"DHW Configuration" level.
With the factory settings, the storage tank is recharged at 00:15
am if the hot water temperature is less than 65 °C at this point of
time.
Detailed explanations and possible setting values of this function can be found in
chap.

WARNING!
There is a risk of scalds at hot water tempera-
tures of more than 60 °C. This is possible when
using solar energy if the anti-legionella system
is activated or if the hot water target temper-
ature is set to more than 60 °C.
● Install scald protection in the hot water distri-
bution line (e.g. VTA32).
The heating of the hot water for disinfection is carried
out independently of the target temperatures for hot
water set by the user or by the heating expert.

during thermal disinfection.
