Operation
An active legionella protection function (parameter [Anti-Le-
gionella day]) involves heating the connected storage tank to a
disinfection temperature 1 x a day or 1 x a week. The legionella
protection function is active for an hour.
The maximum hot water temperature set by the user or
the heating technician is ignored when hot water is
heated for disinfection purposes.
A connected circulation pump is automatically switched
on during thermal disinfection.
Setting the parameters for legionella protection is carried out in
the rotary switch setting
"Configuration"
in level
"DHW Con-
figuration"
.
Using the factory settings, the storage tank is heated at 03:30
hours if the target hot water temperature is below 65 °C at that
time.
More detailed explanations and possible setting values for this function can be seen
in chapter 5.2.4.
