This function helps to contain the spread of Legionella in hot water and circulation pipes in the
secondary circuit of the heat exchanger. The Disinfection function starts automatically, if the
adjusted Time at the adjusted day is reached.
The function can also be started manually via the menu item Start?.
If the disinfection starts, the circulation pump switches on.
The circulation pump remains active for the adjustable Runtime.
During disinfection, the speed of the primary pump is controlled so that the adjustable Set tem-
perature is maintained at the hot water sensor. The progress of the disinfection is indicated in
% in the status menu.
The disinfection is considered successfully completed, if during the adjusted Runtime the
temperature at the return sensor has continuously exceeded the value Set temperature-
Hysteresis for the entire adjusted Duration. The date of the last disinfection is indicated in
the status menu.
After disinfection has ended, the circulation pump remains switched on for the adjusted Over-
run time. When the disinfection function is active, it can be cancelled by means of the menu
item Cancel? at any time.
