How does the anti-legionella function work?
It works automatically even if the domestic hot water tank is disabled. If the domestic hot water tank is disabled during the disinfection, the system gives an error (error code AH).
When the domestic hot water tank is deactivated in Holiday Mode, the sanitisation program continues to work.
The factory default schedules the anti-legionella function once a week. This can be changed by the installer during start-up.
The customer can also select the anti-legionella function at any time (e.g., for a domestic hot water tank in a holiday home where the electricity has been turned off for a long time).
