2. 5. 7 Anti-legionella Function
Activated with the boiler connected to a tank by an NTC
sensor
This function prevents the formation of Legionnaire's
disease bacteria which may develop in the piping
and indirect cylinders at temperatures between 20°C
and 40°C. If activated, whenever the indirect cylinder
temperature stays below 59°C for over 100 hours, the
boiler heats the water in the indirect cylinder until it
reaches 65°C for 30 minutes.
