This function helps to contain the spread of Legionella in DHW stores by systematically activating
the backup heating.
One sensor and one output or demand respectively can be selected for this function.
For thermal disinfection, the temperature at the allocated sensor has to be monitored. Protec-
tion is ensured when, during the monitoring period, the disinfection temperature is continuously
exceeded for the entire disinfection period.
The monitoring period starts as soon as the temperature at the allocated sensor falls below
the disinfection temperature. If the monitoring period ends, the demand activates the backup
heating. The disinfection period starts when the temperature at the allocated sensor exceeds
the disinfection temperature.
Thermal disinfection can only be completed when the disinfection temperature is exceeded for
the duration of the disinfection period without any interruption.
The parameter Cancellation is used for adjusting the period after which the backup heating is
cancelled. If the backup heating is cancelled, an error message is displayed. Thermal disinfection
is cancelled.
