Funct. Activation / Deactivation Activated, Deactivated Deactivated
This function helps to contain the spread of Legionella in DHW stores by system-
atically activating the backup heating. One sensor and one relay can be selected
for this function. For thermal disinfection, the temperature at the allocated sensor
has to be monitored. The monitoring period starts as soon as the temperature
at the allocated sensor falls below the disinfection temperature. When the moni-
toring period ends, the allocated reference relay activates the backup heating. The
disinfection period starts, if 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.
Starting time delay
If the starting delay option is activated, a starting time for the thermal disinfection
with starting delay can be adjusted. The activation of the backup heating is then
delayed until that starting time after the monitoring period has ended. If the moni-
toring period ends, for example, at 12:00 o'clock, and the starting time has been set
to 18:00, the reference relay will be energised with a delay of 6 h at 18:00 instead
of 12:00 o'clock.
