When the function is activated, the circulating pump is switched on for a fixed time
of 10 minutes within the release time and then switched off again for 20 minutes.
If a sensor is installed in the DHW distribution pipe, the controller monitors its
actual value during the period of time the legionella function is performed. The
adjusted setpoint must be maintained at the sensor during the adjusted "Dwelling
time".
