Legionella funct duration

(1646)

With this function, the time will be set, during which the legionella function set-

point is activated to kill germs.

If the colder storage temperature rises above the legionella function setpoint by -1

K, the legionella function setpoint is assumed as met and the timer starts running.

If the storage temperature drops by more than the switching difference +2 K be-

low the required legionella function setpoint, the duration has to be met again. If

no duration has been set, the legionella function has been met immediately on

reaching the legionella function setpoint.
