Selecting the operating mode
It is possible to choose from four operating modes to match irradiation of algae and germs to
the requirements of the situation.
The duration of irradiation is automatically controlled on the basis of the measured water tem-
perature and the selected operating mode. The ratio of the switch-on time to the switch-off
time of the UVC lamps is dependent upon the operating mode. The higher the percentage value,
the longer the switch-on time in relation to the switch-off time.
In 100% operating mode, the UVC lamps are permanently switched on.
