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.

Note
• Switching sequence: 50 % – 75 % – 90 % – 100 % –
Off.
• UVC lamps on: LED is lit blue:
• UVC lamps off: LED is lit green (energy-saving
phase in Eco mode).
• Select Eco mode 50 % if the water is only slightly
soiled.
• Select Eco mode 75 % or 90 % if the water is more
soiled.
• Select operating mode 100 % if the water is very
soiled.
How to proceed if the water is green:
• Start with operating mode 100 %. As soon as the
desired result is achieved, change to Eco mode
50 %. If the water becomes green again, choose
the next higher Eco mode until you achieve the
desired result permanently.
How to proceed if the water is clear:
• Start with Eco mode 50 %. If the water starts to go
green, select the next higher Eco mode until you
achieve the desired result permanently.
