The Irrad. switch function can be used for operating a relay depending on the
measured irradiation value.
The allocated relay is switched on if the adjusted irradiation value remains exceed-
ed for the adjusted duration. If the irradiation falls below the adjusted value for the
adjusted duration, the relay is switched off.
If the Inverted option is activated, the relay operates vice versa.
