The led scale (from 1 to 10) represents the intensity of the air ionisation: the more LEDs are
on, the higher is the air ionisation.
1. 1st led (RED LED): power on
2. 10th led (LIGHT BLUE LED): maximum air ionisation
3. Relay will change status approx. at the 3rd led.
NOTE:
Attention shall be taken when the ionisation module is installed near one High Tension
transformer (keep them separated, in particular the output wires)
