Patented "zero hysteresis" ensures reliable switching without wasting energy; patent pending for the "light feedback compensation" principle avoids the effect of the lamps repeatedly “hunting” between On and Off, due to poor installation, again preventing a waste of energy
4 position selector: light off (useful for vacations); light on (useful for installation); standard 1 to 80 lux threshold; high 30 to 1,000 lux threshold
For the first three working cycles the delay time (On and Off) is reduced to zero in order to aid installation
