Daily time switch fucntion - programmable to inhibit main output (for energy saving) Auxiliary output directly driven by the photosensor (light dependent) with use of the optional 19.91 power module available - this permits a flexible lighting system controlled by the ambient light, both with and without the influence of the time switch function 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 Internal battery for set-up / programming without supply and for time / program back-up in case of power failure
