With the Philio Double Relay Insert, you can integrate existing electrical installations (e.g. lighting, airing systems) into a Z-Wave network. Thus, the connected devices can still be controlled with the existing wall switch, butthanks to Z-Wavealso via remote control, smartphone or sensor-controlled automation. Thanks to its calibration technology the Philio relay module cannot only be used to switch AC devices ON and OFF, it also works perfectly with many kind of light, e.g. incandescent, fluorescent and LEDs. In addition to this, the module can also switch 12V/DC devices like 12V MR-16 lights. The compact radio module is placed in a wall box right behind the normal switch. The switch is no longer directly connected to the loads but acts as input device for the Philio insert that is controlling the loads. The switch only sends control signal to the insert which controls the loads then again. The solution works with all switch design. You can use a momentary or a toggle swit
