With the WiDom flush-mounted Double Switch Relay, you can integrate existing electrical installations (e.g. lighting, airing systems…) into a Z-Wave network. Thus, you can control two connected devices at the same time and still independent of each other. The connected devices can still be controlled independently with the existing wall switch, but – thanks to Z-Wave – also via remote control, smartphone or sensor-controlled automation. The modul has got two different versions: L version and N version.
The module is equipped with contact protection technology (zero crossing) which reduces the electrical stress on the relay contacts and ensure a longer life.
The compact radio module is placed in a wall box right behind the normal switch. The switch is no longer directly connected to the load but acts as input device for the WiDom insert that is controlling the load. The switch only sends control signal to the insert which controls the load then again. The solution works with all switch design. You can use a momentary or a toggle switch. It’s recommended to use wall boxes with 65mm depth. But smaller boxes with only 45mm depth can be used also if there is enough space behind the switch. The available space depends on the size of the traditional switch, the dimensions of the wall box and the amount of additional cabling placed in this box.
