SSR303 is a three-ampere Z-Wave relay switch designed to fit on an industry standard 6-pin wall plate, and is an ideal replacement for traditional wired heating controls.  It is a single-channel switching unit that is well matched for use with combi boilers.

SSR303 is easy to integrate with other devices using the interoperable Z-Wave standard, and is suitable for applications that require low-power remote switching. It has three LEDs that give a clear indication of the switch and network status. Buttons on the front fascia provide local control, with tactile feedback.
