SSR302 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 two-channel switching unit that is well matched for use with systems that require separate channels for heating and hot water.

SSR302 is easy to integrate with other devices using the interoperable Z-Wave standard, and is suitable for applications that require low-power remote switching for two channels. A tri-colour LED gives clear indication of the switch and network status. Switches on the front fascia provide local control, with tactile feedback.

Fully integrated with our own products and running on the interoperable Z-wave standard this is an ideal candidate for applications where 2 channel low power remote switching is required. The tri-colour LED gives clear indication of switch states, while four tactile buttons, concealed behind a flap on the front fascia, provide local control.



  • Boiler and hot water control    

    SSR302 is ideal for boiler control for heating and hot water when used together with a SRT321 room thermostat. Manual on and off buttons on the front panel provide local override functionality.
