The Drayton Wiser Room Thermostat in Anthracite (WN704R0S0901) is a wireless, battery-powered smart thermostat that adds accurate room-by-room temperature control to any Wiser multi-zone heating system. It acts as the master control for rooms fitted with Wiser Radiator Thermostats, and is also the required room controller when using the Wiser Underfloor Heating Controller or Wiser Heat Switch.
Communicating over Zigbee 2.4 GHz with the Wiser Hub, the thermostat can be wall-mounted using the supplied bracket or left freestanding on the included desk stand, giving complete flexibility over positioning. Its matt anthracite finish is designed to complement darker interior schemes and anthracite-finished heating hardware. Manufacturer part reference: WN704R0S0901 (also listed as WN704R0S0901SX).
