Yes. Putting a Wiser Radiator Thermostat on every radiator will give you full room-by-room control and zoning. Remembering that you can have a maximum of 32 devices in your system, plus 10 Wiser Plugs.
Important: A lot of heating systems require the radiator in the same room as your main thermostat to have a manual control on it. This radiator should always be left on as your boiler could be damaged if it runs without load. This manual control should not be replaced with a Wiser Radiator Thermostat without consulting a plumber first, as you may require a bypass kit to be fitted also.
