The Heatmiser UH4 can be used in conjunction with our mains thermostats. The UH4 is also ideally suited for underfloor heating. When used for under-floor heating an option is available to use zone 4 for conventional radiator control. The UH4 can be used to control any actuator or valve which requires a 230v AC signal. At the same time the UH4 offers the ability to operate a boiler or other heat source through a volt free output.
