The UH2 can be used with any of our 230v wired thermostats and allows up to 4 to be connected at once. It has an output for a hot water cylinder plus the system boiler and pump as well as an optional zone for radiator control separate from the underfloor heating.
If your underfloor heating system covers up to four rooms that will be controlled by independent thermostats, the UH2 wiring centre is the one to use. If the system uses five or more thermostats, you’ll need to use the UH3 WIRING CENTRE
