Our Wired underfloor heating wiring centres have been designed to simplify the wiring process. Using our wiring centres in your application means that the actuator,
boiler and pump connections are wired from a single point. TPX08 is used in conjunction with our cable thermostat TP501/TP528/TP538/TP908/TP818
8 zones can be controlled as well as providing an output for circulation pump and boiler. Up to 5 thermal actuators can be connected to each zone.
