Electric Thermostats

FH-BU



The FH-BU is a six-zone floor heating wiring centre for use in systems utilising wireless room thermostats. In addition to providing a structured wiring system for thermal actuators, the FH-BU also incorporates two voltage free heat demand relays that are activated when one or more zones call for heat. The two relay solution allows for separate control of a floor heating zone pump and a boiler.

With this arrangement, the boiler may by used for normal radiator heating and hot water service provision, without the need for external relays.
