[QUOTE="kme, post: 26898, member: 113"] Steptoe: The actuators (yep, zone, or 2 port valves) connect to the UFH control system. I believe o/p needs the control system to fire the boiler on demand. Beemer - If memeory serves, the Worcester uses low voltage switching for external controls. It USED to be pins 4 & 5, but if you can post or PM the boiler wiring instructions, we can confirm. I also need to know the spec. on the output signal from the UFH controller - is it throwing 230V at the boiler? If so, you`ll need a relay in line:) [/QUOTE]
