Calling all VR71 owners!
What voltage is present at the external demand input S6/S7/S8 terminals on the VR71?
I'd like to add a 3rd party UFH system which uses these terminals to call for heat, so want to make sure that by connecting a UFH wiring centre which has a volt-free output, that this will trigger the call for heat at the boiler.
Thanks in advance for your informed replies
