We have no plan to control any aspects of the Boiler
This is done with the Valiant time clock and VR65 Control Unit
Thanks
Not going to get to involved with this one richard but VR65 is just a wiring center i can see what you are trying to do and when i put a new system in my home i wonted to zone it and did and have 5 zones, have had this system for years and works very well.
you asked for help and there are a lot of lads and poss girls on here that tried to give you the correct way to do it but you did not seam to take any advise which i dont understand what ever you decide to do will poss work in some way in the end but if you put your method of controls in my home i know i would not be happy with the way it would work , every one knows why and have been trying to tell you.
