Hi all,
I'm looking to rewire my control centre (the installer left it in a mess with wires hanging around everywhere) and figure out why my hot water is not coming on with the programmer.
Setup at the moment is:
Intergas boiler HRE
1 zone valve for hot water tank - 6 wire.
1 zone valve for radiators on 1st floor
1 zone valve UFH manifold - ground floor.
Wiring wise is setup for Hot water priority - the return from Hot water zone valve feeds the circut for the radiators zone valve.
UFH manifold does its own thing, so if hot water is on, and the UFH comes on, it will get the heat.
On the other hand, the UFH only needs low temperature water circulating. The Hot water and upstairs rads require a higher temperature...
What im thinking is can i setup the wiring such that the Hot water + rads are both connected as "DHW" on the boiler - set the temp to 65-70 degrees.
The UFH is then wired as central heating to the boiler, temp set to 40-45 degrees with a blender already on the manifold to any adjustments should the hot water or upstairs rads be on...
What are peoples thoughts on this?
At present hot water is not coming on at all, if i manually open the zone valve, the boiler kicks in for hot water mode and all works, so i suspect an issue with the programmer... 1st floor heating doesn't work unless i cycle through the hotwater settings on the programmer to turn On and then off the hot water! Its a "feature" of horstman programmers, but seem to be the only ones i can find which allow the return from the DHW zone valve to feed as the common for the heating program... most others seem to have a common live...
