Any advice appreciated
When changing a room stat on a y plan
I put power on to trace live wire and found with timeclock C/H off and H/w on, the load side was also live.
Is that normal
I have looked at wiring diagrams but not sure, could it just be possibly going through the valve contacts etc, and somehow returning via the white wire
Aside from the sundial /honeywell, site info, does anyone know of any info regarding the grey and orange, internal switch wires and positions,in relation to the actual valve positions
Not sure either the function of the grey to the cyl stat and in what state the stat gives an output (ie Tank hot or cold), in the diagram it also looks like the grey becomes live when the H/W timer is off.
Thanks
