Will try my best to explain.
Had a new tank fitted and a 2 port valve put on with new thermostat so i could wire c plan for Honeywell controller.
This evening hot water ran out but boiler not come on.
So i tested with martindale on boiler plug and turned thermostat low and high, power was subsequently supplied to boiler as i raised stat and removed power as i lowered stat. So that part seemed to work. I could also hear 2 port valve opening/closing. I noticed though that rads were also getting warm which should be off. So i turned heating on via honeywell and you could hear the pump operate and water circulate ( which you could not with just hot water on ( even though rads getting warm)
On the tank plumber has put 2 port valve 28mm V4043H1106 on bottom pipe (return) is this correct location or should it be on top pipe? Getting confused, double checked all wiring and that seems fine.
Wired as C plan here with exact same part numbers http://www.free-instruction-manuals.com/pdf/pa_458128.pdf which shows V4043H on top pipe?
Could it be the fact it is a Stainless Steel Vented Cylinder and not compatible with thermostat?
