[QUOTE="SPECIAL LOCATION, post: 256139, member: 250"] Agreed... The final 230v trigger to boiler has two inputs one from the cylinder stat and one from the orange @ valve. 1) Water ON: Heating OFF: is 230v from Programmer - Cylinder Stat to boiler. {valve in home position pulled back by spring} No orange voltage. 2) Water OFF: Heating ON: is 230v from programmer - room stat - White of valve -internal valve switch - out on orange to boiler. {valve driven fully over by 230v on white & grey wires} 3) Water ON: Heating ON: is 230v from Programmer - Cylinder Stat to boiler. {valve is in the mid position stalled by voltage on white wire through internal diode & resistors} 4) Water OFF: Heat OFF: 230v will still be going into the valve from the Grey wire. {No output to boiler, but the position of the valve can be dependent upon its last operate position.} In condition 3) or 4) the orange if open circuit from other wiring can show 60v - 80v via the internal diode & resistors of the valve. :) [/QUOTE]
