Question about Honeywell Programmable Thermostat Heater
I really need your help.
I have 2 Tower motorized valve; fully pumped boiler and when calling for hot water only, the valve does not open at all; I know the valve is not faulty as I have replaced it once. The Central Heating side is perfect.
I have connected the Towerchron QE2 to a Honeywell Sundial Plan Wiring Centre Part number 42005748-001.
Without going into too much details, I connected as follow
Towerchron QE2 Honeywell Programmer Block
Live Brown L
Neutral Blue N
Earth Gre/Yel E
CH On(T4) Gray CH On (Next to E)
HW On(T3) Black HW On
I hope you are able to help.
Many Thanks and Regards
