My system had an ancient Honeywell v4044 dirverter valve with 3/4" BSP female fittings that was sticking, so I have replaced during this warmer period with a 22mm v4073 mid position valve with the plan of moving to the Y plan. (The cost of pipework and v4073 was cheaper than replacing the v4044)
My question is, until I change to the Y plan, can the Mid position valve be wired to W plan so I have
a) No current the system is in hotwater only
b) Apply current, valve moves to CH only.
Valve wiring configuration on the 4073 is:
White = Heating on
Blue = Neutral
Grey = Hot water off
Green/Yellow = Earth
Orange = Boiler and pump live
So after connecting earth and neutral, do I just connect the white wire to where the brown wire was on the 4044 and leave the orange and grey connected to nothing(but insulated)?
Thanks Simon
