Fitting v4073 into worcester heatslave

[baileyboy40]

Hi everyone, could really do with some help.
We have a 18 year old worcester heatslave 15/19 oil combi
The old v4044 divertor valve packed up. I have fitted a v4073 to this boiler but could do with pointing in the right direction with the wiring, as it is a heatslave it is on a w plan . have searched for diagrames but can't seem to find what i need. everyone says to replace the old v4044 divertor with v4073 mid position valve but with no help as to wiring

Why try and fit a mid position and not just replace like for like with a 4044 diverter?

was advised the v4044 was old and hard to get hold off and that everyone was replacing these valves with the v4073

No mate there's nothing old about it, it's a current valve. The difference is the 4044 is open to either heating or hot water, the 4073 has the additional position of open to be both and has the extra wires accordingly.

but a couple of the wires can be combined to make the mid position a diverter valve which is what is wanted...

can't think which ones though!

All very well -BUT the correct Worcester part comes with a prewired plug to enable it to lug on the The PCB, if you don't use the genuine article you have to "bodge" the wiring with crimps or worse connector strip (YEEHA!)
