I wonder if you could assist me with a problem I am having with a replacement part I bought? The part in question is a 3 Position Diverter Valve from Honeywell.
I have just got round to using this and went to fit it and noticed that this part has 6 wires whereas the original part had 5 wires. The question relates, I think, around the brown wire. The original part is a Honeywell 40003916-003 (Alternate Number is V4073A1039-6). This has 5 wires - Orange, Grey, White, Blue and Green/Yellow. The part I have is a Honeywell 40003916-001 which has 6 wires - Orange, Grey, White, Blue, Green/yellow and a Brown wire. I am not sure where to connect the brown wire. Any help of this matter would be gratefully appreciated. Barry
how can I change my diverter valve, do I have to drain the sysyetm?

The problem is that you have a power head for a 2 port valve ( part suffix 001) whereas you need the power head for a 3 port mid position valve which has the suffix 003. I dont think you will be able to use the head you have purchased as a replacement.

Think you have the wrong replacement, the six wire head is used on zone valve
