2port zone valve wiring connections?

[Mister Banks]

So on a 5 wire zone valve the NO is orange but on a 6 wire zone valve the NO is grey. Weird that Honeywell use different colours.

The grey wire is the permanent live. That wire goes to the NO on the zone valve in all the diagrams inc. the Honeywell ones. It doesn't matter whether it is 5 wires or 6 wires. The only difference with the 6 wire is that there is an extra wire (white) going to the NC on the zone valve.

The orange wire is always the switched live.

I don't know which diagram you are saying is different? They all look the same to me.

On your photo it actually says Grey (N/O) and White (N/C).

Take another look, they are different. Look at the micro switch part of the zone valve.

Which diagrams are you looking at? The diagram which you said before was different, is the same as all the others. The grey is going to the NO. The orange is the switched live. Which diagram shows it the other way round?

The diagram below it is also from Honeywell. It shows the same thing but in a slightly different way.

The diagram you attached above shows the grey on the COM not the NO. The diagram you provided earlier in post #8 shows the grey on the NO and the orange on the COM.

Does it make a difference how they draw the diagram? The one you posted looks really old fashioned. Maybe convention has changed. The important thing is that the grey is the permanent live, the orange is the switched live, on both.

Below is the latest drawing from Honeywell for 5 wire S plan

I know the result is the same in my situation but the diagrams are different as is the diagram printed on the actual valve. The diagram i posted is from the Honeywell Heating Controls Wiring Guide Issue 17, I think the latest guide is issue 19 so not that old.

On the valve itself it actually says Grey (N/O)!!

Yes it does but on the diagram I posted from the wiring guide is shows orange on the NO.

This is the latest 6 wire diagram from the Honeywell website.

Which is different to the 5 wire zone valve wiring diagram.

 

[MNW67]

Which is different to the 5 wire zone valve wiring diagram.

This is getting ridiculous. Below are the latest diagrams from the Honeywell website, shown together, for 5 and 6 wire valves. Apart from the extra white wire on the second diagram, the drawing of the switching is identical.

I don't even know what you are trying to demonstrate. Your OP said that on your diagram (third one down) permanent live was orange and the grey wire was the switched live to the boiler. But that is clearly not the case. The grey wire is taking the permanent live from terminal 1 to the valve, and the orange wire is taking the switched live to terminal 10 and then to the boiler.

You're not looking close enough, forget about the naming of the switch positions, look at the diagram of the switch. The switch is drawn the opposite way around between the 5 wire and 6 wire wiring diagrams resulting in the wiring colours being different.

I think you're the one who's been hung up on the names!

How is this:

Different from this? (apart from the extra wire)

Let's agree to disagree.
