3 port motorised valve wiring question.

[Dalminty]

Good evening everyone,
Question 1
I have just replaced my 3 port motorised valve head and wired it in.
When looking at my chocolate block connector the orange and grey wires are in different places than the diagram on the instructions shows.
As you look at the terminal block for all the wiring, there are 10 segmants to the chocolate block.
My wiring shows no 8 on the choc block a grey wire and no 7 on the choc bloc a orange wire.
On the instructions,no 8 shows orange and no 7 shows grey.
Could someone please tell me which is correct.

Question 2
Could the above wiring problem affect my heating programmer as I now can't have just hot water without having the heating on aswell.
Before I wired in the new valve I was getting heating on with water aswell.
The programmer seems now to be working the other way round.
The programmer is a Honeywell ST699.

Thanks everyone.

Grey is HW off and orange is to connect to boiler live. Without seeing your wiring centre I couldn’t see what’s what.

What make is the motorised head?

The valve head was bought from toolstation and is boxed up as corgi.The valve assembly is a Banico zvm22.
Thanks for your reply

Banico are kind of a Honeywellreplica.
if memory serves I am pretty sure that their heads are interchangeable. Have had a problem with a few of them failing in a short space of time

Thanks Riley.
I have replaced the head and wired up exactly as the wires came out.
I used to put the heating on at the programmer and always have to put the water on aswell otherwise the boiler would not fire up.
Since changing the valve and wiring it in I have to put the heating on and the water which means that when summer comes the rads will be on.
