Yes. But I could just fit a switch to the power head cable too. Right?
The objective is to switch the radiators off an just have the hot water. ie: boiler on.

Well Ray you've had alot of good advice from the members on here and unfortunately some not so nice criticism, all I will say is always use a fully qualified electrician for the wiring, you are your own man and will do as you please but we only want you your family and friend to be safe.

It is not unusual to fit a 5 way plug to a existing power head cable it saves messing around in the heating junction box which contains many wires that can be very awkward to distinguish what does what it's also safer, a loose cable connection or wrong cable position can cause alot of problems please keep safe .

Thanks for that.

As you can see from my previous comments the job has been passed to a registered electrician who has agreed with the proposed works to be carried out. The cost is going to be about £200 excluding new equipment and will be completed in the summer or late spring.

It just occurred to me after the fact that the main objective of this work is to enable the lady who owns the property
to be able to turn the CH off in the summer and just have the HW on which she ought to be able to do by default but can't
because it has not been set up the way you would normally set up an S-Plan installation. It is functioning as it is but this
inability to select HW only has had an impact on her fuel consumption last summer burning far more oil than she needed
to have done. This work is to remedy that moving forward.

But that objective could be met by simply inserting a switch in the CH zone valve cable to cut the power off when CH
is not required in the summer months and, of course to restore the power at the end of summer when required. That could be done without touching the current control installation. The bypass valve is working ok. I know that because I have checked it.

So I can't think of any reason why this can't be done.

The CH zone valve is the silver one in the picture.

The wiring center is on the right in the other picture. The CH cable is the black one right of center.

I am talking about a surface mounted DP neon switch underneath the wiring center.

Does that sound feasible?


Thanks

Well yes of course its possible but
you can achieve the same result by selecting off on programmer or simply turning down room stat!

There is no "OFF" on the programmer for the CH. It's either all or nothing.
I wouldn't expect anyone to go through the entire thread but if you look at my origin posting #1 you'll get the gist.

You're wasting your time.
