the isolator at the boiler for gas?
I haven't touched it... Unless it is an automatic thing?

Solid.... No errors.
im just concentrating on the orange and Cyl wires at the moment! Maybe loose connection.
Has this new boiler been properly commissioned by a gas safe registered plumber?
Why would there be loose connections in a newly connected installation?
Get your voltage tester and check to see what voltage you have at the Lr terminal when the control system is in such a state that there should be a demand.
On the programmer you should have number 1 connected to grey on valve and satisfied on cylinder thermostat, number 3 to cylinder thermostat common and number 4 to room thermostat common.
Did it work correctly before you made these changes?
Are you an electrician? Is this a job for a paying customer?
1 - very intermittently, timer wasn't working. Thermostat was from the 60's.
2 - no, not a qualified one.
3 - possibly, but I was seeking advice from Productive members... Not a game of 21 questions.

Wind yer neck in bonny lad..
When you go to your GP with some ailment or other, do you just sit in the chair and expect him/her to diagnose the problem without asking or you replying to questions??
(s)he is not telepathic and neither are we!!
1, Ok, did you test the whole system through before making any changes to confirm that diagnosis? Are you sure that all of the other parts of the system that you haven't changed are functioning correctly?
2, for the sake of not starting the usual riot I'm going to stay quiet on that one.
3, Who's playing a game? If you want advice then you need to provide all of the information, if you don't then people will ask for the information. If the system was originally fitted as early as the 60's then there is every possibility it started life as a gravity system which has been adapted into a fully pumped system and may not be following the standard y plan.
I have already advised you as to how to test the system to find the fault, you go through each point in the control system testing that it becomes either live or dead as expected when each control is operated.
It can't be a gravity system now if it's got a 3port mid position valve and a Worcester Ri boiler, at least not without something very unusual going on!
Don't get me started on Randall programmers, I can rant about them for hours!
You say you won't touch mains electrics, but here you are working on and asking about mains electrics?
I would suggest you are at a point where calling an electrician in to fix the system is probably the most sensible option. But try to make sure you get one who actually understands heating controls, there are many who pretend to be electricians but don't.
That's the issue everything is set up like a Y Plan, but I have a tank in the loft which feeds the system. Any ideas? Or call in the 'experts'?
Call the experts. A tank in the loft does not mean it's a gravity heating system, the HW and CH are more than likely pumped.That's the issue everything is set up like a Y Plan, but I have a tank in the loft which feeds the system. Any ideas? Or call in the 'experts'?
