Hi, i have just moved into a new home. It had a 3 port valve which only seemed to work for central heating when you had hot water. so you always had to have hot water even with the heating. So i decided to buy a new valve and wire it in. Then when i took the head off the 6 way round junction box, the orange and grey wire were not connected to any where. just cut and left.
So i bought one of those 10 way honeywell junction boxes and followed the diagram on there.
I have had lots of different problems with it.
1st i can get hot water, nothing else. Then i can get hot water and central heating. No mid position.
Now i can have hot water and mid position but it wont give me central heating on its own.
The valve moves, stat calls for heat but, the pump doesnt seem to kick in.
Am thinking that its got something to do with the wiring in the programmer. The programmer is a potterton e3002. Its not wired the way it says on the back. It basically has a link from the live to number 5. And then a live to 3and4. Thats it.
Can anyone here give me some advice? The wiring from the programmer goes into 2 other wiring centres in the kitchen before entering the airing cupboard and am lost with using a multimeter.
Also, does anyone know of any good causes you can go on to learn the wiring and fault finding of central heating systems? Or is this a touchy subject as were not allowed to work on them unless part p.
I have signed up for the one day course with Honeywell.
Hopefully this will do me some good.
Thanks guys.
A bit long winded i know
