For that one it can be set to L or I. Many thanks for your help, I'll get a new one asap.

OK done that, now everything seems to be as it should, heating going on and off on the room stat, HW on and off on the cyl stat and the valve moving to the correct postions at the correct time. so i guess that means everything is wired correctly and everything is working OK without the...

I really appreciate the help you are giving me here. Done that and the hot water now runs, and the pump/boiler goes on and off as i turn the cyl stat up and down. Also the 3 port valve has switch to HW only.

no that was a stupid question, that cant happen as the progrmmer is removed. :oops:

OK think i understand but won't that mean that both HW off and HW on are live?

Removed the stat and checked it seems to be OK, yes I do have a multimeter. As is said in my last post to jackthom, it seems to me, however im no expert, that the root cause is that HW off from the programmer is permantly live.

No, it doesn't seem to matter what combination of HW & CH i have set it's always live HW off is a yellow wire on the terminal strip and HW on red. I have taken the programmer off of it's base plate and according to the drawing on the back of it the cables are correctly connected, ie Yellow...

Hi, thanks for this. I have disconnected HW Off from the terminal strip and then set HW on from the programmer, which is an iflo with seperate controls for hw and ch, the HW off wire is still live, and HW on is dead, so i guess this means there is a problem with the progrmmer?, the green...

yes, this looks ok, just looking at the wiring diagram supplied with the valve it looks like for some reason HW Off from the programmer is permanently live, this is connected to the grey wire on the vlave and too satisfied on the cyl stat. So perhaps even through the HW on lamp is coming on...

Finally got around to replacing the valve, fitted a drayton mid postion valve, MA1/679-3 All went ok the CH now works fine but i can't the HW to work. Replced all the wires colour for colour old to new, but when i switch the programme on for HW nothing happens, checked the cyl stat that...

i would do but it looks like the system needs to be drained to replace it, i can't see anyway of getting the valve off without removing the complete thing, i don't mind messing about with electrics not so confident when it comes to drain and filling systems. The valve is a very old looking...

OK thanks for the reply, is there anyway of making the system work, short of replacing the valve?

The 3 port valve on my heating/hot water system has burnt out, the main boiler CB trips out. If i disconnect all the electrical connections to the valve will the system be useable by manually switching the valve? TIA Bob

Finally got around to doing this and it fixed it. Thanks for your help. Bob

How easy is it to short the fuse? Do I have to dismantle the motor? Thanks for your help.

Many thanks for this, just checked and same as you open circuit between pins 4 & 5. Others are OK. Know where to get a cheap replacement motor?

Yes the belt is fine.

Hi, looking for some help with the above problem. I have replaced the motor brushes, which were worn right down, I was careful to put the new ones in the same way round as the old ones came out, but I still have the same problem. All help gratefully received. Thanks Bob

Thank you , will do. Bob

Sorry but I don't understand
