I've put the cover back on now Ian, but it is as per the BASIC SYSTEM 1 you posted yesterday and as i have described above. I think I am going to go with what Stem posted and set it up as a mini programmer.

They can't have been in 4 & 6 Ian, as I say, I just disconnected and assumed that's where they were based on the re-wiring instructions that came with the ST9400C. :confused:

Thanks fellas, as I said before, a proper schoolboy error in not taking a photo of the ST699 before disconnecting!! However, I have re-instated it so we got our heating back. I've confused issues a lot here by assuming the cable from the boiler was for the CH and the cable from the Pump was...

Thanks for all your help on this Ian, appreciate it. Take on board what you say about leaving 1 & 2 free, but what do I do with the 2 spare wires?

Looking at your link, it would appear the ST699 was wired for a Basic System 1 as I don't have thermostats.

I don't know Ian. I'm all confused about what I have and haven't done now! As I say, I looked at the replacement wiring diagram and it all looked straight forward, so I removed the cables and put them into the terminals indicated.

Hi Ian, As I've just said in the previous reply, I don't know what system I have! Yes, everything worked as expected and has done for over 20 years. I do have hot water tank in airing cupboard and I've just been and looked and there's nothing in there apart from pipework and the switch (we...

Hi, I don't know what system I have. We had a GlowWorm Ultimate 50BF boiler installed around 24years ago and they installed the ST699 at the same time. The boiler is still going strong (I know its not that efficient, but I'm loathed to swap it out for the sake of it) We do not have any room...

Hi Ian, I'll tidy the wires. Yes N & L were previously in N & L on the ST699. Regarding the locations of the other cables, I'm pretty certain that I did the following swap, although, I'm second guessing myself now: using your list: N - Blue-A came from N L - Brown-B came from L 1 - Brown-C...

Hi Ian, I don't have any pics of the ST699 wiring - schoolboy error, I should have taken some prior to disconnecting, but I thought it was a straightforward swap so didn't bother. No, I meant "have" cables linking on the ST699 as they are still connected. So I disconnected the power supply...

Afternoon all, I'm hoping someone can help here as we are now without heating! Bit of background - I had a ST699 programmer controlling our heating and hot water. It has worked flawlessly for 20 odd years, but last year, it started playing up. First thing that happened was that we couldn't...
