Heatslave 20/25 no power to room stat

[ianmcd]

I checked where the room stat connects to the PCB and I am getting nothing.
I checked between 2&6 and 3&6.

You need to check where the outputs from the programmer are connected to the PCB. If you have no power there, you will have nothing to the room stat.

I can't get my multimeter into the block because the space is too tight, I will need to take the panel off again.. but, see below..

I put that link back in when I removed the room stat wiring and nothing was working.

As above, the space is too tight for the length of my multimeter pins so will check when I get chance to take the panel off ... but...

I have come home from work tonight and all the rads are red hot, the boiler is kicking in and seems to be working.

I will see how things go over the next few days, and on the weekend I will check all the above regardless.
I will then try wiring in the room stat and see what happens. I have also got another room stat ordered so if the old one doesn't work, I will try the new one... or send it back if the old one does work.

Thank you for all your replies and help, I will update when I get chance.
