I changed my RMT 230 stat to an electronic type as the readings were way out, the house was at 20 deg and the stat was clicking on and off at 14deg.
Any way I wired it up wrong and blew the TS715 controller. Trip went as well. Think I connected Live and Neutral. The controller was still functioning but didnt actually do anything. Check the stat wiring and have lost the 240v.
Managed to get my boiler working by bypassing the controller with a control link. Glow worm man showed me how.
Just bought a new controller, fitted it and put the old stat back on. Removed control link.
Every thing works fine.
Replaced the stat with the new one, wired up right this time ( I think ), worked fine. Took it back off to mount on the wall, mounted on wall fired up the boiler and now no heating, checked the connections all seem ok. The boiler is showing state S30 - no 240 v controls in the error list. I have also checked the new stat is clicking on and off and making a connection across the terminals using my DVM.
I wired my new stat with the Grey and Black and tucked the Brown away.
So im totally flummoxed now.
There are 3 wires to my old stat
Brown to pin 4
Grey to pin 1
Black to pin 3
Heres a piccy

Put the old stat back on. I now have 240v on the Brown but nothing else.
This is turning out to be an expensive job.
