Help needed. Just brought my new house in the summer. Never needed the heating on until this week but the kitchen is an extension and tiled floor so feeling a bit frosty now.
The house is all GCH but the kitchen is underfloor.
When we moved in there were 3 thermostats. One is the main house radiators. The second is the rt500rf and the 3rd was the remnants of a stat backplate in the kitchen itself. With just a T&E live and neutral terminated but no control mechanism.
I have since replaced it with a Honeywell dial stat terminals 1 and 3. When i turn it up i can hear the contact kick in at the underfloor controls. But theres nothing happening.
Today after some basic disassembly i have found the feed indeed goes to the contact then off to a salus receiver. Realising this was what the 2nd stat was for i have been checking this forum and seen similar problems.
I have now got to the point that the red power light is on the receiver and when i turn the temp up on the stat i get the flame symbols and green light on the receiver. But the boiler doesn't kick in at all. I presume the jumpers are ok as they look a bit random to the untrained eye.
But this extra stat cable that i have on a Honeywell at the moment is also confusing the hell out of me. It seems necessary in its current wiring due to the contact being fed from the switch line and then the salus receiver from there.
Heres a pic if it helps anyone understand
