Hi Gents, full disclosure. Electrician not a plumber. Got called to look at a Gabarron CMX15 that was dead, discovered the Safety Limiter device on the CH side had tripped, reset it and bled the radiators are recharged to 1.5bar per the manual. long story short it has tripped a couple of times since. Done it today while I was there after only being powered up for 5 minutes, the water was stone cold and the Sr value was 18 (from the diagnostic routine) , it also this time refused to reset even with the mains power off. In my mind the device itself is faulty. I did call Elnur UK but the bloke didn't seem to have a clue and wanted me to send him all the details in an email, never got any reply. Am I missing any other reasons for that switch to keep tripping
