Hi all.
Conventional indirect system. No HW, CH OK. Three port motorised valve. I suspect the valve needs replacing, but, before i touch anything, i would like to check the wiring connections first, since my room stat is playing funny as well, in the sense that when i manually turn the wall stat to zero, the CH does not switch off. Can you please tell me what you check and how you check the wiring connections with a multimeter? And also, at the first sight, i can you tell if a three port valve is mid-position or just diverter??
Thank you.
