How can I check if the call for central heating is working?
When the control panel is set to CH the mid valve doesn't move there.
I changed the syncro motor but still no joy.
Though if I manually move the mid position valve from HW to mid - it automatically continues through to CH and the CH comes on.
I am wondering if the small Circuit board in the mid position valve is toast - can that be swapped out?
But just want to check that is the case by proving that the call for CH is reaching the mid-valve just not making it move.
Wanted to avoid the wet side!
Cheers
