One zone failing to heat rads: controller or valve?
One zone failing to heat rads: controller or valve?
Zone 1 rads working, zone 2 doesn’t switch pump on so rads don’t operate.
Trying to work out whether it’s the motorised valve, or wall controller.
When you remove the electrical box from zone 2 valve , the metal valve operates left and right freely, and when zone 1 is pumping heat , you can use that to open zone 2 which then heats rads.
However when zone 1 controller is off, zone 2 controller won’t turn pump on.
Any suggestions how to test? Should I be able to see zone 2 motorised...
