I am in need of a new boiler this spring (combustion chamber collapsing in on itself) so I dont want to pay for a service call My downstairs zone doesnt seem to be responding to the thermostat control Is there an easy way to tell whether it is 1) thermostat, 2) wiring to zone valve or 3) zone valve? |
Yes, a pic of the boiler, valve, and stat would help. |
