Boiler pump does not start when thermostat is turned up
Hello, when I turn up my thermostat the hot water boiler circulating pump does not start. I can manually turn on the pump when a switch is turned on, but the thermostat will not actuate the pump. I have two zones thereby two thermostats, neither thermostat will actuate the circulating pump. The fuse panel is all turned on so I am at a loss. Could it be a transformer or something?
Please help me with advice on what to check for.
Much appreciated, Kirk Bentley
