How is the zone valve on a hot water heater controlled?
Each zone valve is controlled by its own zone thermostat. End switches in each zone valve control the central circulator and the burner. On a call for heat, the valve is opened.
What should I do if my hot water zone is not working?
Observe the control devices; the valve should close. The auxiliary equipment should stop unless the end switches are wired in parallel and another zone is calling for heat. If the auxiliary equipment continues to run when the zone valve satisfies, lower the setpoints below room temperature on all the zones and repeat the procedure.
What causes hot water to run through the heating zone?
This motor can sometimes break or wear down, and the valve will stay closed or open. An open valve will cause hot water to run through the heating zone whenever the furnace turns on.
How to troubleshoot a malfunctioning heating zone?
Locate the thermostat that controls the heat in the zone that is cold. Pull the thermostat off the wall and look to see where the wires lead.

What is the zone valve on a radiator?

What does it mean when a zone valve breaks?
The valves are called zone valves and they are wired directly to your thermostats.
