Universal Synchron Motor 6W, 230V AC

DESCRIPTION:

Universal Synchron motors open and close most motorized zone valves in hot water heating systems that incorporate central heating radiators. These valves are actuated by the thermostat in a zone, which admit or limit the flow of hot water to the zone. A typical indication of a defective zone valve motor is failure to respond to the signal from the thermostat. Manually actuating the spring-loaded valve lever will indicate no mechanical defect, and tests with a multimeter will verify that the valve motor is receiving 24-volt power.

Synchron motors in most zone valves are replaceable without draining the water from the system.

Simple steps to replace a synchron motor in a motorised valve actuator:

1. Turn off electrical power.

2. Remove the valve cover.

3. Unscrew the single screw that secures the synchron motor to the valve body.

4. Push the valve's manual actuating lever - located on the end of the valve below the power wire connector - into the "Open" position, and hold it there.

5. Lift the synchron motor unit up and away from the valve body. Release the manual actuating lever, and allow the valve to spring back into the "Closed" position.

6. Cut the two wires leading from the synchron motor to the plastic terminal connector. Leave enough existing wire at the connector to splice the new motor wires.

7. Push the valve's manual actuating lever into the "Open" position, and hold it there. Install the new motor unit into the valve body. Insert the single mounting screw and tighten. Release the manual actuating lever, and allow the valve to spring back into the "Closed" position.

8. Splice the two wires from the motor to the two existing wires, using the supplied screw on connectors.

9. Replace the valve cover and restore power to the system. Test the action of the valve by adjusting the thermostat to call for heat.
