Resideo VC4011ZZ11 Actuator Molex 2 Position 120V

The Resideo VC4011ZZ11 is a two-position actuator designed for use in hydronic HVAC systems, specifically with zone valves or dampers controlling hot water flow. Made of plastic, it can withstand temperatures between 32°F and 150°F (corrected from 95°F). This electromechanical device operates on standard 120V AC power (60Hz) and features a Molex plug for easy connection. When the VC4011ZZ11 receives a signal from a thermostat or zone control panel, it activates an internal motor. This motor drives a mechanism that opens or closes a valve or damper connected to the actuator. For instance, a heating signal would trigger the actuator to open the valve, allowing hot water to flow through a designated zone. Conversely, when no power is supplied, the actuator returns to its closed position, stopping the hot water flow. The 120V AC operation ensures compatibility with most hydronic system controls.
