Resideo VU842A1046 Actuator
The Resideo VU842A1046 is a professional-grade 24V two-position actuator engineered for precise zone control in hydronic heating and cooling systems. Built for high-demand residential and light commercial applications, this motor-driven actuator is specifically designed for normally open (N.O.) valve bodies, such as the Resideo VU52 and VU54 series. It features a robust spring return fail-safe mechanism, ensuring the valve returns to its default position within 6 seconds upon power loss—a critical requirement for maintaining system safety and preventing overheating. The unit is functionally identical to the ACT0518, offering a direct replacement solution for contractors servicing fan coil units, terminal reheat coils, and baseboard convectors. Utilizing a two-position SPST control signal, it provides reliable on/off operation without the complexity of modulation. Its compact, humidity-resistant construction is ideal for tight mechanical spaces, featuring a stainless steel case and aluminum cover for enhanced durability in environments with temperatures up to 125°F.
- Universal Compatibility: Engineered for seamless integration with VU52, VU53, and VU54 hydronic valve bodies, simplifying inventory for service crews.
- Rapid Fail-Safe Response: Dependable spring return operation takes only 6 seconds to close, protecting the system during electrical outages.
- Efficient Field Service: The one-button quick release and 3-point metal latch allow for actuator replacement without draining the system or disturbing plumbing.
- Contractor-Focused Design: Features a slotted conduit hole and 30-inch leads to accelerate wiring tasks in cramped fan coil cabinets.
- Reliable Zone Management: Maintains consistent flow control for hot or chilled water, optimizing HVAC zone valve performance and occupant comfort.
Common Questions:
- What is the primary application for this actuator? It is designed to control flow in fan coil units, convectors, and zone heating systems using normally open valve bodies.
- Does this model require a specific control signal? Yes, it operates on a standard 24V AC signal with a simple two-position (on/off) SPST configuration.
- Can I service the valve without removing the actuator? The actuator is designed for easy removal via a 3-point latch, allowing technicians to service or replace the motor without breaking into the hydronic loop.
