Resideo 40003916-011 Replacement Motor

The Resideo 40003916-011 Replacement Motor is a critical component for restoring the functionality of your hydronic heating system. Engineered specifically as a replacement actuator for V8043C series zone valves, this 24Vac synchronous motor ensures reliable cycling of 2-way, normally closed valve bodies. As a seasoned technician, you know that field reliability depends on precise fitment; this unit features a manual lever for manual opening during system filling or power loss, returning to the auto position upon restoration of power. The 18-inch leadwires provide ample length for clean routing to the control box or terminal strip, while the 60 Hz frequency matches standard North American electrical infrastructure. Designed for high-temperature environments, it maintains performance in ambient conditions up to 125°F. Rely on this Honeywell Home replacement head to maintain system pressure and flow control without the need to drain the entire loop, provided the existing valve body is compatible with the two-screw mounting pattern.

• Direct V8043C Compatibility: Seamlessly replaces powerheads on Honeywell and Resideo V8043C "1000" series zone valves.
• Manual Override Function: Integrated manual operating lever allows for system flushing and emergency operation without electrical signal.
• High-Temperature Resilience: Rated for maximum ambient temperatures of 125°F (52°C), suitable for demanding mechanical rooms.
• Simplified Installation: Features 18" leadwires and a two-screw mounting flange for rapid field replacement and reduced labor time.
• Reliable 24V Operation: Optimized for standard 24Vac hydronic control circuits, delivering consistent torque for positive valve closure.

Is the 40003916-011 compatible with V8043A valves?
Yes, this motor is widely used as a replacement powerhead for V8043A and V8043C series valves that utilize the standard two-screw motor attachment.

Do I need to drain the system to replace this motor?
No, if you are only replacing the zone valve actuator motor, the water seal remains intact within the valve body, allowing for a "dry" replacement.

What is the purpose of the 18-inch leads?
The extended 18-inch leadwires offer flexibility in wiring configurations, particularly in tight manifolds where the valve is distant from the zone controller.
