Resideo VC8114ZZ11/U Low-voltage Valve Actuator 24 Vac

Product Description

The RESIDEO VC8114ZZ11/U is a two-position, low-voltage actuator designed for use with VC Series hydronic zone valves. Operating on 24 VAC, it opens and closes the valve in response to a two-position control signal from a low-voltage thermostat or zone controller. The actuator drives 2-way and 3-way valve bodies to regulate flow in hydronic heating and cooling systems. It is installed by licensed HVAC technicians and plumbers working on hydronic zone control applications where reliable on/off flow management is required.

This actuator is suited for residential and light commercial hydronic systems where zone-by-zone temperature control is managed through low-voltage wiring. Typical installations include hot water heating systems, chilled water cooling systems, and fan coil unit applications. The VC8114ZZ11/U pairs with VC Series valve bodies in 2-way or 3-way configurations, making it a practical replacement or service component for existing zone valve assemblies.

Key Features

• Two-position control signal for simple open/close valve operation
• 24 VAC supply voltage compatible with standard low-voltage HVAC controls
• Compatible with both 2-way and 3-way VC Series valve body configurations
• Designed as a service-replacement actuator for VC Series zone valves
• Suited for hydronic heating and cooling zone control applications

Compatibility

Designed for use with RESIDEO VC Series zone valve bodies in 2-way and 3-way configurations. Consult the valve body documentation to confirm actuator-to-body fit before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed plumber familiar with low-voltage hydronic zone control systems. Shut off the hydronic system and de-energize all control wiring before removing or installing the actuator. Verify that the supply voltage at the control circuit is 24 VAC before connecting the actuator. Follow all applicable local mechanical and electrical codes during installation.
