Resideo VC8715ZZ11/U 2-position Valve Actuator 24V

Product Description

The RESIDEO VC8715ZZ11/U is a 2-position valve actuator designed for use with VC-series hydronic zone valves in low-voltage heating and cooling systems. Operating on 24 volts AC, it uses a single-pole single-throw (SPST) switching configuration to open and close the zone valve in response to a thermostat signal. The actuator mounts directly to a compatible VC-series valve body and provides reliable on/off flow control for zoned hydronic distribution. Licensed HVAC technicians and plumbers working on hot water heating systems are the primary installers of this component.

This actuator is suited for residential and light commercial hydronic zoning applications where individual room or zone temperature control is required. It is typically installed as part of a multi-zone hot water baseboard or radiant floor heating system, paired with a zone control board and low-voltage thermostat wiring. It is also used as a direct replacement actuator when the existing unit on a VC-series zone valve body has failed, allowing the valve body to remain in place.

Key Features

• 2-position (open/close) operation for straightforward on/off zone control
• SPST switching configuration compatible with standard low-voltage zone control boards
• 24-volt AC operating voltage matches common hydronic control system wiring
• Designed to mount directly on VC-series zone valve bodies without modification
• Compact actuator format allows installation in tight mechanical spaces

Compatibility

Designed as an OEM-style replacement actuator for VC-series hydronic zone valves in residential and light commercial low-voltage heating systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. De-energize the control system and shut off the hydronic circuit before removing or installing the actuator. Low-voltage wiring should be run and terminated in accordance with the thermostat and zone control board manufacturer instructions and applicable local codes. Do not apply line voltage to the actuator terminals, as the unit is rated for 24-volt AC control circuits only.
