Resideo vc6934zz11/u Floating Actuator SP3T 24V Ac

Product Description

The RESIDEO vc6934zz11/u is a direct-coupled floating actuator designed to control two-way and three-way hydronic valves in HVAC systems. It operates on a SP3T (tri-state) floating control signal at 24 volts AC, making it compatible with standard low-voltage building automation and zone control systems. The actuator features a double-insulated housing rated IP40 and ships with a five-foot plenum-rated cable and a flexible conduit adapter. A selectable electronic fail-safe allows the technician to configure the actuator for normally open or normally closed operation without additional components. Licensed HVAC technicians and mechanical contractors are the primary installers of this device.

This actuator is suited for residential and light commercial hydronic applications including central heating and cooling, fan coil units, radiators, and convectors. It is compatible with cold, warm, and hot water systems and supports media temperatures up to 203 degrees F. The actuator head can be installed without draining the system, reducing downtime during retrofits. It is rated for use exclusively with 3000 Series two-way and 7000 Series VC valve bodies.

Key Features

• SP3T tri-state floating control signal at 24 volts AC
• Selectable electronic fail-safe: configurable normally open or normally closed
• Double-insulated actuator body with IP40 protection class
• Five-foot plenum-rated cable included
• Actuator head installation does not require draining the system
• Self-alignment shaft adapter for simplified mounting
• Includes flexible conduit adapter

Compatibility

Rated for use with 3000 Series two-way and 7000 Series VC valve bodies only. Suitable for cold, warm, and hot water hydronic applications.

Installation Notes

Installation should be performed by a licensed HVAC or mechanical contractor in accordance with applicable local codes. De-energize the control circuit and confirm the system is at safe operating pressure before servicing the valve or actuator. The direct-coupled mounting design allows actuator replacement without draining the hydronic system, but always verify system pressure and temperature are within safe limits before beginning work. Confirm fail-safe position selection matches system design requirements before commissioning.
