Io Hvac Controls HD-MOTOR-2 Damper Motor 24VAC

Product Description

The IO HVAC CONTROLS HD-MOTOR-2 is a 2-wire, 24-volt AC damper motor designed for zone control applications in forced-air HVAC systems. It mounts directly to round or rectangular damper shafts using an included 0.5-inch shaft collar, securing the actuator without additional adapters in most standard installations. The 2-wire design simplifies wiring by eliminating the need for a separate return or common wire, making it a practical choice for retrofit and new-construction zone damper installations alike. Licensed HVAC technicians and zoning specialists are the primary installers of this component.

The HD-MOTOR-2 is suited for residential and light-commercial zoning setups where 24-volt AC control signals are used to open or close supply or return air dampers. It is typically found in systems using zone control boards that switch 24-volt power to individual damper motors. The compact housing dimensions of 2.375 inches wide, 4.25 inches deep, and 3 inches tall allow installation in tight duct and plenum spaces where larger actuators would not fit.

Key Features

• 2-wire, 24-volt AC operation simplifies zone control wiring
• 0.5-inch shaft collar included for direct damper shaft mounting
• Compact housing: 2.375 x 3 x 4.25 inches fits tight plenum and duct spaces
• Lightweight at 1.162 pounds, reducing stress on damper blade assemblies
• Compatible with standard 24-volt zone control boards

Compatibility

Designed as an OEM-style replacement or new-installation damper actuator for residential and light-commercial forced-air zoning systems using 24-volt AC damper control wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect power to the air handler and zone control board before wiring or mounting the motor. Secure the shaft collar firmly to the damper shaft before restoring power, and verify full open and closed travel of the damper blade after installation. Follow all applicable local mechanical codes when modifying ductwork or zoning components.
