Io Hvac Controls CD-2814 Rectangular Zone Damper 28x14

Product Description

The IO HVAC CONTROLS CD-2814 is a rectangular zone damper engineered for use in residential and light commercial zoning systems. It measures 28 inches by 14 inches and ships with a Belimo 3-wire actuator pre-mounted, allowing licensed HVAC technicians to complete zone installations without sourcing a separate actuator. The 3-wire actuator configuration supports standard open-close-common wiring used in most zone control board applications. At 14 pounds, this is a substantial damper suited for larger trunk or branch duct runs where airflow control is critical to zone system performance.

This damper is designed for forced-air zoning installations in Carrier and Bryant duct systems where rectangular duct geometry is present. It fits trunk lines and main branch ducts in residential and light commercial builds where multiple zones require independent airflow regulation. HVAC contractors installing or retrofitting zone control systems will find the integrated Belimo actuator eliminates a common field assembly step. The damper is appropriate for low-voltage zone control board systems that use a standard 3-wire actuator signal.

Key Features

• 28-inch by 14-inch rectangular duct opening - sized for larger trunk and branch runs
• Belimo 3-wire actuator included and pre-mounted at the factory
• 3-wire open-close-common actuator wiring compatible with standard zone control boards
• Designed for Carrier and Bryant rectangular duct zoning applications
• Ships as a complete assembly - no separate actuator sourcing required

Compatibility

Designed as an OEM-style zone damper replacement and new-install component for Carrier and Bryant rectangular duct zoning systems using a Belimo 3-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Disconnect power to the air handler and zone control board before wiring the actuator. Secure the damper into the duct using sheet metal screws and verify the blade moves freely through its full range of travel before restoring power. Follow all applicable local mechanical codes and manufacturer zone board wiring diagrams when making low-voltage actuator connections.
