Io Hvac Controls CD-2012 Rectangular Zone Damper 20x12

Product Description

The IO HVAC CONTROLS CD-2012 is a rectangular zone damper designed for use in ducted HVAC zoning systems. It measures 20 inches by 12 inches and ships with a Belimo 3-wire actuator pre-installed, making it a ready-to-install assembly for residential and light commercial zoning applications. The Belimo actuator provides precise, reliable airflow control and is compatible with standard zone control boards that output 24-volt signals. Licensed HVAC technicians performing zone system installations or replacements will find this a direct-fit unit for supported duct configurations.

This damper is specified for use in Carrier and Bryant zoning systems where a 20-inch by 12-inch rectangular duct opening is present. It fits into new construction and retrofit applications where the duct layout calls for a damper in a standard rectangular trunk or branch run. The Belimo 3-wire actuator design allows for both open and closed end-position feedback, which is commonly required by zone control panels for proper system sequencing and fault detection.

Key Features

• 20 x 12 inch rectangular damper for use in matching duct openings
• Includes Belimo 3-wire actuator for 24-volt zone control integration
• Pre-assembled unit reduces installation time in the field
• 3-wire actuator supports end-switch feedback for zone panel compatibility
• Designed for residential and light commercial ducted zoning systems

Compatibility

Designed for use in Carrier and Bryant rectangular zone damper applications requiring a 20 x 12 inch damper with a Belimo 3-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handling unit and de-energize the zone control panel before beginning installation. Verify that the duct opening dimensions match the damper size before securing the unit in place. Low-voltage wiring to the zone control board should be run and connected per the zone panel manufacturer wiring diagram and applicable local codes.
