Io Hvac Controls RM-2214 Rectangular Zone Damper 22x14 in

Product Description

The IO HVAC CONTROLS RM-2214 is a rectangular zone damper sized at 22 x 14 inches, designed for use in zoned HVAC duct systems. It ships with a 3-wire Belimo actuator that operates on a 35-second stroke cycle, providing controlled airflow modulation across independently zoned areas. The damper regulates conditioned air delivery to specific zones, allowing each zone to be opened or closed based on thermostat demand. Licensed HVAC technicians install this component as part of a multi-zone forced-air system, integrating it into the ductwork between the air handler and the zone outlets.

This damper is suited for residential and light commercial zoning applications where rectangular duct configurations are used. The 22 x 14 inch opening fits standard rectangular trunk or branch duct runs. The Belimo actuator provides reliable, repeatable actuation cycles compatible with most zone control panels that support 3-wire floating or spring-return wiring configurations. It is typically installed in accessible ceiling, wall, or mechanical room ductwork runs as part of a complete zoning system.

Key Features

Compatibility

Designed as an OEM-style zone damper replacement or new-installation component for rectangular duct zoning systems compatible with 3-wire actuator zone control panels.

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 wiring or mounting the damper. Secure the damper into the duct run using sheet metal screws and seal edges with foil tape per standard duct installation practice. Verify actuator wiring matches the zone control panel specifications before restoring power.
