Io Hvac Controls RM-2812 Rectangular Zone Damper 28x12

Product Description

The IO HVAC CONTROLS RM-2812 is a rectangular zone damper designed for use in forced-air HVAC zoning systems. Measuring 28 inches by 12 inches, it ships with a Belimo actuator that operates on a 3-wire control circuit and cycles open or closed in approximately 35 seconds. Zone dampers like this one regulate conditioned airflow to individual zones, allowing a zoning controller to direct heating or cooling only where it is needed. Licensed HVAC technicians install this component as part of a multi-zone duct system, typically alongside a compatible zoning control panel and thermostat network.

This damper is intended for rectangular duct applications in residential and light-commercial forced-air systems. The 28-by-12-inch blade size fits a common duct dimension found in trunk-and-branch and plenum-style distribution layouts. The integrated Belimo actuator eliminates the need for a separate motor assembly, simplifying rough-in. It is well suited for new-construction zoning installations as well as retrofit zoning upgrades where the existing ductwork matches the damper opening size.

Key Features

• 28-inch by 12-inch rectangular blade fits standard duct openings of that dimension
• Integrated Belimo actuator included - no separate motor purchase required
• 3-wire control circuit compatible with standard zoning control panels
• 35-second actuator travel time provides controlled, gradual airflow modulation
• Ships as a complete damper-and-actuator assembly ready for installation

Compatibility

Designed as an OEM-style zone damper replacement or new-installation component for rectangular forced-air duct systems requiring a 28-inch by 12-inch opening with a 3-wire Belimo-style actuator. The raw_title references Rheem system compatibility; verify control panel wiring requirements before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Power down the air handler and disconnect the zoning control panel before making any wiring connections. The 3-wire actuator requires a dedicated control circuit from the zoning panel - consult the panel manufacturer wiring diagram before terminating leads. Follow all applicable local mechanical codes and manufacturer instructions for duct penetration, fastening, and low-voltage wiring clearances.
