Io Hvac Controls RM-1412-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS RM-1412-BM is a rectangular zone damper designed for zoned HVAC distribution systems. Measuring 14 inches by 12 inches, this damper features a bottom-mount configuration with a 3-wire Belimo actuator rated for a 35-second stroke cycle. Zone dampers like this one regulate airflow through individual duct branches, allowing independent temperature control across multiple zones in a single forced-air system. The 3-wire actuator provides both open and close control signals, making it compatible with standard zone control boards that require positive positioning. Licensed HVAC technicians typically handle installation as part of a zoned duct system design or retrofit.

This damper is suited for residential and light commercial forced-air HVAC applications where zoning is required. The 14-inch by 12-inch rectangular duct size fits common trunk-and-branch or extended-plenum duct configurations. The bottom-mount actuator placement accommodates installations where side or top access to the damper body is restricted. It is commonly installed in new construction zoning projects or retrofitted into existing ductwork when adding zone control capability to a split system or air handler.

Key Features

• Rectangular damper body sized at 14 inches by 12 inches for standard duct fitment
• Bottom-mount Belimo actuator allows installation in space-restricted duct locations
• 3-wire actuator wiring supports positive open and close control from zone control boards
• 35-second actuator cycle time provides smooth, reliable damper positioning
• Designed for integration into multi-zone forced-air residential and light commercial systems

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular duct systems requiring a 14-inch by 12-inch opening with a bottom-mount 3-wire actuator configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes. Power down the air handler and zone control panel before wiring the actuator. Secure the damper body into the duct opening using sheet metal screws and seal all edges with foil tape to prevent air bypass. Connect the 3-wire actuator leads to the corresponding terminals on the zone control board per the control board manufacturer wiring diagram.
