Io Hvac Controls RM-1612-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS RM-1612-BM is a rectangular zone damper designed for zoned HVAC duct systems. It features a bottom-mount configuration and ships with a 3-wire Belimo actuator rated for a 35-second stroke cycle. The damper blade assembly measures 16 inches wide by 12 inches tall, fitting standard rectangular duct openings of that size. The unit weighs 8.73 pounds. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system, where individual zones require independent airflow control through motorized blade operation.

This damper is suited for residential and light commercial forced-air zoning applications. The bottom-mount actuator placement is common in horizontal duct runs and ceiling plenum installations where top or side access is restricted. The included 3-wire Belimo actuator provides spring-return fail-safe operation, allowing the blade to return to a default position on power loss, which is standard practice in life-safety-aware zoning design. Compatible zone control panels that support 24-volt, 3-wire spring-return actuator signals are the typical pairing for this damper.

Key Features

• Rectangular blade damper sized for 16 inch by 12 inch duct openings
• Bottom-mount actuator position for installations with limited top or side clearance
• Includes 3-wire Belimo actuator with 35-second cycle time
• Spring-return actuator design provides fail-safe blade positioning on power loss
• Package dimensions of 18 inches wide, 20 inches tall, and 8 inches deep

Compatibility

Designed as an OEM-style replacement or new-install zone damper for residential and light commercial rectangular duct zoning systems using 24-volt, 3-wire spring-return actuator control signals.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with duct zoning systems and low-voltage wiring. Disconnect power to the air handler and zone control panel before beginning any wiring or duct work. Secure the damper to the duct with sheet metal screws and verify the blade moves freely through its full range before restoring power. Low-voltage control wiring must comply with NEC Class 2 circuit requirements.
