Io Hvac Controls RM-3008-BM Zone Damper 30x8 Belimo 3-wire

Product Description

The IO HVAC CONTROLS RM-3008-BM is a rectangular bottom mount zone damper designed for ducted HVAC zoning systems. It ships with a 35-second Belimo actuator wired in a standard 3-wire configuration, allowing the damper blade to open and close in response to zone thermostat or zone control board signals. Measuring 30 inches wide by 8 inches in duct size, this damper fits rectangular ductwork and mounts from the bottom of the duct. At 9.73 pounds, it is built for permanent installation by licensed HVAC technicians working on residential or light-commercial zoning projects.

This zone damper is used in forced-air HVAC systems where independent temperature control is required across multiple zones. The bottom mount design suits installations where duct access is available from below, a common scenario in basement, crawlspace, and overhead mechanical room layouts. The integrated Belimo actuator eliminates the need to source and match a separate motor, simplifying the installation process. It is compatible with most standard 24-volt zone control boards that support 3-wire spring-return or 3-wire on/off actuator wiring.

Key Features

• 30x8 inch rectangular duct size fits common residential and light-commercial duct runs
• Bottom mount design for installations requiring access from below the duct
• Factory-installed Belimo actuator with 35-second stroke time
• 3-wire actuator wiring compatible with standard 24-volt zone control systems
• Self-contained assembly reduces field component matching and wiring time

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems using 24-volt, 3-wire actuator control. The raw_title references Rheem zoning applications; confirm compatibility with your specific zone control board before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control board before wiring the actuator. Verify the zone control board supports a 3-wire actuator signal before connecting. Duct connections should be sealed with approved mastic or foil tape per applicable mechanical codes to prevent air bypass around the damper frame.
