Io Hvac Controls RM-2608 Rectangular Zone Damper 26x8

Product Description

The IO HVAC CONTROLS RM-2608 is a rectangular zone damper designed for use in ducted HVAC zoning systems. It ships with a 3-wire Belimo actuator that operates on a 35-second stroke cycle, allowing the damper blade to open and close smoothly in response to zone controller signals. At 26 inches wide by 8 inches tall, this damper fits standard rectangular duct runs where airflow to individual zones must be independently controlled. Licensed HVAC technicians install this component as part of a multi-zone forced-air system, typically alongside a zone control board and low-voltage thermostat wiring.

This damper is suited for residential and light-commercial zoning applications where rectangular duct configurations are standard. It is commonly installed in supply duct branches feeding individual zones, enabling the system to direct conditioned air only where a call for heating or cooling exists. The included Belimo actuator eliminates the need to source a separate motor, making it a ready-to-install assembly for new construction and retrofit zoning projects alike.

Key Features

• 26 x 8 inch rectangular form factor fits standard duct openings
• Integrated 3-wire Belimo actuator included - no separate motor required
• 35-second actuator cycle time provides smooth, controlled blade travel
• 3-wire control interface compatible with standard zone control boards
• Ready-to-install assembly suited for both new construction and retrofit applications

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air zoning systems. Compatible with 3-wire zone control boards that support standard open/close actuator wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage control wiring and duct fabrication. Power down the zone control panel and air handler before making any electrical connections. Secure the damper in the duct section before connecting the actuator leads to the zone board per the controller manufacturer wiring diagram. Follow all applicable local mechanical and electrical codes during installation.
