Io Hvac Controls RM-2810-BM Zone Damper 28x10 Inch

Product Description

The IO HVAC CONTROLS RM-2810-BM is a rectangular bottom mount zone damper designed for forced-air zoning systems in residential and light commercial HVAC applications. It ships with a 35-second Belimo actuator wired on a 3-wire control circuit, allowing the damper blade to open and close on demand from a zone control panel. At 28 inches by 10 inches, this damper fits standard rectangular duct runs and is installed by licensed HVAC technicians as part of a multi-zone system. The bottom mount configuration places the actuator along the lower edge of the duct, which suits installs where overhead clearance is limited.

This damper is suited for rectangular supply or return duct branches in ducted forced-air systems where individual zone temperature control is required. The integrated Belimo actuator eliminates the need to source and mount a separate motor, reducing installation time. It is a common choice for zoning retrofits on existing duct systems as well as new construction zoning installations managed by a compatible zone control board.

Key Features

• 28-inch by 10-inch rectangular duct opening for standard trunk and branch duct sizing
• Bottom mount actuator placement for low-clearance duct installations
• Factory-integrated 35-second Belimo actuator for consistent, reliable blade travel
• 3-wire control circuit compatible with standard zone control panels
• Ships as a complete assembly - damper body and actuator included

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air zoning systems using 3-wire low-voltage actuator control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems and low-voltage control wiring. Power down the air handler and de-energize the zone control panel before wiring the actuator leads. Follow the zone control board manufacturer's wiring diagram for proper 3-wire open, close, and common terminal connections. Duct sealing around the damper frame is recommended to prevent air bypass.
