Io Hvac Controls TD-2810-BM Rectangular Zone Damper 28x10

Product Description

The IO HVAC CONTROLS TD-2810-BM is a rectangular zone damper designed for forced-air zoning systems in residential and light commercial HVAC applications. Built to fit Trane and American Standard duct configurations, it uses a Belimo 3-wire actuator with a 60-second drive time for reliable, modulating airflow control. The damper installs in a bottom-mount configuration, positioning the actuator below the duct for access in tight ceiling or mechanical room installations. Licensed HVAC technicians install this component as part of multi-zone control systems where independent temperature management is required across separate areas of a structure.

This damper is suited for rectangular duct runs in residential zoning systems built around Trane and American Standard equipment. The 28-inch by 10-inch duct opening size matches common trunk and branch configurations in these systems. The Belimo 3-wire actuator provides both open and close control signals, making it compatible with standard zone control boards that output a switched 24-volt signal. Bottom-mount placement is common where overhead clearance is limited or where access from below is preferred during service.

Key Features

• 28 x 10 inch rectangular damper opening sized for Trane and American Standard duct systems
• Belimo 3-wire actuator with 60-second drive time for smooth, controlled blade travel
• Bottom-mount actuator position for installations with restricted overhead access
• 3-wire control wiring supports standard open, close, and common zone board outputs
• Compatible with 24-volt zone control systems typical in residential forced-air applications

Compatibility

Designed for use with Trane and American Standard rectangular duct systems requiring a 28 x 10 inch zone damper with a bottom-mount Belimo actuator configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Disconnect power to the zone control board and air handler before installing or wiring the damper actuator. Verify duct opening dimensions and mounting orientation before securing the damper frame to avoid binding the blade. Follow the zone control board manufacturer wiring diagram when connecting the 3-wire actuator leads.
