Io Hvac Controls TD-2608 Rectangular Zone Damper 26x8

Product Description

The IO HVAC CONTROLS TD-2608 is a rectangular zone damper designed for zoned HVAC duct systems requiring precise airflow control. Built to fit 26 x 8 inch duct openings, this damper ships with a 60-second Belimo 3-wire actuator already mounted, eliminating the need to source a separate actuator on the job. The 3-wire actuator configuration supports both open and closed end-switch feedback, which is essential for zone control boards that require proof-of-position signaling. At 9 pounds, the assembly is robust enough for commercial-style residential installations. HVAC technicians working on multi-zone forced-air systems will find this a direct-fit solution that reduces labor time during rough-in or changeout work.

This damper is intended for rectangular supply or return duct applications in zoned forced-air systems. It is specifically referenced for use with Trane and American Standard HVAC equipment, making it well suited for service and replacement work on those platforms. Typical installation scenarios include residential multi-zone retrofits, new construction zone system builds, and damper replacement on existing zone control setups. The damper fits into the ductwork inline and connects to the zone control board via the Belimo actuator wiring harness.

Key Features

• Factory-mounted 60-second Belimo 3-wire actuator included - no separate actuator purchase required
• 3-wire actuator supports open and closed end-switch feedback for zone board compatibility
• 26 x 8 inch duct opening size for rectangular duct applications
• Referenced compatibility with Trane and American Standard forced-air systems
• 9-pound assembly weight indicates heavy-duty construction suitable for permanent installation

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning applications. Intended as a zone damper replacement or new-install component for forced-air systems using compatible IO HVAC CONTROLS or equivalent zone control boards that accept 3-wire Belimo actuator wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control system before cutting into ductwork or making actuator wiring connections. The actuator low-voltage wiring must be run and connected per the zone control board manufacturer's wiring diagram. Consult local mechanical codes for duct penetration and fastener requirements when securing the damper frame to the duct.
