Io Hvac Controls TD-2418-BM Rectangular Zone Damper 24x18

Product Description

The IO HVAC CONTROLS TD-2418-BM is a rectangular zone damper designed for zoned HVAC duct systems. It measures 24 x 18 inches and is built to regulate airflow in individual zones, allowing independent temperature control across multiple areas of a building. The damper ships with a bottom-mount Belimo 3-wire actuator that operates on a 60-second cycle time. Licensed HVAC technicians install this unit as part of a multi-zone control system, typically alongside a zone control board, thermostat wiring, and a bypass damper where required. The assembly is suited for residential and light commercial ducted forced-air applications.

This damper is configured specifically for Trane and American Standard rectangular duct applications. The 24 x 18 inch duct opening size fits common trunk-line and branch-duct installations in residential and light commercial systems. The bottom-mount actuator orientation is intended for installations where top or side mounting is not accessible. The Belimo 3-wire actuator allows for proportional or open/close control depending on the control system in use.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned duct systems and low-voltage control wiring. Shut down the air handler and de-energize all control wiring before installing or servicing the damper. Verify actuator wiring matches the zone control board terminals before energizing. Follow local mechanical codes and manufacturer wiring diagrams for proper 3-wire actuator hookup.
