Io Hvac Controls TD-1806 Rectangular Zone Damper 18x6

Product Description

The IO HVAC CONTROLS TD-1806 is an 18 x 6 inch rectangular zone damper designed for zoned HVAC distribution systems. It ships with a Belimo 3-wire actuator that operates on a 60-second cycle time, providing controlled airflow modulation within ducted supply or return runs. The damper body is sized to fit standard rectangular duct openings and is compatible with Trane and American Standard zoning applications. Licensed HVAC technicians and zoning system installers are the primary installers of this component.

This zone damper is used in residential and light commercial forced-air zoning systems where multiple zones require independent temperature control. It is suited for new zoning installations and retrofit applications within Trane and American Standard duct systems. The 18 x 6 inch face size fits standard rectangular trunk or branch duct configurations. The integrated Belimo 3-wire actuator allows the damper to be driven open, closed, or to a proportional position depending on the zone control panel's output signal.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. De-energize the zone control panel and air handler before installing or wiring the actuator. Secure the damper body to the duct section using sheet metal screws and seal all connections per applicable mechanical codes. Verify actuator wiring against the zone control panel's 3-wire output terminals before restoring power.
