Io Hvac Controls TD-1806-BM Rectangular Zone Damper 18x6

Product Description

The IO HVAC CONTROLS TD-1806-BM is an 18 x 6 inch rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. It ships with a Belimo 3-wire actuator mounted on the bottom of the damper body, providing a 60-second open and close cycle time. The actuator drive integrates directly with standard zone control boards that output a 3-wire signal, making it a ready-to-install assembly for technicians building or servicing multi-zone ducted air systems. Licensed HVAC technicians are the primary installers of this component.

This damper is built to fit Trane and American Standard rectangular duct applications calling for an 18 x 6 inch damper. It is suited for residential forced-air zoning installations where individual rooms or zones require independent temperature control. The bottom-mount actuator configuration is well suited for horizontal duct runs where top or side access is limited. The 60-second cycle time is compatible with most residential zone control panels that expect standard spring-return or non-spring-return 3-wire actuator timing.

Key Features

• 18 x 6 inch rectangular damper sized for Trane and American Standard duct applications
• Includes Belimo 3-wire actuator for reliable, field-proven actuation
• 60-second open and close cycle time compatible with standard zone control panels
• Bottom-mount actuator position for installations with limited top or side clearance
• Ships as a complete, pre-assembled damper and actuator unit ready for installation

Compatibility

Designed as a replacement or new-installation zone damper for Trane and American Standard rectangular duct systems requiring an 18 x 6 inch damper with a 3-wire Belimo actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems and low-voltage control wiring. Shut down the air handler and de-energize all low-voltage control wiring before beginning installation. Secure the damper body to the duct section per the duct manufacturer's sheet metal practices before connecting the actuator wiring to the zone control board. Consult the zone panel manufacturer's wiring diagram to confirm correct 3-wire actuator terminal assignments before powering the system.
