Io Hvac Controls TD-1606-BM Rectangular Zone Damper 16x6

Product Description

The IO HVAC CONTROLS TD-1606-BM is a rectangular zone damper assembly built for 16 x 6 inch ductwork in residential and light commercial zoned HVAC systems. It ships with a Belimo 3-wire actuator mounted on the bottom of the damper body. The actuator operates on a 60-second drive time, providing controlled airflow modulation in response to zone thermostat calls. Licensed HVAC technicians install this assembly as part of a multi-zone ducted system, replacing failed dampers or commissioning new zone control layouts. The unit weighs 6 pounds and carries overall package dimensions of 14 inches wide, 19 inches tall, and 8 inches deep.

This damper is designed for use in Trane and American Standard zoning applications where rectangular duct dampers are required. It is suited for single-stage or multi-stage forced-air systems using zone control boards that output 24-volt signals to modulating or on/off actuators. Typical installations involve trunk-and-branch duct layouts where individual zones require independent airflow control. The bottom-mount actuator configuration is appropriate where side-mount clearance is limited or where the bottom orientation aligns with the existing duct run access.

Key Features

• Belimo 3-wire actuator included, factory-mounted in the bottom position
• 60-second drive time for smooth, controlled damper blade travel
• Sized for 16 x 6 inch rectangular duct openings
• Compatible with Trane and American Standard zoning control systems
• Compact package dimensions: 14 inches wide, 19 inches tall, 8 inches deep

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning systems requiring a 16 x 6 inch damper with a bottom-mount 3-wire Belimo actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Power down the zone control board and air handler before connecting or disconnecting any actuator wiring. Confirm duct opening dimensions and actuator orientation before final mounting to avoid rework. Follow applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, when routing actuator wiring back to the zone control board.
