Io Hvac Controls TD-2014 Rectangular Zone Damper 20x14

Product Description

The IO HVAC CONTROLS TD-2014 is a rectangular zone damper designed for residential and light commercial HVAC zoning systems. It controls airflow to individual zones by opening and closing on demand from a zone control panel or thermostat. The unit ships with a Belimo 3-wire actuator that cycles in 60 seconds, providing reliable modulation without hunting or overshoot. The damper blade assembly measures 20 x 14 inches and is built to fit standard rectangular duct openings in forced-air systems. HVAC technicians and sheet metal installers are the primary trades handling this component.

This damper is used in zoned forced-air heating and cooling systems where multiple thermostats independently control airflow to separate areas of a building. It is specifically dimensioned and configured for compatibility with Trane and American Standard zoning systems. Typical installation scenarios include residential retrofits where a single-stage furnace or air handler is divided into two or more independently controlled zones. The 60-second Belimo actuator is wired directly to the zone control board using a standard 3-wire configuration.

Key Features

• 20 x 14 inch rectangular damper blade sized for standard duct openings
• Belimo 3-wire actuator included, 60-second open and close cycle
• Designed for compatibility with Trane and American Standard zoning systems
• Low-voltage actuator reduces wiring complexity at the control board
• Rectangular form factor suits common rectangular supply trunk and branch ducts

Compatibility

Dimensioned and configured for use with Trane and American Standard rectangular duct zoning systems. Verify duct opening dimensions and zone control board wiring requirements before installation.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified sheet metal installer. Power down the air handler and zone control panel before wiring the actuator. The actuator low-voltage wiring should be routed and terminated in accordance with NEC Class 2 circuit requirements. Do not force the damper blade manually while the actuator is energized.
