Io Hvac Controls HD-1814 Zone Damper 18x14 Inch 2 Wire

Product Description

The IO HVAC CONTROLS HD-1814 is a rectangular two-position zone damper with a 2-wire actuator, designed to control airflow in ducted HVAC zoning systems. The damper operates in two positions - open or closed - allowing independent temperature control across separate zones in a building. At 18 inches wide by 14 inches tall, this damper fits standard rectangular duct openings of that size. The 2-wire actuator simplifies wiring and reduces installation time compared to multi-wire designs. Licensed HVAC technicians install this component as part of a complete zone control system.

This damper is suited for residential and light commercial ducted forced-air systems where zone control is required. It installs inline within rectangular ductwork to regulate conditioned air delivery to individual zones. The two-position design is appropriate for single-stage heating and cooling applications where full open and full closed operation meets the zoning demand. It is commonly used in multi-zone retrofits and new construction zoning layouts.

Key Features

• Two-position (open/closed) operation for straightforward zone control
• 2-wire actuator reduces field wiring complexity
• 18 inch by 14 inch rectangular duct opening size
• Fits standard rectangular ductwork inline installations
• Suitable for residential and light commercial zoning applications

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC systems requiring two-position zone control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and ductwork. Power down the air handler and zone control panel before wiring the actuator. The damper must be installed in a section of rectangular ductwork that provides adequate clearance for actuator movement and service access. Follow local mechanical codes and manufacturer zone controller wiring instructions when integrating this damper into the zoning system.
