Resideo - Honeywell Home ZD18X14TZ Zone Control Damper

ZD18X14TZ Zone Control Damper by Resideo Honeywell Home is a rugged rectangular zone damper designed for parallel blade installations. With a nominal 18 x 14 inch duct size and extruded aluminum blades, this duct-ready damper delivers durable, smooth, and precise control for HVAC zoning systems.

Designed for reliability, it features spring return, fail-safe operation, and normally open behavior for safe shutoff scenarios. The 24V AC motor (8 VA) provides a 90-degree rotation for fast, accurate positioning with a 30-second power-open and 10-second spring-return timing. Wires connect to motor terminals M1 (Power), M6 (Common), and optional M4 LED indication for status.

Take control in challenging environments with a maximum static pressure of 1 inch WC and a pressure drop under 0.033 inch WC at 800 fpm, ensuring minimal airflow resistance. The damper operates across a broad temperature range (40–140°F) and is designed for side-mount motors, making it a versatile choice for parallel blade dampers in residential or commercial zoning.
