Resideo - Honeywell Home ZD24X12TZ Zone Control Damper

ZD24X12TZ Zone Control Damper from Resideo - Honeywell Home is a rectangular, parallel-blade zone damper designed for precise HVAC zoning. Built for 24x12 ductwork, its extruded aluminum blades deliver durable, low-friction operation and consistent zoning control.

With a fail-safe, normally open operation and a spring return, this damper provides reliable operation even during power loss. The 24V AC motor (8 VA) drives a 90-degree rotation, featuring 30-second power-open and 10-second spring-return timing to quickly respond to demand.

Key specs support robust performance in residential and light commercial systems, including a maximum static pressure rating of 1 inch WC, a pressure drop under 0.0329 inch WC at 800 FPM, and a temperature range of 40–140°F. The motor mounts on the side for easy installation and integrates with standard HVAC wiring for M1-Power, M6 Common, and optional LED indication.
