Resideo - Honeywell Home ZD8X20TZ Zone Control Damper

The Zone Control Damper ZD8X20TZ by Resideo – Honeywell Home delivers precise airflow control for your HVAC system. This Rectangular, Parallel Blade damper is designed for 8 x 20 ductwork and built with extruded aluminum blades for lasting durability. Featuring fail-safe operation with spring return and a mechanical visual position indicator, it offers reliable performance and quick status checks in tight ceiling or mechanical spaces.

Powered by a 24V AC motor at 60 Hz with 71 in-oz torque, it provides smooth, dependable actuation and a 90-degree rotation for full openness. With a temperature range of 40 to 140°F and a maximum static pressure rating of 1 in WC, this damper maintains performance in variable building conditions. Its low pressure drop (<0.0329 in WC at 800 fpm) helps keep energy use minimal, while the bottom-mounted motor and power-closed, spring-open design ensure simple integration.

Wiring to motor terminals M1-Power, M6-Common, with optional M4 LED indication.
