Resideo - Honeywell Home ZD12X20TZ Zone Control Damper

ZD12X20TZ Zone Control Damper from Resideo/Honeywell Home delivers precise zoning control for 12x20 inch ductwork. This rectangular, parallel blade damper is designed to regulate airflow with reliability in HVAC systems, ensuring balanced cooling or heating across zones.

Constructed with an extruded aluminum blade, it uses a bottom-mounted 24V AC motor rated at 60 Hz with 8 VA, delivering 90° travel and 71 in-oz of torque. The integrated timing offers 30 seconds to power-open and 10 seconds to spring-return, enabling fast, predictable operation. The unit tolerates temperatures from 40 to 140 °F and maintains a low pressure drop (<0.033 in. wc at 800 fpm) with a maximum static pressure of 1 in. wc.

Designed for reliability, it features fail-safe, normally open operation and a mechanical visual position indicator. Optional LED indication via M4 wiring helps confirm damper status in complex systems. Perfect for parallel blade damper applications in residential or light commercial zoning projects.
