Resideo - Honeywell Home ZD10X20TZ Zone Control Damper

The Zone Control Damper from Resideo Honeywell Home ZD10X20TZ delivers precise airflow control for HVAC zoning. This rectangular damper, featuring a parallel blade design, fits a 10" x 20" duct and is built for durable, long-lasting performance.

With spring return and fail-safe operation, it maintains safety and reliability even during power fluctuations. The bottom-mounted motor offers 24V AC operation (60 Hz) with 71 in-oz torque, enabling fast, accurate positioning across a temperature range of 40 to 140 F. The design supports a maximum static pressure of 1 in WC and delivers a low pressure drop (<0.0329 in WC at 800 fpm). A mechanical visual position indicator and LED indication help installers and technicians verify damper status at a glance. Wires connect to motor terminals M1-Power, M6 Common, with M4 as an optional LED line for diagnostics.
