Resideo - Honeywell Home ZD8X12TZ Zone Control Damper

Zone Control Damper, the ZD8X12TZ from Resideo - Honeywell Home, delivers precise zoning with a rectangular damper featuring parallel blades for 8x12 inch ductwork. This durable unit uses extruded aluminum blades for smooth, long-lasting airflow control in residential or light commercial HVAC systems.

Designed for parallel blade operation, this damper offers a bottom-mounted 24V AC motor (60 Hz) delivering 71 in-oz of torque through a 90-degree rotation. It supports normally open operation with a spring return and time-limited action: 30 seconds to open when powered, 10 seconds to return on spring drive. With a mechanical visual position indicator and LED indication (optional M4), status is easy to read at a glance.
