Resideo ZD24X12TZ Damper

The Resideo ZD24X12TZ is an industrial-grade parallel blade zone damper designed for precision airflow regulation in forced-air zoning systems. Built with a robust extruded aluminum frame and matching blades, this 12-inch high by 24-inch wide rectangular unit utilizes a 24Vac synchronous motor mounted on the 12-inch side for high-torque performance. This two-position damper is configured for power closed/spring return open operation, ensuring a fail-safe open state during power loss for critical ventilation needs. Engineered for low-leakage performance, the parallel blade design provides tight shut-off and is rated for operation in systems with static pressures up to 1 in. wc. The integrated motor features adjustable mechanical range stops and a visual position indicator, making it compatible with Honeywell TrueZONE panels and other standard electronic zoning controllers.

• Durable Construction: Features a corrosion-resistant extruded aluminum frame and parallel blades for long-term reliability in varying duct environments.
• Fail-Safe Operation: The spring return open mechanism ensures the damper defaults to the open position, maintaining airflow if power is interrupted.
• Contractor-Friendly Install: Simplify setup with two-wire push-in terminals and a synchronous motor that supports multi-poise mounting orientations.
• Precision Control: Utilizes adjustable range stops to calibrate minimum and maximum air bleeds, fulfilling specific residential or light commercial zoning requirements.
• High Performance: Rated for low-leakage (less than 1% at 0.5 in. wc) and capable of handling up to 1.0 in. wc static pressure.

Common Questions

Can this damper be used for fresh air intake?
The Resideo ZD24X12TZ is a power closed/spring return open unit, meaning it remains open when de-energized. While it can be used for ventilation, most fresh air applications require a "normally closed" damper like the EARD series to prevent unconditioned air from entering when the system is off.

Is the motor replaceable without removing the entire damper?
Yes, the resideo zone motor is designed for easy field replacement. It attaches directly to the damper shaft with a single set screw, allowing for fast maintenance without disrupting the ductwork connection.

Does this unit support a position-feedback LED?
The motor terminal block includes an optional M4 terminal which provides LED indication for damper status when integrated with compatible zone control boards or remote indicators.
