Resideo ZD22X16TZ Damper

The Resideo ZD22X16TZ is a professional-grade parallel blade zone damper designed for precision airflow control in residential and light commercial forced-air systems. Built with a heavy-duty extruded aluminum frame and blades, this 22x16 rectangular damper ensures structural integrity and low-leakage performance. It utilizes a 24Vac synchronous motor mounted on the 16-inch side, operating in a power closed/spring return open configuration to maintain a fail-safe, normally-open position. The spring return actuator provides roughly 71 inch-ounces of torque, ensuring reliable movement even under static pressures reaching 1.0 inch WC. This unit is fully compatible with TrueZONE and other electronic zoning panels, featuring a two-wire installation and a mechanical visual position indicator for easy field diagnostics. The parallel blade design provides superior airflow regulation and quieter operation compared to standard single-blade alternatives, making it a staple for contractors prioritizing long-term HVAC system efficiency.

• Fail-Safe Operation: The normally-open spring return ensures airflow continues if power is lost, preventing coil freeze-ups or heat exchanger overheating.
• Industrial Construction: Features extruded aluminum blades and frames for maximum corrosion resistance and durability in high-humidity environments.
• Precise Control: Equipped with adjustable range stops to fine-tune minimum and maximum blade positions for balanced airflow.
• Effortless Integration: Simplified 24V two-wire terminal connection reduces installation time on Honeywell zoning systems.
• Reduced Maintenance: Utilizes Kevlar gearing within the motor assembly to decrease internal friction and extend the service life of the actuator.

Is the motor replaceable on the ZD22X16TZ?
Yes, the actuator is a modular component. If the synchronous motor fails, it can be swapped without removing the entire damper frame from the ductwork.

Can this damper be installed vertically?
Absolutely. The Resideo ZD series is designed for multi-orientation installation, meaning it functions reliably whether mounted in a vertical or horizontal duct run.

What happens if the 24V signal is lost?
Because this model is spring return open, the internal spring mechanism will immediately pull the blades to the fully open position if power is interrupted, ensuring the zone is not starved for air.
