Resideo ZD16X14TZ Damper

The Resideo ZD16X14TZ is a professional-grade parallel blade zone damper designed for demanding forced-air zoning applications. This 16" wide by 14" high rectangular damper utilizes a 24Vac power closed/spring return open configuration, ensuring fail-safe ventilation should power be lost. The integrated synchronous motor is mounted on the 14" side, providing high-torque operation to move the parallel blades efficiently against static pressure. Engineered for seamless integration with Honeywell Home zoning systems, the ZD16X14TZ features a mechanical adjustment for setting minimum or maximum positions, allowing technicians to fine-tune HVAC duct airflow and maintain system balance. The heavy-duty galvanized steel construction and reinforced blade design minimize air bypass and prevent rattling. For contractors installing multi-zone HVAC systems, this damper offers the reliability needed for two-position airflow control in both residential and light commercial trunk lines, ensuring precise temperature regulation across all zones.

Key Benefits for Technicians

• Fail-Safe Operation: The spring-return open design ensures the damper defaults to the open position during power failures to prevent equipment overheating.
• Precision Airflow Management: Parallel blade orientation provides lower pressure drops and more linear flow characteristics in larger rectangular ducts.
• Simplified Installation: The synchronous motor includes easy-to-wire terminals and a manual position indicator for rapid troubleshooting in the field.
• Robust Construction: Built with high-gauge galvanized steel to withstand high-velocity HVAC air distribution without warping or fatigue.
• Direct Compatibility: Engineered specifically for Honeywell zone control panels, reducing the need for secondary relays or complex wiring harnesses.

Common Installation & Technical Questions

Can the ZD16X14TZ be used as a bypass damper?
While primarily designed for zone control, this unit can function in bypass applications if the 24V signal is managed by a static pressure controller. However, for most modulated bypass needs, a dedicated barometric or constant pressure damper is recommended.

What is the power draw for the synchronous motor?
The motor operates on 24V AC and typically draws approximately 6-8 VA during the power-closed cycle. Ensure your zoning transformer is sized correctly to handle the cumulative VA load of all dampers in the system.

Is the actuator field-replaceable?
Yes, the actuator assembly can be replaced without removing the entire damper frame from the ductwork, minimizing downtime during service calls for HVAC zone maintenance.
