Resideo ARD14TZ Damper

The Resideo ARD14TZ is a 14-inch automatic round damper designed for precision airflow control in residential and light commercial HVAC systems. This 24Vac power closed spring return open damper provides a default open fail-safe, ensuring ventilation or zone cooling remains active during power loss. Built with heavy-duty galvanized steel, the ARD14TZ motorized damper features a two-position actuator that is easily reversible for field flexibility. As a direct replacement for the RDS-14 and CRDS14, this unit integrates seamlessly into existing ductwork using a single-blade design and synthetic bushings to minimize mechanical friction. The sealed motor housing protects internal components from dust and debris, maintaining torque performance over extended cycles. On-board adjustable range stops allow technicians to fine-tune minimum and maximum blade positioning, optimizing HVAC zone control and preventing excessive static pressure buildup in high-velocity systems.

Key Benefits for Technicians

• Direct Replacement: Drop-in compatibility for discontinued RDS-14 and CRDS14 models simplifies HVAC damper replacement.
• Field Reversibility: The actuator can be easily reconfigured to change the orientation from power closed to power open.
• Visual Position Indicator: External markings allow for immediate verification of blade status without dismantling the duct.
• Robust Actuator: High-torque 24V synchronous motor ensures reliable closure against high static pressure environments.
• Simplified Wiring: Terminal block connections streamline damper installation and troubleshooting in tight spaces.

Common Technical Questions

Can the ARD14TZ be used with any 24V zone panel?
Yes, this 14 inch zone damper is compatible with most standard HVAC zone control systems that provide a constant 24Vac signal to actuate the motor.

Is this damper suitable for vertical duct runs?
The Resideo ARD series is designed for multi-positional installation, though ensuring the actuator remains accessible for service is best practice.

How do I adjust the minimum airflow?
The actuator features a manual set screw that acts as a physical stop, allowing you to bleed air into a zone even when the damper is signaled to close.
