Resideo ARD16TZ Damper

The Resideo ARD16TZ Damper is a high-performance, single-blade 16-inch automatic round damper engineered specifically for technical precision in zoned HVACR systems. Built from rugged 22-gauge galvanized steel with a 20-gauge blade, this unit serves as the direct replacement for CRDS16, ensuring seamless integration into existing Honeywell Home TrueZONE systems. The integrated M847D-ZONE actuator provides a reliable power closed/spring return open fail-safe operation, essential for maintaining airflow during power interruptions. Designed for two-wire 24Vac installation, the motor features push-in terminals for rapid field wiring and an adjustable range stop to fine-tune minimum or maximum positions. With a leakage rating of less than 1% at 0.5 inches wc and a maximum static pressure capacity of 1.0 inch wc, this zone control damper minimizes bypass air while optimizing thermal delivery across multiple residential or light commercial zones.

Key Benefits for Contractors:

• Universal Compatibility: Serves as the designated legacy upgrade and replacement for CRDS16 round dampers.
• Structural Durability: Galvanized steel construction with a heavy-duty blade and shaft for longevity in high-cycle applications.
• Installation Efficiency: Two-wire connectivity with fail-safe spring return simplifies wiring for TrueZONE panel setups.
• Performance Precision: Gasket-sealed blade ensures a tight shut-off, reducing energy loss and improving system Delta-T.
• Field Flexibility: Includes a mechanical position indicator and reversible actuator for various mounting orientations.

Common Technical Questions:

Is the ARD16TZ compatible with 3-wire zoning panels?
This is a 2-wire motor designed for power-to-close and spring-to-open logic. While optimized for 2-wire systems like the HZ322 or HZ432, it can be integrated into 3-wire layouts with the appropriate relay or by identifying the specific power-close terminals.

Can I convert this for fresh air intake applications?
Yes. While shipped as a normally open damper, the actuator can be field-converted to power-open/spring-closed configuration for combustion air or ventilation intake requirements.

How do I set the minimum airflow using the range stops?
The actuator housing features integrated adjustable range stops. By loosening the set screw, you can manually define the blade's travel limit to maintain a constant minimum bleed of air into the zone.
