Resideo ARD9TZ Damper

The Resideo ARD9TZ is a 9-inch automatic round damper engineered specifically for high-efficiency forced air zoning systems that require reliable airflow control. Operating on 24Vac, this two-position damper uses a power closed/spring return open actuator, ensuring a fail-safe open position during power loss to maintain system circulation. This model is the professional-grade direct replacement for ARD9TZ/U, RDS-9, and CRDS09 legacy dampers. Constructed from heavy-duty galvanized steel, it features a single-blade design that seals tightly against a dedicated gasket to achieve less than 1% leakage at 0.5 in. WC. The TrueZONE integrated design includes push-in terminals and adjustable range stops for precise airflow balancing, while the mechanical position indicator provides clear visual confirmation of the blade status. Designed to handle static pressures up to 1-inch wc, the ARD9TZ delivers the durability and quiet operation expected in HVACR commercial and residential applications.

• Universal Compatibility: Serves as a drop-in replacement for RDS-9 and CRDS09, minimizing modification time on retrofits.
• Superior Seal: The galvanized steel blade and gasket system ensure minimal leakage for improved energy efficiency.
• Efficient Installation: Features two-wire 24V wiring with push-in terminals compatible with Resideo TrueZONE panels.
• Fail-Safe Logic: The spring return open mechanism ensures maximum airflow if the 24Vac actuator loses power.
• Visual Troubleshooting: Integrated LED indicators and a mechanical position indicator allow for rapid diagnostic checks.

• Is this damper reversible? Yes, the ARD9TZ actuator can be field-converted to a power-open/spring-closed configuration if your specific zone requires it.
• What are the wiring requirements? Use 24Vac 60Hz power; the unit consumes 6-8 VA when energized. It is best to use solid wire for the push-in terminals for the most secure connection.
• Can I use this for fresh air intake? While optimized for HVAC zoning, its spring return design allows it to be used in various ventilation applications where a normally-open state is required.
