Resideo ARD8TZ Damper

Upgrade your zoning efficiency with the Resideo ARD8TZ Damper, a heavy-duty 8-inch automatic round damper designed for seamless integration into TrueZONE systems. This 24Vac motorized damper features a power closed/spring return open configuration, providing a fail-safe position that maintains airflow during power loss. Engineered with 24-gauge galvanized steel and a specialized gasket, it ensures minimal air bypass and meets strict energy efficiency requirements. As a direct replacement for CRDS08 and RSD-8 models, the ARD8TZ simplifies retrofits with a multi-poise actuator that includes integrated adjustable range stops for precision bypass air control. Its two-wire push-terminal design expedites installation, while the optional third-wire (M4) provides a visual LED status for real-time monitoring. Built for high-static environments up to 1 in. wc, this zoning damper offers the rugged reliability professional contractors demand for residential and light commercial HVAC applications.

Key Benefits

• Simplified Installation: Standard 2-wire setup (M1, M6) with push-in terminals requires no specialized tools and matches TrueZONE panel logic.
• Fail-Safe Design: The spring return open actuator ensures air continues to circulate to critical zones if control power is interrupted.
• Precision Airflow: Built-in adjustable range stops allow technicians to bleed bypass air easily, reducing system static pressure and noise.
• High Compatibility: Serves as a drop-in ARD8TZ replacement for legacy Honeywell/Resideo units including the RSD-8 and CRDS08.
• Enhanced Durability: Features an all-metal drive train and 22-gauge blade construction for consistent performance in unconditioned spaces.

Common Questions

Can the ARD8TZ be used for fresh air intake?
Yes, while typically used for zoning, the ARD8TZ is field-convertible for applications requiring a normally open fresh air damper.

What is the purpose of the third terminal (M4)?
The M4 terminal is an optional connection used specifically to power a green LED light to indicate when the damper is in the open position.

Does this damper support flexible ductwork?
Absolutely. The ARD8TZ includes a taping flange and crimped/uncrimped ends to facilitate a secure, airtight seal for both rigid and flexible round ducting.
