Resideo ZD8X20TZ Damper
The Resideo ZD8X20TZ is a heavy-duty, rectangular zone damper specifically engineered for professional HVAC zoning applications. Measuring 8 inches wide by 20 inches high, this parallel blade damper is constructed with an extruded aluminum frame and blades to ensure long-term structural integrity in high-velocity systems. It features a high-torque 24VAC synchronous motor mounted on the 20-inch side, providing a power closed spring return open configuration. Use this normally open damper in systems where a fail-safe open position is required for emergency ventilation or to prevent coil freeze-ups. The motor utilizes a simple two-wire installation (M1 and M6) with an optional third terminal (M4) for LED status indication, making it highly compatible with TrueZONE panels and other standard 24-volt zoning systems. Built for efficiency, the blades include synthetic gaskets that minimize air bypass, maintaining static pressure ratings up to 1.0 in. wc.
Key Benefits- Fail-Safe Operation: The spring return mechanism automatically drives the blades to the full open position upon power loss, preventing airflow restriction.
- Enhanced Sealing: Features a parallel blade design with synthetic rubber gaskets to achieve less than 1% leakage at 0.5 in. wc.
- Contractor-Grade Construction: Built with non-corrosive extruded aluminum and synthetic bearings for smooth, quiet operation in demanding environments.
- Direct Panel Integration: Simplified 24V wiring allows for rapid integration with most residential and light commercial zone control boards.
- Visual Monitoring: Built-in mechanical position indicator allows techs to verify damper status at a glance without removing ductwork.
How do I wire the ZD8X20TZ to a zone panel?
Connect 24VAC to terminals M1 (Power) and M6 (Common). Since this is a power closed model, the motor will energize to close the damper and use the internal spring to open when the zone calls for air.
Where should the motor be positioned during installation?
The motor for this model is factory-mounted on the 20-inch side. It can be installed in any orientation—bottom or side—as long as there is three feet of clearance from the HVAC plenum for proper airflow stabilization.
Can I adjust the range of the damper blades?
Yes, the motor includes adjustable range stops, allowing you to limit the travel of the blades if a minimum bleed of air is required for the zone when "closed."
