Resideo ZD20X14TZ Damper

The Resideo ZD20X14TZ Damper is a professional-grade rectangular parallel blade zone damper designed specifically for heavy-duty forced-air zoning systems. Built with a robust extruded aluminum frame and parallel blades, this unit is engineered for low leakage performance, maintaining less than 1% leakage at 0.5 in. WC. This 20" wide by 14" high HVAC zone damper features a 24Vac synchronous motor mounted on the 14" side, operating as a power closed/spring return open (normally open) component. This fail-safe configuration ensures maximum airflow in the event of power loss. The TrueZONE compatible actuator delivers 71 in-oz of torque and features a redesign of all metal drive train gears with Kevlar reinforcement for extended service life in high-static environments. Contractors can easily integrate this unit using a two-wire installation (M1 and M6 terminals), with an optional third wire (M4) for LED status indication of the open position. Integrated adjustable range stops allow for precise airflow modulation, making it a reliable choice for Honeywell Home zoning applications.

• Aluminum Construction: The extruded aluminum blades and frame offer corrosion resistance and reliable operation in high-temperature environments up to 140°F.
• Fail-Safe Logic: Operates as a normally open zone damper, utilizing a 10-second spring return mechanism to restore airflow upon de-energization.
• Contractor-Friendly Wiring: Simplified 24 volt HVAC damper setup with push terminals and a front-facing display with mechanical visual position indicator.
• Precision Control: Features parallel blade action for consistent air distribution and manageable static pressure drop across the zoning system.

• How do I adjust the minimum airflow? Use the adjustable range stops on the actuator to set a minimum blade position, preventing the zone from closing completely if some continuous flow is required.
• Can this be mounted in any orientation? Yes, the ZD series damper is designed for multi-poise installation, allowing the mounting side to be positioned on either the bottom or the side of the ductwork.
• What are the timing specs for the actuator? The motor typically requires 30 seconds to drive the damper power closed and approximately 10 seconds for the spring return open cycle.
