Honeywell ZD14X8TZ Damper

The Honeywell ZD14X8TZ is a 14" x 8" rectangular parallel blade zone damper engineered for precision airflow management in 24Vac residential and light commercial HVAC systems. This power closed spring return open (PC/SO) assembly is designed as a direct replacement for the AOBD-14X8, utilizing a synchronous motor mounted on the 8" side to provide high-torque, fail-safe operation. Built with a heavy-duty extruded aluminum frame and blades, the ZD14X8TZ features a parallel blade configuration for superior low-leakage performance, maintaining less than 1% leakage at 0.5 inches WC.

For contractors, the TrueZONE damper simplifies the installation process with its 2-wire push-terminal block (M1/M6) and an optional M4 terminal for LED position indication. The unit includes adjustable range stops to fine-tune minimum and maximum airflow, ensuring the system remains balanced even during bypass scenarios. The redesigned all-metal drive train and Kevlar gearing provide long-term durability against high static pressures up to 1.0 inch WC. Note that this model is a fail-safe components and must have a panel system for logic control. Its multi-poise mounting allows for installation in any orientation, making it a versatile Honeywell ZD series replacement for existing zone control setups.

• High-Torque Performance: Features a 24V synchronous motor providing 71 in-oz of torque for reliable 90-degree rotation.
• Fail-Safe Logic: Spring return ensures the damper defaults to the open position during power loss, preventing static pressure spikes.
• Durable Construction: Extruded aluminum blades and Kevlar-reinforced gears resist atmospheric corrosion and wear.
• Contractor Friendly: Mechanical visual position indicator and LED diagnostics allow for rapid troubleshooting at the unit.
• Quiet Operation: Parallel blade design and precision motor timing (30 seconds power / 10 seconds spring) minimize audible transitions.

• Is this damper compatible with my current zone board? The Honeywell ZD14X8TZ is optimized for TrueZONE panels but remains compatible with most 24V electronic zoning systems using standard M1 and M6 terminals.
• Can I use this for a fresh air intake? No, because this is a power closed spring open model, it is not recommended for fresh air applications where a normally closed fail-safe is required.
• How do I adjust the minimum airflow? Use the integrated mechanical range stops on the motor assembly to set the maximum closed position, allowing for a bleed air bypass if the system lack a dedicated bypass damper.
