Honeywell ZD14X10TZ Damper

The Honeywell ZD14X10TZ is a 14" wide by 10" high parallel blade zone damper designed for standard rectangular ductwork in forced air zoning systems. This heavy-duty 24VAC motorized damper features a power-closed, spring-return-open configuration, ensuring a fail-safe open position during power loss or system failure. Built with a synchronous motor mounted on the 10-inch side, it offers high-torque performance for reliable blade positioning. The ZD14X10TZ serves as the direct internal upgrade and field replacement for the legacy AOBD-14X10. Technicians should note the wiring transition: the ZD series utilizes a simplified 2-wire motor connection, whereas the older AOBD models utilized a 3-wire setup. Constructed with heavy-duty galvanized steel and featuring synthetic blade bushings, this damper minimizes air leakage and ensures quiet operation across multi-zone HVAC installations. It is compatible with most 24V zone control panels that support power-closed/spring-return logic.

• Direct Retrofit Capability: Expertly replaces the AOBD-14X10 with a more efficient 2-wire actuator design.
• Fail-Safe Operation: The spring-return mechanism defaults the blades to the open position to prevent coil freeze-ups or high-limit trips.
• Industrial Build Quality: Parallel blades and a rigid frame design minimize bypass leakage in high-static pressure environments.
• Ease of Installation: The synchronous motor provides consistent timing and simplified wiring for faster commissioning on the job site.

Common HVAC Contractor Questions

Can I use the ZD14X10TZ to replace a 3-wire AOBD damper?
Yes, this is the official replacement for the AOBD-14X10. Since it uses a 2-wire power-close architecture rather than the older 3-wire system, you will need to terminate only the hot and common wires from your zone panel.

On which side is the motor mounted?
The motor is factory-mounted on the 10-inch dimension side, which is critical for clearance planning within the mechanical room or crawlspace.

Does this damper require a specific zone panel?
The Honeywell ZD series is compatible with any 24VAC zone controller capable of providing continuous power to close the damper and removing power to allow the spring-return to open.
