Resideo ZD20X12TZ Damper
The Resideo ZD20X12TZ (also identified as ZD20X12TZ/U) is a heavy-duty 20x12 rectangular zone damper engineered for tight airflow management in forced-air systems. This parallel blade zone damper utilizes a 24Vac synchronous motor mounted on the 12-inch side, delivering high torque for reliable operation. Designed as a power closed spring return open assembly, it ensures the duct remains open during power loss or system standby, maintaining critical ventilation. Built with a robust galvanized steel frame and synthetic blade bushings, the ZD20X12TZ handles high-velocity residential and light commercial static pressures without blade chatter. This two-position damper is fully compatible with Honeywell TrueZONE panels and other 24V HVAC zoning systems, allowing technicians to achieve precise thermal balancing across multiple zones. Its 2-wire installation simplifies field wiring for faster commissioning on the job site.
Technical Benefits for Contractors
- Fail-safe operation: The spring return open configuration ensures airflow is not restricted during power failures.
- Universal Compatibility: Seamlessly integrates with Honeywell Home and Resideo zoning control panels using standard 24V wiring.
- Durable Construction: Parallel blades provide a tight seal to minimize damper leakage and improve system static pressure control.
- Simplified Installation: The motor is conveniently mounted on the 12-inch side, ideal for tight plenum or trunk duct clearances.
Common Questions
Is the motor replaceable if it fails in the field?
Yes, the synchronous motor on the ZD20X12TZ can be serviced or replaced without removing the entire damper frame from the ductwork.
Can this damper be used with a 3-wire zone control panel?
This is a 2-wire power close spring open model. To use it with 3-wire systems (Power Open/Power Close), verify your zoning panel supports 2-wire spring return outputs or use a relay to convert the signal.
What is the difference between ZD20X12TZ and ZD20X12TZ/U?
There is no functional difference; the "/U" suffix simply denotes the retail/universal packaging. The specifications and physical dimensions are identical.
