Resideo zd8x26tz/u Parallel Zone Damper 8x26 in 2 Position 24V

Product Description

The RESIDEO zd8x26tz/u is a parallel zone damper designed for use in residential and light commercial HVAC zoning systems. Operating on 24 volts, this two-position damper opens and closes to direct conditioned air to individual zones, giving the system precise airflow control. It is sized at 8 inches by 26 inches, making it suitable for rectangular duct runs where multi-zone distribution is required. HVAC technicians install this damper as part of a complete zone control setup alongside a zone control panel and individual zone thermostats.

This damper is used in forced-air zoning applications where a single air handler or furnace serves multiple zones. The parallel blade configuration and two-position spring-return operation ensure the damper returns to its default position on power loss, a critical behavior for system safety and comfort. It fits rectangular duct systems and is typically installed during new construction or retrofit zoning projects in residential and light commercial settings.

Key Features

• Two-position operation opens and closes for straightforward zone control
• Spring-return actuator returns damper to default position on power loss
• 24-volt control signal compatible with standard zone control panels
• Parallel blade design for rectangular duct installation
• 8 x 26 inch duct size fits common residential and commercial trunk runs

Compatibility

Designed as an OEM-style replacement or new-installation parallel zone damper for 24-volt HVAC zoning systems using rectangular duct configurations.

Installation Notes

Zone dampers are installed by licensed HVAC technicians as part of a zoning system. Power down the air handler and zone control panel before making any wiring connections. Follow NEC guidelines for low-voltage wiring and refer to the zone control panel manufacturer instructions for damper wiring terminals. Verify the damper blade moves freely and seals properly before restoring system power.
