Resideo zd6x14tz/u Parallel Blade Damper 6x14 in 24V

Product Description

The RESIDEO zd6x14tz/u is a 6-inch by 14-inch rectangular parallel blade damper designed for zone air control in ducted HVAC systems. It operates as a normally-open damper, using a 24-volt motor to power-close and a spring mechanism to return the blade to the open position on loss of power. The motor cycles on a 30-second power-open timing and a 10-second spring-return cycle. Licensed HVAC technicians install this damper in zoned residential and light-commercial duct systems where individual zone control of conditioned air is required.

The zd6x14tz/u fits rectangular duct branches and trunk takeoffs measuring 6 inches by 14 inches. It is specifically noted for use with Honeywell zoning systems, including the TrueZONE product line, and other compatible electronic zoning controllers. The bottom-mounted actuator orientation suits standard horizontal and vertical duct installations where access to the motor is required from below the duct. Terminal connections at M1 for power, M6 for common, and the optional M4 terminal for LED status indication allow straightforward wiring into zone panel boards.

Key Features

• Normally-open design: spring return opens blade on power loss, providing fail-safe airflow
• 24-volt motor compatible with standard low-voltage zoning panel outputs
• 30-second power-open and 10-second spring-return motor timing
• Parallel blade action for uniform airflow control across the 6-inch by 14-inch opening
• Bottom-mounted motor with simplified range stops for quick field adjustment
• Optional M4 terminal supports LED indication for visual zone status confirmation

Compatibility

Designed for use with Honeywell zoning systems, including the TrueZONE line and other compatible electronic zoning controllers that supply 24-volt control signals to zone damper actuators.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage duct zoning systems. De-energize the zone panel and system air handler before making any wiring connections at the M1, M6, and optional M4 terminals. Confirm duct opening dimensions match 6 inches by 14 inches before securing the damper frame to avoid air bypass around the blade. Follow local mechanical codes and the zoning controller manufacturer wiring diagram for proper terminal assignments.
