Resideo by HoneyWell 24V Automatic Round Damper Normally Open

The Resideo by Honeywell 24V Automatic Round Damper is a normally open zone damper for forced-air heating, cooling and ventilation systems. Some people call it an automatic zone damper or a TrueZONE round damper. It uses a 24-volt, spring-return actuator. The actuator drives the blade closed when powered. When power is removed, the spring returns the blade to the open position. This lets you control airflow zone by zone.

Key Features:

• 24V actuator with power-close, spring-open operation
• Fail-safe, normally open design, so the damper returns to open when power is removed
• Galvanized steel, single-blade construction
• Blade closes tightly against a gasket to keep leakage low
• Adjustable range stops for setting the closed position
• Male (crimped) and female (uncrimped) ends connect to rigid or flexible round duct
• Simple two-wire installation, with an optional third wire for an open-position LED indicator
• Rated to operate up to 1 in. wc
• Designed for use with Honeywell zoning systems

The single-blade design runs quietly and is built to last. It is a dependable choice for residential zoned HVAC systems. It can also be field-converted for use as an independent zone or for fresh air intake.
