Resideo M847D-ZONE Replacement motor

The Resideo M847D-ZONE replacement motor is a purpose-built 24Vac spring return actuator engineered for direct compatibility with ARD and ZD zone dampers. This two-position damper motor provides reliable air flow control in residential and commercial zoning systems. Designed as a direct replacement for M847D1004, the unit features a power closed, spring open configuration, ensuring the damper default position is open during power loss for system safety. With a 30-second power-closed cycle and a rapid 10-second spring return, it delivers high-performance mechanical response. The motor includes adjustable range stops for precise blade positioning and is equipped with 7/16-inch drive shaft extensions for direct mounting to coupling-style dampers. Techs typically wire this to M1 (Power) and M6 (Common) terminals, with an optional M4 terminal for LED status indication. This low voltage actuator is the industry standard for maintaining Honeywell and Resideo zoning infrastructure without requiring full damper assembly replacement.

• Direct OEM Compatibility: Serves as a 1:1 drop-in replacement for M847D1004 on existing ARD and ZD dampers.
• Fail-Safe Design: The spring return mechanism ensures dampers fail to the open position to prevent static pressure spikes.
• Simplified Calibration: Features adjustable minimum and maximum range stops to tailor airflow volume per zone.
• Streamlined Installation: Built-in anti-rotation pin and drive shaft extensions eliminate the need for additional mounting hardware in standard applications.

• Is this compatible with EARD ventilation dampers? No, the M847D-ZONE is intended for power-closed/spring-open applications; use the M847D-VENT for ventilation dampers that require power-open operation.
• What are the wiring requirements for this motor? This unit requires secondary 24V power. Standard wiring utilizes terminals M1 and M6, while M4 is reserved for optional LED indication.
• Can I adjust the damper travel distance? Yes, the simplified range stops allow technicians to set exact limits to balance air distribution across different zones effectively.
