Resideo M847A1080 Actuator

The Resideo M847A1080 Actuator is a reliable two-position draft damper actuator designed for use with residential and light commercial zone dampers or flue dampers. Operating on 24Vac, this spring return actuator provides 1.9 lb-in torque, ensuring consistent performance in demanding draft control applications. The clockwise wheel rotation (when facing the wheel) and a rapid 20-second maximum run time allow for precise airflow management. Engineered for durability, it features a round shaft and includes a 38-inch linkage chain for versatile field installation. With an operating temperature range of 40 to 125 degrees Fahrenheit and a humidity tolerance of 5-95% RH, this unit maintains low voltage control integrity in variable mechanical room environments. Whether you are performing a damper motor replacement or a new system install, the M847A1080 provides the mechanical torque necessary to maintain proper draft pressure and system efficiency.

• Efficient Power Consumption: 24Vac operation integrates seamlessly with standard HVAC control circuits and transformers.
• Fail-Safe Operation: The robust internal return spring ensures the damper returns to its normal position upon power loss.
• Quick Installation: Includes essential 38" linkage for immediate connection to existing barometric or draft dampers.
• Consistent Cycle Timing: The 20-second stroke speed prevents lag in draft correction, optimizing combustion or ventilation cycles.

Common Questions

Is the M847A1080 compatible with other brand dampers?
As long as the damper uses a compatible round shaft or linkage system and requires 1.9 lb-in of torque or less, this Resideo actuator can typically be adapted for various 24V draft control applications.

Which direction does this actuator rotate?
The wheel rotates clockwise when you are facing the wheel side of the unit. Ensure your linkage is configured correctly for this rotation to avoid binding.

Can I use this in high-heat flue applications?
The ambient operating range is capped at 125°F. For flue applications, ensure the actuator is mounted at a distance where the ambient heat does not exceed this rating, utilizing the provided linkage chain to isolate the motor from the heat source.
