In unconditioned spaces, mount the actuator on the side or top of the damper to avoid condensation dripping into the unit. Always follow manufacturer guidelines to prepare the components for a secure and efficient setup.
Mounting the Actuator on the Damper Shaft
Place the actuator over the damper shaft, ensuring proper alignment. Hold the mounting bracket in place and mark the screw holes on the damper housing. Remove the actuator, then drill or center-punch the marked holes. Use self-tapping screws to secure the bracket. Align the actuator’s rotational direction with the damper’s operation. Ensure the actuator is tightly fastened to prevent movement during operation. Double-check the torque requirements and damper sizing for compatibility before finalizing the installation.
Application and Compatibility
Honeywell damper actuators are compatible with ZD, ARD, and EARD series dampers, ensuring precise control of air flow in HVAC systems through accurate torque and sizing matching.
Compatible Damper Models (ZD, ARD, EARD Series)
Honeywell damper actuators are designed to work seamlessly with ZD, ARD, and EARD series dampers, ensuring optimal performance in HVAC systems. The M847D-ZONE model is specifically engineered for use with ARD and ZD dampers, while the M847D-VENT model is tailored for EARD dampers. These actuators are two-position, 24V spring return units, designed to operate directly driven zone or vent dampers. They provide reliable control of air flow in ducts, making them ideal for applications requiring precise modulation; The actuators can be driven open or closed using any 24V rated two-position switch, such as a wall switch or thermostat subbase switch, ensuring versatility and ease of integration into existing systems.
Understanding Torque Requirements and Damper Sizing
Properly sizing the damper and actuator is critical for ensuring reliable operation. Honeywell damper actuators are designed to handle specific torque requirements, which depend on the damper’s size, air flow rates, and system pressure. For example, dampers with larger blade areas or higher air velocities require higher torque actuators. The M847D series actuators are rated for up to 10 sq.ft. (44 lb-in. or 5 Nm) and 20 sq.ft. (88 lb-in. or 10 Nm), ensuring they can manage various load conditions. Refer to Honeywell’s selection guide (Form 63-8038) for detailed sizing charts and torque calculations to match your application needs accurately.
