Greenheck 385803 Control
The Greenheck 385803 VariGreen Remote Dial with Min/Max Setting is a critical interface for managing EC motor control systems in commercial ventilation applications. This field-mounted potentiometer allows for precise manual motor speed adjustment, enabling contractors to balance airflow without accessing the fan housing. It is specifically designed for Greenheck VariGreen motors and controllers that require a 0-10VDC signal for operation. The integrated Min/Max limit setpoints allow for the calibration of minimum and maximum operating frequencies, ensuring the system stays within design airflow parameters and preventing motor stalling or over-ramping. Built for reliable performance in demanding environments, this VariGreen remote dial control facilitates easier HVAC system commissioning and long-term maintenance. By providing a localized point of adjustment, it streamlines the process of meeting variable air volume (VAV) requirements and optimizing overall fan performance efficiency.
Key Benefits- Precise 0-10VDC Output: Ensures seamless communication with VariGreen EC motors for linear speed modulation.
- Adjustable Min/Max Setpoints: Restricts the control range to job-specific airflow requirements, protecting equipment from improper operation.
- Remote Field Mounting: Allows for convenient motor speed monitoring and adjustment away from the fan unit.
- Simplified System Balancing: Reduces labor time during the air balancing phase of a project.
- Durable Construction: Engineered to withstand the rigors of commercial mechanical rooms.
How do I wire the Greenheck 385803 to an EC motor?
The control typical uses a three-wire configuration, deriving a 24VDC or 10VDC supply from the motor's onboard power source and returning a 0-10V control signal based on the dial position.
Can this dial be used to set a minimum ventilation rate?
Yes, the internal Min/Max trim pots allow you to define a floor and ceiling for the speed range, ensuring minimum ASHRAE ventilation standards are maintained regardless of the dial position.
Is the Greenheck 385803 compatible with third-party VFDs?
While designed for the VariGreen ecosystem, it can function with any drive or controller accepting a standard 10VDC analog input, provided the power supply requirements are met.
