    Vari-Green VOC Control

    $1,694.56

    The Indoor Air Quality VOC control senses the level of volatile organic compounds (VOCs) in a space and automatically adjusts the ventilation rate to the space by increasing or decreasing the speed of the fan based on the level of VOCs present. Up to 10,000 unique VOCs exist and Greenheck's VOC sensor can detect all of them. Recommended for applications experiencing intermittent human traffic including bathrooms, classrooms, cafeterias, or other spaces where quality of air is a concern.

    • Adjustments for air quality setpoint, minimum and maximum fan speed
    • Fan speed and VOC level are available as analog outputs to be read by a building automation system or secondary device.

    Vari-Green Temperature/Humidity Control

    $560.82

    The Indoor Air Quality Temperature / Humidity control monitors the temperature and/or the relative humidity in a space. It will automatically adjust the ventilation rate to or from a space by increasing or decreasing the speed of the fan based on the desired set point. Recommended for use in assisted living facilities, schools, prisons and buildings constructed of materials that are more sensitive to high moisture levels.

    • Adjustments for set point, minimum and maximum fan speed
    • Fan speed and temperature or humidity level are available as an analog output to read by a building automation system or secondary device.

    Vari-Green 2-Speed Control, with Digital Inputs

    $106.89

    The two-speed control allows motor RPM (fan speed) to operate between two discreet speeds (A or B) through an SPDT switch or relay connected to the dry contact input or through wet voltage (115-230VAC) applied to the digital input terminal. This control accepts an input voltage of 115/208-240V and is intended for use with Greenheck's Vari-Green motor. Recommended for use in schools, restaurants, multi-family structures and condos where manual or demand controlled ventilation applications requiring high and low speed operation exist.

    • Accepts input voltage of 85-277VAC
    • Intended for use with Greenheck's Vari-Green motor and Vari-Green Drive

    Vari-Green Touch Remote Control

    $71.26

    The Vari-Green remote dial control allows the user to manually adjust the fan's speed from a remote location. This control includes a countdown timer to automatically turn the fan off after 10, 30, 60 or 90 minutes. Recommended for use in commercial buildings and restaurants.

    • Mounts to a single or multi-gang junction box
    • Includes lockout feature to prevent tampering.

    Vari-Green Remote Dial Control, with Min/Max Setting

    $46.32

    The Vari-Green remote dial control allows the user to manually adjust the fan's speed from a remote location. This control mounts to a wall using a 2x4 junction box and is supplied with a wall cover plate. Recommended for use in commercial buildings and restaurants.

    Vari-Green Control, Transformer Kit, 85-277VAC-24VDC W/ Aux

    $274.35

    The Vari-Green transformer provides a 24-volt power source from the existing line voltage at the fan to the motor and controls. It has two dry auxiliary contacts (one normally open and one normally closed) available to signal a motorized damper or interlock with other devices.

    Vari-Green Constant Pressure Control, Integral Transducer with Duct Probe

    $1,077.45

    The Constant Pressure Control can be used to monitor static pressure in a system, automatically adjusting the fan speed to maintain a desired static pressure. This control reduces energy consumption not only by reducing the speed and the energy used by the fan, but will also reduce the amount of conditioned air that is exhausted. Recommended for use in multi-family structures, hotels and schools where demand control ventilation applications exist.

    • 2-line, backlit display
    • Dedicated airflow control mode
    • Integral pressure transducer maintains compact form
    • NEMA-4 enclosure on all components
    • Pressure range of +/- 1.0 inch wg
    • Intended for use with Greenheck's Vari-Green motor and Vari-Green Drive
