Speed controls are used for manual adjustment of the fan’s performance (for final system balancing) or to control the fan’s output in confined spaces, such as conference or meeting rooms. The fan can be adjusted to 60% of design airflow with a speed control. This reduction in airflow and fan speed is also accompanied by a reduction in noise level. Note: For use on direct drive fans with single phase, PSC or shaded pole motors.

Transformers are available for applications requiring voltage reduction. Selection is based on motor amperage. Rated for 115 to 230/277V, 6.5A.

Motion detectors use a passive infrared motion detector to automatically turn the fan on when a change in motion is sensed. They have a viewing area of 180 degrees, however they must be placed in the line-of-sight. May be used with SP and CSP fans or fan/light combinations.

Dehumidistats are available with models SP and CSP fans to ventilate humid spaces. The sensor automatically detects excess humidity and activates a ventilation fan for control of excess condensation. There are automatic, manual, or air cycle modes. This can replace a single pole switch for control of a ventilating fan.

The Constant Airflow Control is used to monitor velocity pressure in a system, automatically adjusting the fan speed to maintain a desired velocity pressure (constant CFM). 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.

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.

Model MS-16 is a 1 Pole, single throw wall mount manual starter with pilot light. This starter supports up to 1/2 HP, 120 Volt, 1 Phase and includes a face plate.

When the temperature in the space rises above the set point of 50 F - 90 F the contacts close and the thermostat will signal the fan to come on in order to exhaust air from the space. Includes face mounted thermometer that displays room temperature.

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.
