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
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.
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.
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.
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.

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.
