  • Page 4: Features

    TC4-2N6F is an electronic device used for environmental control in livestock buildings. It allows the user to maintain a specified target temperature by controlling the operation of ventilation and heating equipment. Two stages of variable speed fans, two stages of constant speed fans, as well as curtains, foggers and heaters can be connected to the controller.
