  • Page 4: Features

    FEATURES The TC5-2V4SA is an electronic device used for environmental control in livestock buildings. It allows the user to maintain a specified target tem- perature by controlling the operation of ventilation and heating equipment. Two stages of variable speed fans can be connected to the controller, as well as two stages of constant-speed fans and two stages of either con- stant-speed fans or heating units.
  • Page 5 CONTROL OF AIR INLET MOVEMENT If the TC5-2V4SA is used in combination with a PF-5B controller, the move- ment of the air inlets can be coordinated with the operation of the fans using a potentiometer located on the panel drive.
