  1. The climate controlled seat system is controlled by the climate controlled seat control unit.
  2. Operation of the climate controlled switch sends heated or cooled airflow and adjusts the seat temperature.
  1. One thermal electric device (TED) unit is installed in each seat cushion and seatback. The device heats or cools, sends airflow to the seat surface, and adjusts the seat temperature.
  2. The thermal electric device (TED) is a heat exchanger that has a function to heat or cool the airflow from the climate controlled seat blower motor. (By changing the direction of the current from the power supply, the device takes or gives heat, and adjusts heat exchange process depending on voltage. NOTE: The climate controlled seat blower maintains low speed for approximately 60 seconds after turning the climate controlled seat switch. CAUTION: The thermal electric device has a dual-climate function that allows one side to operate at a high temperature and the other to operate at a low temperature simultaneously. Before starting the work, always turn OFF the switch and check that the thermal electric device is cold.
