Climate Controlled Seat System

The seat cushion is equipped with a TED assembly that includes a seat blower (fan motor, serviced as an assembly with the TED). Similarly, the seat backrest is also equipped with its own TED assembly with blower. Cabin air is drawn through the blower and distributed to each TED located in the seat cushion and backrest. The TEDs  heat or cool the air, which is then directed into the foam pad and manifold where it is distributed along the surface of the cushion and backrest of the seat. Once the system is activated, the DCSM uses a set of flexible algorithms to control the heating/cooling modes and the blower speed dependant on the commanded climate controlled seat settings.

The DCSM monitors seat cushion temperature while it supplies voltage and ground to both blower motors. The DCSM also supplies a variable voltage signal to control the blower speed. Cabin air enters the blower through a filter attached to the TED housing. Heated or cooled air exits the TED and flows through a manifold attached to the foam pad.
