Each thermo-electric device (TED) contains an internal temperature sensor (thermistor) that is used by the climate controlled seat module (CCSM) to monitor the temperature of each (TED). Based on the temperature of a TED, the internal sensor resistance will vary the voltage on circuit 1548 (DG/LG) (seat cushion TED) and circuit 1549 (DB/OG) (backrest TED).
