Thermal compensation

This function is activated when internal temperature is above thermal threshold (135,145,150, or 160 degrees). In this case, the V setting

fixed by the LIN or by default is compensated to reduce internal temperature. The de-rating is calculated depending on the 4 categories

of V setting.
