Three conditions may occur: Your comprehension is correct, I test it just now on your suggestion: If I set pwm2_enable into thermal cruise mode first, then set the thermal_cruise2 into a low value such as 25(degree), the pwm2 will decrease automatically step by step. On the other hand, if I set the thermal_cruise2 into a large value such as 42(degree) under thermal cruise mode, the pwm2 will increase step by step, If the set thermal_cruise2 is very larger such as 80(degree), the increase of pwm2 may be very quickly, for example, from 9 into 15(full) in ONE step.
