>I created an automated system controlled by a temperature dial. This, in turn, determines the fan speed and seat heating. If the cabin temperature deviates significantly from the set temperature, the system will increase the fan speed and seat heating or cooling accordingly.

Oh, god. It just keeps getting worse. I don't want a fake knob that simulates a real one except it ignores me and decides the fan speed, blend door position, and probably the recirculation door on its own (allowing only a temporary override). I want a fan dial that is electrically connected to the fan, such that the position of the dial directly controls the voltage being sent into the fan motor, with no computer or robotics in between. In other words, a step switch. And I want a slider that is mechanically connected to the blend door for controlling temperature, again, with no computer or robotics in between. And the same for the recirculation door.
