Temperature Mix Flap

Temperature Mix Flap

The temperature mix flap is presented here as an example of flap control based on the main state variables and also serves to illustrate how all the other flaps function.

Cooling mode applies below state variable ERL < 85 - The command variable for the mix flap position is directly dependent on the result of the flap position calculation (check back from potentiometer of the drive motor).

Heating mode applies above ERL 150 - In this case, the position of the mix flap is determined solely by a subordinate footwell air outlet vent temperature sensor.

At ERL > 85, the mix flap control system is overridden by the initiated footwell air outlet vent temperature sensor.
