Hello,

I just noticed that in the Simulink example “Simulating Automatic Climate Control System” there seems to be an issue with the thermodynamic model. For instance, if I set the User Setpoint temperature to 25 °C and the external temperature to –20 °C, the heater does not turn on, which clearly indicates a problem.

Hi @Tommaso

The reason the heater does not turn on is that the thermometer clearly indicates the initial air temperature in the car is 25.5°C, which exceeds the user setpoint of 25.0°C. I believe that if the temperature drops below 25.0°C, the heater will activate.
