Correction of Setpoint Values

Outside temperature input: The setpoint value is corrected as a function of the outside temperature. The effects of radiation from outside and surrounding surfaces of the passengers are thus compensated. The outside temperature is recorded in the fender areas by an external temperature sensor and transmitted via the K-CAN bus to the IHKA. The outside temperature input and thus specified value increase can be between +12°C and -2°C. The outdoor temperature input also serves as so-called pre-activation for a possible disturbance variable.

Interior temperature sensor: The control panel accommodates a temperature sensor with inside sensor fan for recording the interior temperature.
