The following describes the HVAC control head functionality upon receiving the remote start active serial data message and a power mode status is set to off a wake. Outside ambient temperature sensor, OAT- on automatic systems or intake air temperature (IAT) on manual systems, are utilized to determine the moding of the following features: Blower Mode (Bi-level, floor, Defrost, Recirc and rear Defrost. These features as determined by the OAT/IAT during activation sequence are maintained for the duration of engine run time. Class 2 supplies the ambient temperature. Calibratable temperatures are utilized to provide low, mid and high temperature ranges for feature selectable. Blower and mode have the range to select any valid feature positions. When the remote start active serial data is received ignition-off loop HVAC algorithms will act the same as if a run power mode received (i.e. re-calibration, After blow, ignition-off motor positioning etc.) off timer and ignition on timer have the functionality as in Run mode.
