CONTROL SPECIFICATION
Control item
Required
Required temperature determined by the set temperature and the
discharge
inputted sensor value.
temperature
Auto control
Required discharge temperature is determined by the set temperature
and the inputted sensor value. The feature will use the required
discharge temperature to perform the auto control of temp. actuator,
mode actuator, intake actuator, blower motor and compressor, and
maintain the set temperature stably.
IN-CAR
Upon detecting rapid changes of temperature from the INCAR sensor, it
temperature
will gradually correct the incar temperature value.
correction
AMB
Upon detecting rapid changes of temperature from the AMB sensor, it
temperature
will gradually correct the ambient temperature value.
correction
Photo correction Upon detecting rapid changes of photo intensity from the PHOTO
sensor, it will gradually correct the photo intensity value.
TEMP door
It does the automatic control to maintain the optimum TEMP door
control
opening (0%-100%).It will be computed by the temperature set and the
input signal from each sensor.
Blower speed
Automatic control of the blower speed. The target value will be
computed by the set temperature and the input signal from each sensor.
(7 levels may be selected in case of manual selection.)
Electro-motive
During auto control, it will raise the permitted voltage of blower motor
mode control
gradually in order to improve comfortability.
Photo
During auto control, it will compensate the blower level and the
compensation
discharge temperature according to the photo intensity detected from
the PHOTO sensor at VENT or B/L mode. PHOTO compensation will
begin after 5 seconds when ignition on.
Mode door
Automatic control of air discharge based on the required discharge
