Temperature Control
The temperature control is made based on the drivers inputs from the temperature set switch and the data from various temperature sensors; the ECM determines the TAO using these data and operates the air mix motor so that the TAO can be attained.
The ECM compares the air mix damper opening it has received from the air mix damper potentiometer with the target opening it has calculated and, if necessary, operates the motor to move the damper to the HOT or COOL side and hold the damper in an appropriate position.
The target damper opening is corrected using the sunlight intensity data.
The air mix damper is moved fully to the HOT side and held there when the temperature set switch is placed at the FULL HOT position (32°C, 89.6°F), while it is moved fully to the COOL side and held there when the switch is placed at the FULL COOL position (18°C, 64.4°F).
