Interior Room Temperature Control System

INTERIOR ROOM TEMPERATURE CONTROL SYSTEM





Control Functions

(a) The desired temperature is set using the TEMP switch.

(b) From the input signals (room temperature sensor, ambient temperature sensor, evaporator temperature sensor and solar sensor) and the temperature setting, the air conditioner control ECU determines the air flow volume and outputs signals to the air mix servomotor.

(c) When it receives signals from the ECU, the air mix servomotor opens or closes the air mix damper to change the air flow temperature. When the temperature reaches the specified temperature, it is detected by the air mix damper position sensor and the ECU stops the servomotor.

HINT: If the desired temperature setting is 65°F, the ECU forcedly sets the air mix damper to the Max Cool position. If it is set at 85°F, the ECU forcedly sets the air mix damper to the Max Hot position.
