PURPOSE:To improve the interchangeability of each specification by permitting a controller for determining the opening degree position of an air mix damper to be used in common in the automatic air conditioning specification and in the manual air conditioning specification by changing the resistors for providing the input signals in the controller. CONSTITUTION:The controller 2 for an automatic air conditioner consists of a temperature setting resistor R1 for providing an aimed car-interior temperature, opening-degree position detection resistor Rpo in which the resistance value varies according to the opening degree of an air mix damper, inside air temperature detection resistor Rr in which the resistance value varies according to the representative car-interior temperature, and an outside air temperature detection resistor Ram in which the resistance value varies according to the representative outside temperature. When the automatic air conditioner is changed to the manual specification in this case, the above-described resistors Rr and Ram are demounted, and a resistance Rc for intermediate adjustment for the air mix damper is connected to the resistor Rpo. In order to suppress the variation of the resistance R1, a resistor RX1 is connected in parallel to the resistor R1. Further, a resistor RY1 is connected in seried with the resistor R1, and correction is performed. |
