INDIVIDUAL COMPONENT FUNCTION
  • The conditions that are set for the automatic air conditioning system that is operated by each control switch are transmitted to the A/C amp. via LIN communication.
  • The operating status of the automatic air conditioning is transmitted from the A/C amp. via LIN communication.
 
 
COMPONENT OPERATION
  • The operation status of each switch is detected by the control and is transmitted as an operation signal to the A/C amp. via LIN communication.
  • The following switch specification control was adopted.
    • Temperature control: Dial type
    • Air outlet control: Push-return type
    • Air inlet control: Push-return type
    • Air flow control: Push-return type
    • A/C compressor ON/OFF: Push-return type
      noteRegarding the push switches: Refer to the following for the differences between push-lock types and push-return types.

      Push-lock type
      • Switch ON operation: At the time of switch ON operation, the switch is pushed from the reference point to the pushed position , and the switch turns ON. When the switch is released from this position, the switch returns from the pushed position to the hold position , and the switch position is held there.
      • Switch OFF operation: At the time of the switch OFF operation, the switch is pushed from the hold position to the pushed position . When the switch is released from this position, the switch returns from the pushed position to the reference point , and the switch turns OFF.
      Push-return type
      • Switch ON operation: At the time of the switch ON operation, the switch is pushed from the reference point to the pushed position , and the switch turns ON. When the switch is released from this position, the switch returns from the pushed position to the reference point .
      • Switch OFF operation: At the time of the switch OFF operation, the switch is pushed from the reference point to the pushed position , and the switch turns OFF. When the switch is released from this position, the switch returns from the pushed position to the reference point .
  • For details the function of each switch. Refer to Switch Name and Function.
