COMPONENT DESCRIPTION
Unified Meter and A/C Amp. (Automatic Amplifier)
The unified meter and A/C amp. has a built-in microcomputer which processes information sent from various sensors needed for air conditioner operation. The air mix door motor, mode door motor, intake door motor, blower motor and compressor are then controlled.
When the various switches and temperature control switch are operated, data is input to the unified meter and A/C amp. from the display control unit using CAN communication.
Self-diagnosis functions are also built into unified meter and A/C amp. to provide quick check of malfunctions in the auto air conditioner system.
Potentio Temperature Control (PTC)
The PTC is built into the A/C and AV switch. It can be set at an interval of 0.5 °C (1.0 °F) in the 18 °C (60 °F) to 32 °C (90 °F) temperature range by pressing temperature control switch. The set temperature is displayed.
