Auto Amplifier

System Component Layout - Auto A/C:

AUTOMATIC AMPLIFIER (Auto Amp.)
The auto amp. contains a microcomputer and controls component parts and computes each signal required to operate the auto air conditioner system. This amp. also has a self-diagnosing function to check each sensor and Potentio Balance Resistor (PBR) using indicator lamps.

The auto amp. is unitized with the control panel. The signals from each switch and Potentio Temperature Control (PTC) are, therefore, directly entered into auto amp.
