DESCRIPTION
The ion generator sub-assembly operates when both the ion generator switch and the blower switch are on. The air conditioning amplifier assembly sends a drive signal to the ion generator sub-assembly. When the ion generator sub-assembly receives the drive signal and starts to operate, it outputs an operation condition signal to the air conditioning amplifier assembly.
