AIR CONDITIONING SYSTEM - Plasmacluster Circuit


DESCRIPTION

The plasmacluster operates in conjunction with blower switch operation. The plasmacluster operation indicator (CLEAN, ION) illuminates on the A/C control assembly when the plasmacluster is operating. When the plasmacluster is operating, the operation mode automatically switches between the sterilization mode (CLEAN) and the negative ion mode (ION) every 15 minutes.
