FUNCTIONAL DESCRIPTION
1. CONTROL KEYS
Up to six(6) function keys – SPEED, MODE, TIMER, SW1, LIGHT and OFF/MEMS – may be used on the
control panel of fan to access SC2128C to its full versatility. OFF/BUZZ key input pin serves further as buzzer
output BUZZ pin. All key inputs are internally pulled-high in SC2128C.
SPEED key controls the fan speed. TIMER key adjusts off-timer. MODE key sets fan into various modes of
operation. SW1 key control the head swing of fan. LIGHT key toggles the LIT output ON and OFF. OFF/BUZZ key
resets the fan to idle state when fan is ON. LIT output is not affected by OFF key.
