SC8204
FUNCTION DESCRIPTION
SC8204 is an electronic fan control IC, it use electronic touch switch and timer replace the traditional switch
and timer. SC8204 improved nature wind and sleep wind mode expect hold the traditional fan functions, and
improved a swing control and light control function. SC8204 cooperate with the SC5104 encode IC; implement
the remote control of the fan.
“OFF” key
It used to shut down the power of motor, fan stop operating, and the control circuit resume static state, and
stored the operate mode of power on. When started next time, it is activated into the operation mode stored in
the operation memory. (Timer will not be stored)
“ON/SPEED” key:
It start fan if pressed when fan is off.
Mode one: It turns on the fan with cold wind start-up. If successive pressing of ON/SPEED key, it will operate
as low wind, strong wind, cold wind, low wind, strong wind … … go along with cycle. Or the operation mode
stored in the operating memory. LED will on/off with key.
Mode two: It turns on the fan with low wind start-up .If successive pressing of ON/SPEED key, it will operate as
strong wind, low wind, strong wind … … go along with cycle. LED will on/off with key.
Separating “ON/OFF” key (extension K)
It start fan if pressed when fan is off.
Mode one: It turns on the fan with cold wind start-up. Cold wind LED will on.
Mode two: It turns on the fan with low wind start-up .Low wind LED will on.
It turn off the power when fan is on, fan stopped, control circuit resume static state, and stored the operate
mode into memory. When the fan turn on next time, it start in the operate mode in the memory (timer will not be
stored).
Separating “SPEED” key (extension K)
SPEED key is used to turn on the fan change speed of the fan.
Mode one: When successive pressing of SPEED key, it will operate as low wind, strong wind, cold wind, low
wind, strong wind … … go along with cycle. LED will on/off with key.
Mode two: When successive pressing of SPEED key, it will operate as low wind, strong wind, low wind, strong
wind … … go along with cycle. LED will on/off with key.
“WORKING MODE” select pin (extension F)
(Note˖The consumer may connect Vss or disconnect anything to select working mode in PCB.)
It used to select the working mode. Two working mode selectable.
Working mode one (SELECT pin connect to Vss): press “ON/OFF”key or “ON/SPEED”, Buzzer output
“Bi-Bi”, pin”FAN”output to control cold assistant part, and always output. (Cold wind LED will on.)The “FAN”
hasn’t output, until off 30 second after. The “FAN”output has nothing to do with fan working. Follow successive
pressing of “SPEED”or “ON/SPEED”key, it will operate as low wind, strong wind, cold wind, low wind, strong
wind… … go along with cycle. LED will on/off with key.
