FUNCTION DERCRIPTION

SC8206 is an electronic fan control IC, it use electronic touch switch and timer replace the traditional switch and

timer. SC8206 improved nature wind and sleep wind mode expect hold the traditional fan functions, and improved a

swing control and light control function. SC8206 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 and sleep wind mode will not be stored)

“ON/SPEED” key:

It start fan if pressed when fan is off. It turn on the fan with middle wind for increase start moment. After three

second, it resume low wind mode, or the operation mode stored in the operating memory.

This key set the operate mode when fan is on, if successive pressing of ON/SPEED key, it will operate as low wind,

middle wind, strong wind, low wind, middle wind

ffgo along with cycle.
