Remote Fan Control Ic SC 5104 and SC 8206
by Silan Semiconductors
Here we will describe about functional IC special purpose for remote Fan
Control. The compact IC no need more electronics component
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.
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)
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 go along with cycle.
It used to select the operating mode. If pressed successively when fan is on, it
will operate as follows: normally
wind, nature wind, sleep wind, normally, nature wind go along with cycle.
A) Ordinary wind: the he wind speed is set by SPEED key and does not change as
B) Nature wind: it is set in program, and operate with “SPEED” key, can produce
strong nature wind, middle nature wind, low nature wind, simulate the really
C) Sleep wind: In sleep wind mode, the wind speed steps down automatically one
level every interval, until it reaches low wind level.
Where is the rule of down:
1 If fan set in strong wind mode at first, it operate in strong nature wind for
half an hour, then switch into middle nature wind, after half an hour switch
into low nature wind, until the preset time end or turn off fan.
2 If fan set in middle wind mode at first, it operates in middle nature wind for
half an hour, then switch into low nature wind, until the preset time end or
turn off fan.
3 If fan set in low nature wind at first, it operates in low nature wind, until
the preset time end or turn off.
This key used to set the preset off time.
Type mark with “A4” mean have four section time output (0.5, 1, 2, 4
Type mark with “N3” means have three section time output ( 1, 2, 4
When fan is in the time mode, LED will indicate the remain time, means the fan
will stop after the display time.
If pressed when fan is in the operate mode, it can control the fan swing, it is
invalid when fan stooped.
