SC8207 Series
FAN REMOTE CONTROL DECODER USED TOGETHER WITH SC5104
DESCRIPTION
SC8207 is a high performance electronic fan controller LSI, Speed
control, off-timer, nature wind, sleep mode are all built into a single chip.
Light control, buzzer output, key control input, as well as remote control
decoding circuitry are all provided to build a full function electronic fan
with remote control capability having the highest performance with the
least external components. Pin assignment and application circuit are
optimized for easy PCB layout and cost saving for electronic fan
application.
SC8207 adopted SDIP-22 or DIP-20 package.

FUNCTION DESCRIPTIONS
SC8207 is an electronic fan control IC, it use electronic touch switch and timer replace the traditional switch
and timer. SC8207 improved nature wind and sleep wind mode except hold the traditional fan functions, and
improved two groups of swing control and light control function. SC8206 cooperate with 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 … … .go along with cycle.
“ON/OFF” key (extension K)
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.
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 and sleep
mode will not be stored).
“SPEED” key (extension K)
SPEED key is used to turn on the fan change speed of the fan. When successive pressing of SPEED key, fan
will operate as follows: low wind, middle wind, strong wind, low wind… … go along with cycle.
“MODE” key:
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 time passes.
b)
c)
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 nature wind.
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.
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.
If fan set in low nature wind at first, it operates in low nature wind, until the preset time end or turn
off.
2)
3)

“TIMER” key:
This key used to set the preset off time.
Type mark with “ mean have four section time output (0.5, 1, 2, 4hour) accumulated.
A4”
Type mark with “ means have three section time output (1, 2, 4 hour) non-accumulated.
N3”
When fan is in the time mode, LED will indicate the remain time, means the fan will stop after the display time.
“LEVEL SWING” key:
If pressed when fan is in the operate mode, it can control the fan swing, it is invalid when fan stopped.
“VERTICAL SWING” key:
N3: If pressed when fan is in the operate mode, it can control the fan vertical swing, it is invalid when fan
stopped.
A4: If pressed when fan is in the operate mode, it can control the fan vertical swing. If continue pressed, fan up
to down swing. When release the key, swing stopped.
“COLD WIND” key:
If pressed when fan is in the operate mode, it can control the fan cold-wind switch, it is invalid when fan
stopped.
“LIGHT” key:
It is used to control light, is independent of the operate mode.
Buzzer output:
a) Turn on send out “
Bi-Bi”
b) Turn off send out “
Bi-“
c) Other available operate (include key press and remote controller receive) send out “
Bi”
