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’ output, until off 30 second after. The “ t 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.

LED will on/off with key. “TIMER” key: This key used to set the preset off time. Type mark with “ means have four section time output (0.5, 1, 2, 4hours) accumulated. A4” Type mark with “ means have four section time output (0.5, 1, 2, 4hours) non-accumulated. N4” Type mark with “ means have three section time output (1, 2, 4 hours) non-accumulated. N3” Type mark with “ means have four section time output (1, 2, 4, 8 hours) non-accumulated. N8” When fan is in the time mode, LED will indicate the remain time, means the fan will stop after the display time. “SWING1” key: If pressed when fan is in the operate mode, it can control the fan swing, it is invalid when fan stopped. “SWING2” key: (the same as “SWING1” key) If pressed when fan is in the operate mode, it can control the fan swing, it is invalid when fan stopped. “LIGHT” key: It is used to control light, is independent of the operate mode. “ OFF”and “ ON/OFF”key too control light. 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” HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 6 of 9 SC8204 CONTROL PANEL APPLICATION CIRCUIT (Transmitter controller unit) HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 7 of 9 SC8204 TYPECIAL APPLICATION CIRCUIT (Receive control unit) HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 8 of 9 SC8204 PACKAGE OUTLINE SDIP-24-300-2.54 UNIT mm 6.40±0.25 HANDLING MOS DEVICES: Electrostatic charges can exist in many things.
