REMOTE FAN MCU FUNCTION DESCRIPTION SM3015 has two control types : panel keypad and infrared remote control. There are four to eight control signal operations : * Start-up by SPEED key a. function turn off (OFF key) b. wind mode select (MODE key) c. start-up function and wind speed select (SPEED key) d. timer setting (TIMER key) e. swing head or tuner for swing angle (SW1 and SW2 key) f. lighting control (LIGHT key) * Start-up by ON/OFF key a. function control (ON/OFF key) b. wind mode select (MODE key) c. wind speed select (SPEED key) d. timer setting (TIMER key) e. swing head or tuner for swing angle (SW1 and SW2 key) f. lighting control (LIGHT key) All functions can be planned by user like an MCU for more product application. Only SPEED or ON/OFF key can enable the fan controller, except for the light control. Wind mode, timer and swing head inputs can not be accepted when fan is not activated. The fan controller will be turned off by timer and OFF (ON/OFF) key inputs. When more than one key are pressed, controller will not accept the multi-key's control signal, if the panel keys are pressed more than six seconds, controller will generate a " BI-BI-BI-BI" warning sound. When fan is enabled by SPEED or ON/OFF key, the initial state of fan controller is as follows: * Memory function available If Fan controller is OFF on sleep mode, all memory functions will be returned to the LAST TURN ON STATE. a.Grade as last state but with starting medium wind for three seconds (MASK option) b. The wind mode as last state except sleep mode c. Swing function as last state d. Timer setting off e. Light is independent * Non-memory function (Bonding option) a. Grade is low wind function but with starting medium wind for three seconds (MASK option) b. Normal wind mode operation c. Timer setting and swing head off d. Light is independent Page 5 V.2.0 Mar 8, 2002 三合微科股份有限公司 SM3015 SAMHOP Microelectronics Corp. REMOTE FAN MCU A. OFF KEY When fan controller is on, press the OFF key on panel or remote control handset, fan functions will be turned off except light output. * BONDING OPTION : ON/OFF KEY When fan controller functions are on, press ON/OFF key on panel or remote control handset, fan functions will be turned off; if functions are off, press the key to turn on fan functions. Light output is independent. B. SPEED KEY When fan control is off, press SPEED key on panel or remote control handset, fan is turned on; when memory function is available, the wind grade will operate as last state. Both conditions have three seconds starting wind. Press the SPEED key again, the wind will be changed as follows : OFF LOW MEDIUM STRONG SPEED key used Pulse is put into OFF pin * BONDING OPTION: SPEED KEY ONLY If fan controller is off, SPEED key cannot be used, must press ON/OFF key to turn on the fan controller.

REMOTE FAN MCU * MASK OPTION: WIND GRADE a. There are two types of wind grade control function to choose. If fan controller is on, press SPEED key on panel or remote control handset, wind grade changes as follows: 1. OFF LOW MEDIUM 2. OFF LOW STRONG STRONG SPEED key used SPEED key or ON/OFF key used b. Memory or non-memory function can be chosen. C. MODE KEY SM3015 has four types of wind mode: normal, rhythm, sleep + rhythm, and sleep + normal these can be chosen by mode key setting. Memory function is available except on sleep mode. 1. OFF NOR RHY SLP-RHY : Press MODE key: normal setting : Pulse is put into OFF or ON/OFF pin : SPEED or ON/OFF key used Page 7 V.2.0 Mar 8, 2002 三合微科股份有限公司 SM3015 SAMHOP Microelectronics Corp. REMOTE FAN MCU * MASK OPTION: a. Memory or non-memory function can be chosen. b. There are five kinds of wind mode operation. OFF NOR OFF NOR OFF NOR RHY SLP (RHY) OFF NOR RHY SLP (NOR) OFF NOR RHY SLP (NOR) RHY SLP (RHY) Press MODE key: normal setting Pulse is put into OFF or ON/OFF pin SPEED or ON/OFF key used D. LIGHTING CONTROL KEY The LIGHT key is independent and the output is toggle function. When the LIGHT key is pressed on panel or remote control handset, operation is as follows : OFF Light output key Press LIGHT key * MASK OPTION: Fan controller is off, LIGHT key cannot be used. Page 8 V.2.0 Mar 8, 2002 三合微科股份有限公司 SM3015 SAMHOP Microelectronics Corp. REMOTE FAN MCU E. TIMER KEY SETTING SM3015 has many types of timer adder for three or four steps. Timer key will not activate when fan controller is off. These types of timer may be chosen by bonding option. MODE A: Timer with accumulation Timer Pulse No. Four-steps Type A*1 A*2 A*3 A*4 Three-steps Type A*1 A*2 A*3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 MODE B: Timer with non-accumulation Timer Pulse No. Four-steps Type A B C D Three-steps Type A B C 1 2 3 4 LED display * MASK OPTION: A,B,C,D time base are common multiple by 15 minute ascending, and each number can be set by user. Page 9 V.2.0 Mar 8, 2002 三合微科股份有限公司 SM3015 SAMHOP Microelectronics Corp. REMOTE FAN MCU F. SWING KEY:SWING1 AND SWING2 The swing key will not activate when fan controller is off. Memory function is available, the swing output will operate as last state when press SPEED or ON/OFF key, except tuner function using. A/C Type : SM3015A has two keys of SW1 and SW2 to control the outputs of SHO1 and SHO2 (toggle function). OFF OFF SHO1 enable (Right / Left) The SW1 key pressed SHO2 enable (Up /Down) The SW2 key pressed When SHO1 and SHO2 outputs enable together, the swing head has 3D function. B/D Type : SM3015B/D has only one SWING key to control the outputs of SHO1 and SHO2. OFF SHO1(Right & Left) SHO2(Up & Down) 3D ∞ :The SWING key pressed * MASK OPTION : a. SHO1 and SHO2 output can be enabled when fan controller is off. b. SHO1 and SHO2 output functions can be chosen as a continuous outputs respectively like a micro-swing switch to tune the swing angle.

SLT KEY When fan controller functions are on, pres the sleep mode, then press the SLT key to set the timer of the wind grade down. The time base of SLT key is 0.5HR/1HR/2HR. H. MEMORY FUNCTION Memory of speed, mode(except sleep mode) and swing functions can be set independently. Memory function can be cancelled by Bonding option. When memory function is available, wind speed mode and swing functions will operate as last state; if last state is sleep mode, press SPEED or ON/OFF key enable fan controller while memory functions(Speed/Mode/Swing) will be returned to the last state before sleep mode operation. I. STARTING WIND Memory or non-memory type, fan controller starts with three seconds starting wind. J. CUSTOMER CODE SM3015 provide two-bit customer code to distinguish different product models. There are four types, that can be set by diode. a. Set code bit to "0", connect diode to COM1/COM2 and SWING/SW1 terminal b. Set code bit to "1", open the circuit.
