SM3015 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 SAMHOP Microelectronics Corp. SM3015 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 W hen 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.

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 SHO1 enable (Right / Left) The SW1 key pressed OFF 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.
