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

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. When fan controller is on, press SPEED key on panel or remote control
handset and wind grade changes as follows:
OFF
LOW
MEDIUM
STRONG

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).

G. 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.
