page 8 * mask option: a. memory or non-memory function can be chosen. b. there are five kinds of wind mode operation. 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 : * mask option: fan controller is off, light key cannot be used. off nor off nor rhy 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 v.2.0 mar 8, 2002 off nor rhy slp slp (nor) (rhy) off nor rhy slp (nor) press light key off light output key SM3015 s am h op microelectronics corp. g?p?t"?! 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. * 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 mode b: timer with non-accumulation led display timer pulse no. 1 2 3 4 four-steps type a b c d three-steps type a b c mode a: timer with accumulation timer pulse no. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 four-steps type a*1 a*2 a*3 a*4 three-steps type a*1 a*2 a*3 v.2.0 mar 8, 2002 SM3015 s am h op microelectronics corp. g?p?t"?! remote fan mcu
page 10 f. swing key:swing1 and swing2 the swing key will not activate when fan contr oller 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). 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. * 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. off sho1 enable (right / left) the sw1 key pressed off sho2 enable (up /down) the sw2 key pressed off sho1(right & left) sho2(up & down) 3d :the swing key pressed v.2.0 mar 8, 2002 SM3015 s am h op microelectronics corp. g?p?t"?! remote fan mcu
