RTS511B FAN CONTROLLER Features - Wide operating voltage range: 3.5V - 5.5V - Use 32768Hz quartz crystal as time base - Three wind modes: - Constant-speed wind, Rhythmical wind & Sleep wind - Three wind grades for each wind mode: - Soft, Medium & Strong wind - Two types of selectable timing function - Summable, non-summable - Special protections preventing key-in mistakes - Power-ON Reset - One key controlling “Fan Swinging” and “Lighting” functions - Low power consumption - Combined with RTS715-2, which functions an infrared remote controller for fan - Supplying a select pin to enable or disable sleep mode General Description Similar to RTS510B, the fan controller RTS511B, embedded with a remote-control receiver, is a CMOS LSI designed for fan controller applications. It is a remote control system with three wind modes, three wind grades and six timing functions achieved by combining RTS511B with RTS715-2. In the Rhythmical wind mode, the wind speed is programmable. For example, it can be be soft→ medium → strong→ soft etc., according to the program. In Sleep wind mode, the wind speed automatically decreases to help fall asleep. There are six types of fan controller as shown: (bonding option 1, option 2 and option 3) Function Bonding Bonding Bonding Light & Select Timer Type \ Option1 Option2 Option3 Swing 0 1 0.5 →1→2→4 Light is RTS511B-000 F F GND summable Indepen- Enabl Disabl 1→2→4→8 dent. e e RTS511B-011 F VDD F Swing is sleep sleep non-summable depended wind wind 1→2 →4 RTS511B-101 VDD F F on “A2”. non-summable * Dependent: Only when fan controller is initiated by "A2" key, "Swing" is started by pressing "A5" key.

Nor is a stress at the listed values allowed to persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof.

RTS511B Operation Function There are two ways of sending control signals: from the keypad of the control panel and the infrared ray receiving module. There are six operations on these signal control: Turn off, Wind speed, Wind mode, Timer setting, Head swing, and Lighting. When control signals other than "Turn off" are received, the control system echos a "Beep" sound. If any two or more keys are simultaneously pressed, neither of the corresponding functions will be activated. If any key is pressed over 6 seconds, the fan controller will automatically echo four "Beep" sounds for warning and then power Off. The "Speed" function starts the fan, initiating the speed is at "Soft wind". When pushing the "Speed" key, the sequence of the wind speed follows “Soft→ Medium → Strong…”. The sequence of the "Mode" is "Constant→ Rhythmical→ Sleep". In the later section, the detail "Speed" & "Mode" function graphs are shown. Note: Strong wind begins to move one second before soft wind starts.
