Operating instruction

The master switch of transmitter realizes fan and light control (Mark 1) :

  • the factory default state for fan status. When the lights are turned on again, the brightness and color temperature are the state before the lights are turned off.
  • boot 30 seconds, long press this button for 3 seconds, to complete the remote control code. When the code is successfully matched, the light flashes. Before the code is matched, the light is on: light off for 1second->light on for 1 second -> light off; Before code alignment, light off state: light on for 1 second, light off.
  • in fan respectively in high/medium/low, light work mode. Press key once. Within 30 seconds, the fan stops running and shuts down. How to press the key twice in succession, the fan should run in high speed gear with in 30 seconds while the light shines.
  • the fan at the stop, light work mode. Press key once. Within 30 seconds, the fan stops running and shuts down. Press the button twice in a row, the fan needs to run in high speed within 30 seconds, and the light will glow.
  • in fan stops, the lights work mode. At this time, press the key once. With in 30 seconds, the fan should be running at the high level and the lamp should glow white. Press the key twice. With in 30 seconds, the fan stops running and the lamp must be turned off.
  • in fan respectively in high/medium/low-grade, working mode, the lights went out at this point according tot he national health 1, 30 seconds, fan stop running and lights. Press the key 3 times continuously, the fan runs in high speed, and the light shines.
    Note: The color temperature may change if the light switch is too fast.

Fan Gear Control (Mark 3)

  • is divided into high, medium and low third gear, could wind speed buttons on the transmitter. After receiving the transmitting signal, the receiver controls the output of the AC motor to realize the fan speed of different gears.
  • each file conversion time in less than 6 S.
  • ask fan speed in the range of 10% of the set speed. Speed can overshoot.
  • hold can be directly to the keys can directly control the fan fan gear, and don’t need to push the fan switch must first.

Lighting Control (Mark 3)

  • only under the conditions of open LED lamp, can adjust the brightness.
  • from the dark to the light or the brightest to the dark, need long keys 7 seconds.
  • long key defines the longest (the remote control can be 10 seconds), brightness will change,
  • control law:
  • Gradually change light -> Brightest -> Gradually change dark -> darkest -> Gradually change light->… During the gradient process, press the main switch for 10 seconds and no longer adjust the brightness.
  • can also many times short key, brightness will gradually change according to the rule.
  • power 3.6 W when minimum brightness, high power 30 W + A1 brightness. (Power of the board when the fan is not turned on) The minimum brightness power is 3.0W, and the maximum brightness power is 33.1W.
  • the factory default brightness is the brightest (power 31.1 W).

Color temperature adjustment (Mark 4)

  • six color temperature, color temperature adjustment by the launch button.
  • only open the LED lights, that can adjust the color temperature.
  • each press buttons, color temperature will change again.
