2. Simple replacement, no complex wiring, quickly restore the function of the electric fan, even non-professionals can also be easily operated 3. Adopting high-efficiency electronic components, compared with the traditional circuit boards can effectively reduce energy consumption, saving electricity costs, environmental protection and economy. 4. Selected high-quality electronic components to ensure stable operation of the circuit board, reduce the frequency of maintenance, improve overall performance and reliability Parameter: Control socket: MODE short: A-key public terminal, B-wind class, C-timing, D-rocker, E-speed, F-switches Interface definition : MODE disconnect: A-stop button, B-C-D were connected to the wind speed, EF does not connect Using method. 1. open / wind speed: standby state, press the “open / wind speed” key, the fan wind work, and then press this button fan can be “large - medium - small” cycle work 2. Shake the head: under the working condition, press the “Shake the head” key to enter the shaking head state, and then press this key to close the shaking head, without shaking the head of the motor can not use this function 3. Timing: working condition, press the “Timing” key, according to “0,5-1-1.5-2-2.5-3-3-3.5-4-4.5-5-5.5-6-6.5-7-7.5-0” this order cycle timing 4. Wind class: under working condition, press “wind class” key, you can convert “natural wind - sleep wind - normal wind” working mode 5. Shutdown: working state, press this key can turn off the fan all working conditions Package include: Fan circuit board *1 Remote control *1 (batteries not included) Wire *1
