In short, the user can press the switch S4 of the control list 7G 22 (see FIGS. 3 and 4, and is equivalent to the mode button of FIG. 4) to switch to the Signal state, and press the option switch (see FIGS. 3 and 4). And corresponding to the MENU button of FIG. 4, to first select the fan 3 in the position of the microprocessor _, at this time, the operating state of the fan 3 and the like can be directly displayed on the panel of the liquid crystal display LCD. . %, when the user wants to reduce the running noise, or reduce the speed of the selected control fan 3, directly press the down switch s3 (see Figures 3 and 4, and is equivalent to the DOWN button of Figure 4) Driving the rotation speed modulation unit 24 to output a corresponding pulse width modulation signal to the central control unit 21, thereby achieving the purpose of reducing the rotation speed of the fan 3; conversely, when the user identifies the fan 3 from the panel of the liquid crystal display LCD The rotation speed is too low, or when the temperature value of the heat source measured by the corresponding thermistor R1 is higher than the corresponding warning temperature value, causing the 10 1296752 s state BZ to emit an intermittent alarm, prompting the user to upgrade the selected control fan 3, when the heat dissipation performance, the user presses the value-added switch illusion (see FIGS. 3 and 4, and corresponds to the UP button of FIG. 4), and drives the pulse width modulation signal output by the rotational speed modulation unit 24 to the central control. Unit 21, can achieve the increase of wind: 3 speed into its heat dissipation effectiveness (four). Since the user can adjust the rotation speed of the selected control fan 3 as needed, and can achieve an appropriate balance between the desired energy consumption and the transmission (four) sound, the overall efficiency and the breadth of the divergence efficiency are applicable. Excellent performance. ... , :Si: two, and further adjust the warning temperature value. At this time, the Moonlight Long Fort option switch S1 is about three seconds, so that the value-added switch S2 and the down-value switch S3 are switched from the liquid crystal display (four) LCD iL system to the warning temperature control, on the flashing energy panel. The warning temperature value forms the code to be adjusted; select two: (Γ can press the value-added switch S2 to raise, work,), the source (ie, the microprocessor) warning temperature value, or can = material value Open the target S3' to lower the warning temperature corresponding to the selected heat source. According to the type of the machine and the safe temperature requirement for the operation, 'there is the corresponding scent, and the invitation is played. B B Bz can be accurate and suitable for safe and smooth operation: the overall efficiency of the heat dissipation cost can not be adjusted, Γι effectively improve the conventional technology (see figure) in warning of temperature heat dissipation cost efficiency is not good The fan control display circuit device 2, which has a high failure rate of the machine and a central ==, drives the majority of the fans 3 to 5 to rotate using the month, and utilizes the regulation.
