  It is a PWM four-wire fan temperature control speed regulator.The controller can only control the 12V standard 4-wire PWM fan.The internal signal of the 4-wire fan is controlled by the PWM signal.The fan power is not turned off,the fan voltage is not changed,and the 2-wire,3-wire,and non-standard PWM fans cannot be controlled.
  1>.Programmable controller
  2>.It has clear indicators
  3>.It supports the control of anti-sequence fans
  4>.It is light and portable,has a low heat capacity,and is safe and durable.
  1>.Product Name:PWM Four-wire Fan Temperature Control Speed Regulator
  2>.Working Voltage:DC 12V
  3>.Consumption Current:20mA
  4>.Fan Current:3A
  5>.PWM Output:10%~100%
  6>.Work Temperature:-10℃~60℃
  7>.Work Humidity:5%~95%RH
4.Control method of anti-sequence fan:
  1>.Turn off the power and remove the fan first. Long press SET Button to power on the controller.
  2>.Long press SET Button for 3 seconds,release it after the three lights enter the double mountain state at the same time,and the single indicator light double flashes,then enter the mode setting state.
  3>.The controller is divided into three working modes,corresponding to indicator lights 1~3 double flashing.It can be switched by short pressing the SET Button.After setting,long pressing the SET Button can save and exit the setting mode and automatically return to the normal working state.
  1>.Normal PWM fan control mode (default mode), for four-wire fan control according to standard Intel specifications.
  2>.Conventional anti-sequential PWM fan control is used for most anti-sequential four-wire fan control.The speed of the fan is reversed in normal mode control,and the control line is full speed when connected to the negative electrode.
  3>.Anti-sequence fan 80% mode is used for a rare type of anti-sequence fan.This type of wind speed changes in the normal mode before the wind changes,and the control line does not rotate when it is connected to a negative stage.
6.Normal Operation:
  1>.Click the SET Button to increase the bottom line output by 5%.
  2>.Double-click the SET Button,the bottom line output will be reduced by 5%,run for 20 seconds after changing the value,and automatically save the parameters after the middle indicator light stops flashing.Press and hold to save and enter the temperature control setting.
7.Temperature Control Setting:
  1>.Acceleration temperature control setting (slow flash):Click and double-click to raise and lower the setting value,long press to hold and enter the acceleration width setting:
  2>.Acceleration width setting (quick flash):Change the value by double-clicking, then press and hold to save and exit the temperature setting.
  3>.The bottom line is 20%,the acceleration temperature is 35℃,and the acceleration width is 15℃.When the probe temperature is lower than 35℃,the output signal is always 20%,and when the probe temperature exceeds 35℃,the controller smoothly increases the output signal according to the temperature rise.The fan speeds up.
  4>.When the probe temperature reaches or exceeds 50℃ (35℃+15℃),the controller outputs a full speed signal,the fan is at full speed,and the actual speed of the fan will vary slightly depending on the specific performance of different fans.
  1>.1pcs PWM Four-wire Fan Temperature Control Speed Regulator
  2>.1pcs Thermal Probe
