If you've chosen a fanless R2 Max and are looking for improved cooling performance, this specially designed external cooling kit is the perfect solution. It addresses your cooling needs, ensuring optimal temperature management. In our real-world tests during the recent hot summer, it delivered exceptional thermal performance for the R2 Max.

Button Instructions:

• "+" and "-" Buttons:
• • In operating mode, these buttons are used to switch the display.
  • During parameter settings, they are used to increase or decrease values (long press for continuous adjustment).

• "OK" Button: This button has three main functions:

1. 1. In Operating Mode (Short Press): Enters the fixed output setting, which is the manual speed adjustment. The setting range is 1-100 (%). Press "OK" again to save and exit.
   2. In Operating Mode (Long Press): Enters the temperature parameter settings. Once inside:
      • Use the "+" and "-" buttons to modify parameters.
      • Short press the "OK" button to cycle through the settings items. You can set the following in order (* indicates a number):
        • Acceleration Temperature ("L**")
        • Full Speed Temperature ("H**")
        • Shut-off Temperature ("C**")
      • Press "OK" again to save and exit the settings.
   3. After Power-off (Long press "OK" then power on): Enters the function settings.
      • Modify using the "+" and "-" buttons.
      • Short press "OK" to confirm and save.
      • This setting is used to change the PWM output direction to: Forward/Reverse ("P1/P-1").
      • Press "OK" again to save and exit the settings.

Detailed Temperature Parameter Explanation:

• Acceleration Temperature "L**":
• • Range: 5-94
  • Function: When the temperature rises and exceeds this temperature, the PWM output begins to increase as the temperature rises further.

• Full Speed Temperature "H**":
• • Range: 10-99
  • Function: When the temperature rises to or exceeds this temperature, the PWM output remains at 100%, and the fan runs at full speed.

• Shut-off Temperature "C**":
• • Range: 0-92
  • Function:
    • When the set value is > 0, the low-temperature shut-off function is enabled. When the temperature drops below this value, the fan output is shut off (both the fan power and PWM signal output are turned off simultaneously).
    • While in the shut-off state, if the temperature rises to exceed the acceleration temperature, the fan will restart and its speed will vary with the temperature.
    • If the shut-off temperature is set to 0, the low-temperature shut-off function is disabled, and the PWM and fan power will always be output.

Important Note:

• The difference between the Acceleration Temperature and the Full Speed Temperature must not be less than 5°C.
• The difference between the Shut-off Temperature and the Acceleration Temperature must not be less than 2°C.
• If modifying a parameter value would violate the minimum temperature differences mentioned above, the program will automatically adjust the other two parameters.
