5.Temperature Parameter Set:
1>. ` L** ‘ Accelerated Temperature: Set range is 5~94. PWM output increases with temperature rise when the measured temperature higher than` L** ‘.
2>. ` H** ‘ Full Speed Temperature: Set range is 10~99. PWM keep output 100% and fan keeps running at full speed.
3>. ` C** ‘ Shutdown Temperature: 3.1>.Set range is 0~92. 3.2>.Enable this function if ` C** ‘ >0; 3.3>.Disable this function if this parameter is set to ` C00 ‘. Fan keep work and PWM keep output. 3.4>.Turn OFF fan( both fan power and PWM signal are turn off) ; 3.5.>.At Shutdown State: Fan restart and speed changes with temperature if when the measured
temperature higher than ` L** ‘ Accelerated Temperature.
