Specifications:
Temperature probe parameters: 50K B = 3950
Thermostat temperature zone error: The error depends on the temperature probe, usually 3-5%
Stall alarm minimum speed: 700-800 rpm

Function setting switch description:
TFL (No.1): The lowest temperature channel PWM setting. When the ON state FAN1 PWM minimum value is 40%, when OFF, the minimum PWM of FAN1 is 20%.
TP1 TP2 (No. 2, No. 3): The temperature channel control temperature range is explained below (requires use with the temperature probe):
TP1 TP2 accelerates temperature at full speed
Close 35°C45°C
ON OFF 40°C55°C
OFF 50°C70°C
ON ON 60°C90°C
When the temperature is lower than the acceleration temperature, it is output at the minimum speed; when the temperature is exceeded, it is always output at full speed.
BF1 BF2 (No. 4, 5): Corresponding to the FAN1 FAN2 stall alarm function switch. When the corresponding open channel fan fails, the controller will use the sound and light alarm (working with the beep), the alarm will be automatically eliminated, and the fan will be rotated. If both BF1 and BF2 are ON (ON), FAN1, FAN2 have one or two stops, the controller will alarm!
