Specifications:
1.Operating voltage: DC8-60V (must be equal to the fan voltage, 12V fan, but if you use 24V power supply fan will burn)
2.Current: Dashboard Working current 35mA (12V) 22mA (24V)
3.Control: not fan the current limit, but the board fan connector pins do not exceed 4.the maximum 3A current, use more current fan set the fan power cable is connected directly to the mains!
5.Control Output range: 10% -100% (this is the signal output range, the situation depends on the fan performance)
6.Temperature Probe Specifications: NTC 10K B = 3950
7.Temperature measurement: -9.9 ℃ to 70.1 ℃ error <1 ℃ (use 1% precision probe)
8.Temperature range temperature zone: accelerating temperature 0-60 ℃, full temperature 10-70 ℃
9.Speed measurement: 10-9990 rpm, more than is always displayed maximum resolution of 10 rpm, display units * 10 rpm (speed measurement according to the most common 2-pole signal fan design, the vast majority of fans are 2 pole signal)
10.Stall warning speed: less than 375rpm

Wiring instructions:
Blue screw terminal connections the mains (power supply voltage equivalent to the fan voltage use, and in the 8-60V range), please note not to take the wrong polarity; "Channel 1" and "Channel 2" two 4P socket connection fan, power supply line sequence is negative, positive power, speed feedback, PWM control (for details, see wiring diagram below); "thermal 1" and "2 thermal" Connect NTC thermistor (parameter 10K B = 3950) , respectively, with two channels of temperature control temperature fan; "beep" jacks AC buzzer, when you turn the alarm stops, the fan will stop the buzzer sounding.

Wiring Note:
The maximum allowable current single fan interface is 3A, if you need to control the higher current fan, set the fan power cord directly connected to the main power supply of the above (and fan controller capability independent of current, but to consider the power conductors current capacity)

Display Description:
Dashboard via digital display value, the right of the four LED digital tube digital tube current value indicates the meaning of the first line of each table led two temperature channels and a rotational speed (x10rpm), the two led the second line of distinguished representatives channel two of temperature and speed (x10rpm). Under normal operating conditions will follow the order of the four values ??displayed in turn, may at any time by pressing the "+" "-" button to quickly switch to manual values ??manually switch will stay at this value for a long time re-entering the round was state . It can be masked as required channel II display.

Setting Note:
1.Under setting state. Speed ??and temperature zones, if more than 15 seconds is not operated, the automatic exit without saving the data.
2.When the set temperature zone, full temperature must be higher than the same channel accelerated temperature of at least 5 degrees Celsius, a temperature value when setting causes this condition is not met, the controller will automatically adjust the temperature data to ensure compliance with the other difference is not low in conditions of 5 degrees Celsius, this is automatically adjusted to a one-way, and if you need to manually adjust the callback another temperature.
3.Channel two masked display settings only affect working state data show that two of the control channel and parameter settings are not affected, the normal work.

Package Included:
1x 4-Wire Temperature Control PWM Computer Fan Speed Controller
2x 1 meter temperature probe
1x Diameter 12mm length 10cm buzzer
