Feature:
1. DC 8-60V wide operating voltage range (here refers to the control panel can work in this voltage range,the actual operation of the controller power and fan is together, it must be in accordance with the fan power requirements, otherwise it will damage the fan).
2. Dual independent temperature control, in turn show the temperature of the two channels (-9.9 ℃ to 70.1 ℃, error <1 ℃)
3. Fan low speed and temperature control zone are set by key, flexible control, set a large range, set the program after the save.
4. Can set the switch stop alarm function (external AC buzzer long, the default off).

Speed measurement: 10-9990 rpm, more than this speed is always displayed 999, resolution 10 rpm, the display unit is * 10 rpm (speed measurement in accordance with the common 2-pole signal fan design,the vast majority of fans are 2-pole signal)
Stop alarm speed: less than 375rpm
Circuit size: 65mm * 65mm * 15mm, positioning hole center distance 56mm * 56mm diameter 3.2mm
Weight: motherboard + a pair of 1-meter-line cylindrical probe total of about 40g, a separate motherboard weight of about 23g.
Wiring Instructions:
The blue screw terminal is connected to the main power supply (the power supply voltage is equivalent to the fan voltage used and is in the range of 8-60V).
Please note that the positive and negative polarity should not be connected. "Channel 1" and "Channel 2" Fan,line order is the power supply negative,power positive, speed feedback, PWM control (see the wiring diagram below);
"Thermal 1" and "Thermal 2" connection NTC thermistor (parameter 10K B = 3950) ,Respectively, with two channel fan temperature control temperature measurement; "beep" jack connected AC buzzer, when the stop alarm,the fan stops the buzzer will be long.
Wiring Note:
The allowable current for a single fan interface is 3A. If you need to control a fan with a higher current,connect the fan power cord directly to the mains (controller control capability is independent of the fan current and only the current capability of the power conductor).
Show Description:
Control panel through the digital display of numerical value,the right side of the four LED digital LED indicates the current value of the meaning of the line,one or two led channel channel temperature and speed (x10rpm),the second line of the two led on behalf of channel two Of the temperature and speed (x10rpm).
In the normal working state, the four values will be displayed in turn according to the order,you can at any time by pressing the "+" "-" button to manually quickly switch the value of the manual switch will stay in this value for a long time and then into the wheel status The You can shield out the display of channel 2 as needed.
Setting Description:
1. Basic speed setting: The basic speed setting is used to adjust the fan speed before the temperature control starts, that is,the speed of the fan below the acceleration temperature. Set the method, in any running state press the "OK" button,then the channel a horizontal two led at the same time light, the digital display of the current set value (10-100),through the "+" "Button to set the size, long press the button can be quickly and continuously modified, set the good press the" OK "button,enter the channel 2 of the basic speed settings, use the same method set and then press the" OK "button to save and exit
2. Temperature control zone and stop alarm settings: normal operation, long press "OK" button until the display L ** (** for the value) after the release button,channel a horizontal two led at the same time, on behalf of (Range 5-94, unit of degrees Celsius); press the "OK" button after setting,enter the full-speed temperature of the channel, and set the speed to the channel. (Set in the range of 10-99,in degrees Celsius); press the "OK" button to enter the channel after a stop alarm setting, "+" "-" "" Bo "means to turn off this channel to stop the alarm," bon "on behalf of the channel to stop the alarm; set after pressing the" OK "button, enter the channel two numerical settings, order and set the way and Channel one is the same ...
When the above settings are complete, press the "OK" button to exit and save the parameters.
3. Channel 2 display Shield setting: Press the "OK" button while holding down the control panel, and press the "2on" (open channel two display) or "2oF" (shielded channel Two display), release the "OK" button, through the "+" "-" button to set the switch shield, set and then press the "OK" button to enter the normal working state.
4. Press the "+" and "-" buttons to power the controller, and press the "+" and "-" buttons while the controller is not powered on.Press "+" or "-" button to switch mode: "F-1" is normal mode, "F-2" is displayed as anti-timing mode,Press "OK" button to exit (automatically save when you exit) can be set.
Set Note:
1. If the speed and temperature range are set, if the operation is done for 15 seconds, the data will not be saved.
2. When the temperature zone is set, the full speed temperature of the same channel must be at least 5 degrees Celsius higher than the acceleration temperature.
When a temperature value is set to cause this condition to be satisfied, the controller will automatically adjust the other temperature value to ensure that the difference is not low At 5 degrees Celsius conditions,this automatically adjust to one-way, for callback need to manually adjust the other temperature value.
3. Channel two shielding display settings only affect the working status of the data display, channel two control and parameter settings are not affected, the normal work
Note:
This is a four-wire PWM fan controller that can only control fans that comply with the Intel 4-wire fan specifications (the majority of 12-48V four-wire fans are supported),can not control the 2-3 line fan, can not turn off the fan.caveat! The The : Although the controller can work between 8-60V, but the actual power supply voltage must meet the fan operating voltage,such as control 12V fan must use 12V power supply, the wrong choice of power may burn the fan and damage the control board!
Frequently Asked Questions:
1. Power is not displayed
Voltage is not appropriate, the power is reversed ---- controller can be run under DC8-60V input,please determine the power supply voltage and polarity is correct (pay attention to the power supply voltage and fan voltage).
2. Temperature display always shows -9.9 ℃, the actual temperature is not so low,or show the temperature and the actual difference is very large.
Corresponding channel probe is not connected, the probe is bad or damaged, the probe parameters are incorrect - check the probe.
3. The fan does not turn
Fan line order error ---- Please note the fan line order power cord.
There is a part of the fan when the PWM value is lower than 20 will stop ---- increase the manual speed value.
4. The fan is running at full speed, can not control, does not show the speed
Fan line sequence error (line and control line reversed) ---- exchange fan control line and speed line (in addition to the power line outside the two lines).
Fan non-conventional PWM fan, fake or fake or fan failure ---- replace fan
5. The fan can be normally controlled, but the speed is not displayed
The fan speed line (third line) is not reliably connected - check the wiring
Fan no speed signal or fan speed output port failure ---- replace the other fan or no longer ignore the speed display
5. Fan speed changes in reverse
Fan is anti-timing fan, forward to see the installation instructions Article 4, modify the controller operating mode.
