Specifications:

Power supply: DC 12V; the maximum range 11-14V; too low voltage displaying Lu; too high voltage displaying Hu; protection closed output

Output current: single channel maximum continuous output current 1.2A; double channels being both used at the same time current cannot exceed 2.0A; not suggesting using the fan with current being lower than 0.15A

Work efficiency: 90% (input 12V; output double way 8V 0.8A)

Reversely connected protection: short circuit reverse connection protection; power supply being connected reversely will burn out input copper foil
Over current protection: no over current protection; please note insulating installation; power up it after the wire is well connected to avoid output short circuit!! (only paid maintenance will be offered for overload and short circuit damage)

Thermal resistance parameters: NTC  10K B=3950

Measurement temperature error: 1%-0.5℃; after combining 1% probe, the maximum error 2%-1℃

Board dimensions: 92mm*54mm (width*height); location hole place: 87mm*47mm diameter 3.4mm

It automatically take turns to display channel 1 temperature, rotation speed, and channel 2 temperature, rotation speed under normal operation; quickly switch the display by pressing the "+" "-" button.
 
Parameter Setting:

Manual rotating speed setting (the minimum rotating speed under temperature control):
Press “OK” button to enter into rotating speed setting function; FAN1 2 indicator lights lighting up at the same time stands for current adjustment being fan 1’s output size and by pressing the “+”&“-” button to adjust it with minimum 1 & maximum 100. After the setting, press “OK” button to enter into fan 2’s output size setting; after the setting, press “OK” button again to exit and save the parameters.

Temperature control and stop-rotating alarm settings:
 
Under normal operating state, long-press “OK” button to enter into temperature control and stop-rotating alarm settings; indicator light on the right indicates corresponding setting channel; corresponding setting parameter display, meanings, and range (“**” stands for digit ):
L** accelerating speed temperature setting, range 5-94℃; lower than H** at least 5℃, or adjust up H** by linkage.
H** full speed temperature setting; range 10-99℃; higher than L** at least 5℃, or adjust down L** by linkage.
F** fan being shut off temperature; minimum 1; maximum limitation is lower than L** 2℃; when F00 is set, fan is not shut off.
bON / bOF: channel stop-rotating alarm on / off.

Adjust the setting value by pressing “+”&“-” button; press “OK” button to switch setting parameters; set the channel 1 according to the above sequence first, channel 2 second; press “OK” button at last to exit and save parameters.

Supplementary Instructions: when channel temperature reaches L** after fan being shut off function is started, fan is started at minimum speed; it will accelerate with temperature increasing; when channel temperature is lower than F**, fan is shut off. Corresponding channel stop-rotating alarm will automatically block shut-off status’s rotating speed check.

Shutting off channel 2 display:

One channel is needed for some application and now channel 2 can be shut off; the setting method: keep pressing “OK” button to make it be powered up with controller not being powered up; controller entering into channel 2 displays setting status; modify the setting by pressing “+”&“-” button; 2ON / 2OF stands for channel 2 display / no display; after the setting, press “OK” button to save it, exit and enter into operating status. 

Note: after channel 2 display being shut off, it will not display channel 2’s rotating speed and temperature only on LED display; it will not affect channel 2’s function.

Package included:

1 x Fan temperature controller
2 x Temperature probe
1 x Buzzer
