QUICKSTART GUIDE
DON'T REVERSE THE LOGIC. OTHERWISE IT WILL NOT WORK.
If the temperature controller is used to control a heating device, please set ON < OFF.
If you use the temperature controller to control a cooling device, please set ON > OFF.
CONTROL A HEATING DEVICE:
For example, turn on a heater at 40F degree and turn it off at 50F degree.
Step-by-step setting:
1,  Press and hold SET button for 3 seconds, release the button when screen display ON
2, Press SET button once, the number displayed is the heater turn-on temperature
3, Press UP or DOWN button to adjust the number to 40. Hold UP or DOWN button to rapidly adjust the number.
4, Press SET button once to save and quit. Screen displays ON.
5, Press UP button once and the screen displays OFF
6, Press SET button once, the number displayed is the heater turn-off temperature.
7, Press UP or DOWN button to adjust the number to 50. Hold UP or DOWN button to rapidly adjust the number.
8, Press POWER button once to save and quit.
Now the heater is under controlling.

FAQ: I set ON=40 and OFF=50. But there's no power out when the temperature is between 40 and 50 degree.

IS THE CONTROLLER DEFECTIVE?
A: THIS IS USUALLY BECAUSE THE CURRENT TEMPERATURE WHEN YOU PLUG THE HEATER IN IS

RIGHT BETWEEN THE DESIRED RANGE. SO THE CONTROLLER DON'T NEED TO OUTPUT POWER.
PLEASE NOTE THE HEATER WILL ONLY BE TRUNED ON WHEN TEMPERATURE DROPS BELOW 40F

DEGREE. WHILE THE TEMPERATURE IS HEATING UP FROM 40F TO 50F, THE CONTROLLER KEEPS

OUTPUTTING POWER. IT WILL CUT OFF THE HEATER ONCE 50F IS REACHED. THEN THE

CONTROLLER REMAINS NO OUTPUT UNTIL THE TEMP DROPS BELOW 40F AGAIN. SO

PLEASE DON'T CONSIDER THE CONTROLLER SHOULD ALWAYS OUTPUT POWER WHENEVER

TEMPERATURE IS BETWEEN 40F AND 50F.

CONTROL A COOLING DEVICE:
For example, turn on a fan at 100F degree and turn it off at 80F degree.
Step-by-step setting:
1,  Press and hold SET button for 3 seconds, release the button when screen display ON
2, Press SET button once, the number displayed is the heater turn-on temperature
3, Press UP or DOWN button to adjust the number to 100. Hold UP or DOWN button to rapidly adjust the number.
4, Press SET button once to save and quit. Screen displays ON.
