The significant feature of digital tube circuit board is temperature variation remote controlling. That is to say, it can preset designated temperature data, and device which is connected to this controller will is activated when it reaches the designated temperature. There is a temperature sensor installing in that board.
We will like to introduce how to set temperature data for circuit board.
Press and hold S1 (about 2 seconds) to enter into automatic working setting. Digital tube display “A40”, at this time, you can set the high temperature 45℃, then, press S2(+) or S3(-) to adjust according to your need. Press and hold S1 (about 2 seconds) to save data and log out automatically. Press S1 again, Digital tube display “b20”, at this time, you can set the low temperature 25℃, then, press S2(+) or S3(-) to adjust according to your need. Press and hold S1 (about 2 seconds) to save data and log out automatically. The correspondent data will flash when we are setting.
You can follow my example of video.
