By making combinations with the B(blue), G(green), R(red) jumpers, we can obtain different colors on the display:
The MOLEX connector can be found in the top right corner of the PCB:
In the middle, we can find the alarm buzzer; the alarm is turned on in case one of the recorded temperature passes over 70 degrees Celsius or when one of the fans does not rotate when powered by a voltage higher than 6.5V:
Here are the different colors that we can obtained by playing with the jumpers:
If we modify the position of the “Select” jumpers, we can tell the controller to display the temperature in Celsius instead of the voltage:
When a probe is connected, the controller will display right away the respective temperature:
