  • Tempmaster Mk2: Temperature Switch Circuit Board Source

Note: solder wires onto the input 12V areas instead of attaching the plug component. This will improve power supply compatibility considerably.

Increasing the range of the variable resistor will increase the maximum reference temperature that can be designated.

Increasing the resistance between pin 3 of the comparator and LK1 will increase the hysteresis band.

  • 12V 0.5A Power Supply Source Currently under testing
