The open board temperature controller is specifically designed with a proportional integral control algorithm to provide the most precise control to thermoelectric (Peltier effect) modules at the most economical price. The H bridge control provides a seamless transition between heating and cooling, eliminating dead spots. A red LED for heat and green LED for cooling indicate mode. Pulse Width Modulation controls the power level in the thermoelectric module at a base frequency of 900Hz. Power resolution is one of ±255 steps in the load circuit control.
