On/off and PID controller implemented via software with a microcontroller PIC18F2550. The on/off or PID controllers act through a PWM output on the gate of power mosfet turning on or off a oven heater, maintaining the temperature at the selected value. It’s possible to set the temperature, switch between on/off and PID regulators and change the PID parameters. The software, compiled with CCS compiler, has an anti-windup routine to prevent the windup issue
