The VI also allows you to control the heater output manually by setting the manual override. Reason for the questions. About 6 months ago I had headers installed on my car and of course, along came the CEL. This project uses a PIC microcontroller to automatically control the temperature of an area. PID Controller. PID mathematics can be complicated, but (within limits) PID can compensate for thermal resistance and thermal capacitance in systems to yield precise temperature control.
