Simple 5 region thermostat with PIC16F690 using NTC's as a sensors driving 5+1 relays. Thermostat do not use PID control but a simple on/off with hysteresis (like ordinary mechanical thermostat would - note that function in source that decides to turn heater on/off is called pid() but that's not how decision is made). Note that it's designed to measure 5 regions and control 5 groups of heaters but *all* of them are trying to reach *same* temperature. If a region goes too much off the set...
