A PID (Proportional-Integral-Derivative) controller precisely regulates boiler temperature by continuously monitoring and adjusting the heating element. Unlike a pressurestat, a PID maintains temperature within a very tight range, resulting in more consistent espresso extraction shot to shot. Is this a genuine Rocket Espresso part?
