Fuji PID Controller - La Marzocco This is a special order item, typically requiring 6-10 business days for processing prior to shipping. Fuji-manufactured PID controller used in La Marzocco equipment (La Marzocco part #E.1.011). This is the brain of the boiler temperature control loop, when it fails, expect erratic temperature swings or a boiler that won't reach or hold set point. COMPATIBILITY Fits: La Marzocco equipment using the E.1.011 PID controller INSTALLATION A technician-level electrical job; the manufacturer's instructions guide covers programming the parameters after installation. PRO TIPS After swapping the controller, verify the PID parameters (setpoint, PID gains, alarm limits) against the instruction guide rather than assuming factory defaults match your machine's prior tuning, a mismatched parameter set is a common cause of temperature overshoot right after replacement.
