Espresso Settings & Dial-In Guide

With dual PID temperature control (88–98°C), you can fine-tune extraction temperature alongside grind size for precise dial-in. The adjustable OPV lets you fine-tune brew pressure beyond the factory setting. Allow 20+ minutes of warm-up time for temperature stability.
