Important Installation Notice

This control brain unit ships unconfigured from the factory and requires manual setup after installation. Once wired in, you must access the machine’s technical menu and select the correct machine configuration — either DE (Volumetric, heated group) or MN (Manual E61, thermosiphon group) — to match your specific Bezzera model. The unit will not operate correctly until this configuration step is completed. We strongly recommend this installation be performed by a qualified espresso machine technician familiar with Bezzera’s electronic systems.
