This app is for the LONDINIUM model R lever espresso machine that has the pressure transducer (digital pre-infusion) module and wireless dongle installed. It will not have any effect on a LONDINIUM model R that does not have both of these components installed. This app allows you to alter the pre-infusion pressure and the pump delay from your phone or tablet. Low pre-infusion pressures should be matched with a low pump delay value and longer pump delays for high pre-infusion values. Dark roasts require low pre-infusion pressures, medium roasts medium pre-infusion pressures, and light (nordic or filter) roasts require high pre-infusion pressures. If you have any questions please do not hesitate to contact LONDINIUM Espresso.
