PROGRAMMABLE PORTION CONTROL VALVE WITH SECRET ACCESS MODE SWITCHING

摘要

A microprocessor based portion control beverage dispensing valve is described that can be switched between a dispense mode and a programming mode. In particular, such switching entails the activating of a plurality of switches in a certain order or combination. In this manner reprogramming of the valve can not occur accidentally or by the deliberate actions of individuals that do not know the access sequence.
