To answer the second question, the Gicar controller, such as the RL30, functions can be as simple as controlling the autofill which runs the pump and autofill solenoid/inlet valve which allows water to enter the boiler to automatically to maintain a minimum level. Larger more complex units, such as the Gicar 3D5, control many features such as automating the grouphead dispensing times, allowing automated preinfusion, and such things as Tea dispensing. There are many different boxes that are often custom designed for a specific manufacturers application. Some are very generic in application.
