BASIC SETTINGS

The various programming options of the DRIVE are explained below.
7.1

Menu navigation

The menu is accessed by pressing and holding the left and right buttons simultaneously. The left button
can be used to switch through the settings, the right button confirms the selected menu item. Settings
can be adjusted with the right and left button and are automatically saved after 5 seconds. Therefore,
changes should be made quickly.
7.2

Flow Control

The Profitec DRIVE is equipped with a "Flow control" that allows the water flow to the brew group to be
regulated and also changed during brewing. The resulting brewing pressure can be read off the built-in
brew group pressure gauge and changed by turning the ball handle. This makes it possible to prepare
espresso with different flow and pressure profiles.
Pressure profiles
To prepare an espresso with the stock flow (regular flow rate of the Profitec DRIVE), the "Flow Control"
valve should be opened with 1 ¼ turns. This allows classic espressos to be prepared with a rapid pressure
build-up to around 9 bar. The water output at this setting corresponds to about 10 - 12g per second.
By adjusting the "Flow Control" before or during espresso preparation, the taste of the beverage can
be influenced. Closing the "Flow Control" during pressure build-up allows for a significantly longer
preinfusion to be integrated into the preparation, suitable for very light or fresh roasts with less
channeling. For more information on preinfusion, see chapter 7.6.
Pressure profiles can also be tailored similarly to lever machines or optimize the preparation of different
beverages (Ristretto, Lungo, etc.). To approach pressure profiling, it is recommended not to change any
parameters (coffee, grind size, quantity, etc.) except for the "Flow Control".
The pre-brew chamber of a traditional E61 brew group is not used in the Profitec DRIVE to achieve a direct
influence on the brewing pressure.
Optional accessories
To precisely control the preinfusion and to ensure high repeatability, it is recommended to use a
responsive, fine scale, and a bottomless portafilter.
7.3

Brew temperature

The desired brewing temperature can be set in the menu item "Brew Temperature". This is a target
temperature. The preset default value for the brew temperature is 92 °C (197,6 °F).
7.4

Activate/deactivate steam boiler

With the DRIVE, you can turn off the steam boiler to save energy, especially if you only prepare espresso
drinks. The default setting is „ON," and if you want to deactivate the steam boiler, set the value to „OFF."
