Gauges, Lights, And User Controls
POSITION 0 - This is the “Off” position. No power is supplied to the machine.
POSITION I - The brew boiler and other functions related
to making espresso are powered on, but the steam boiler is off.
If you are not planning on using neither the steam nor hot water
functions, this position will save some energy while allowing
full function to make espresso.
POSITION II - The brew boiler as well as the steam boiler are fully functional. Both
are being powered, and once up to temperature you can make espresso or steam milk or
dispense hot water as you desire.
POSITION II & PID OFF - The PID system can be turned off which disables the
brew boiler’s heating function until the PID is once again turned on. This is accomplished
by pressing the PID’s power button. If the PID is turned off when the power switch is in
“Position II,” only the steam boiler is functioning. More details on using PID functions
are discussed in Chapter 12.
Let’s take a tour of the Vibiemme DD’s interface and see what it offers the user in terms of control, moni-
toring, and operating functions:
Power Switch
The Power switch has three positions:
PID Functions
The PID is controlled with the two buttons, one on either side of the PID’s
display on the front panel.
The most basic function uses the right button which turns the PID on and
off. Once the DD has been powered on, if the PID is operational, the display
will show the current brew boiler temperature. If the PID is turned off, the
display will show “oFF.” Detailed information on the operation and control of
the PID’s functions are discussed in Chapter 12. Turning the PID off turns off
the brew boiler’s heating function.
