PROGRAMMING
This is the second screen of the display: BG1 Temperature Control
Line 1 of the BG1 Temperature Control screen indicates the current temperature being recorded
by the first position brew group's temperature probe, LOW in this example. Once this temperature
reaches the set point, it will continuously cycle up and down by small increments as the electronics
balance the temperature.
Line 2 is indicating the set point of 203.0F (95.0C).
Line 3 indicates the length of time that the stage 1 timer (timed preinfusion) will run.
Line 4 indicates the length of time that the stage 2 timer will run. This option will ONLY be available on
machines that are equipped with pump bypass systems. See page 22 for more information.
To change the temperature set point, press the button for line 2. The current temperature setting
(203.0F) will begin to flash. To alter the temperature, press the '▲' or '▼' buttons until the desired
temperature is reached. Press the button to the left of line 2 to confirm the temperature point. The
number will stop flashing.
Line 3 indicates the amount of Stage 1 or "Line Pressure Pre-infuse" time that will elapse before the
pump is initiated. Line pressure can be altered with either a pressure regulator or a boost pump.
To change the Stage 1 time, press the button associated with line 3. The current time will begin to
flash. To alter the time on the indicator, press the '▲' or '▼' buttons until the desired time is reached.
Note, setting the Stage 1 timer to 00 will automatically set the Stage 2 timer, if present, to 00). Once
the desired time is reached, press the line 3 button to save the Stage 1 time. The number will stop
flashing. If a time is set for Stage 1, the user will be able to activate the timed preinfusion program by
moving the group head handle all the way to the left into the brew position. The brew valve will open
and the pump will turn on after the designated number of seconds for Stage 1 time have elapsed.
Line 4 indicates the amount of time that the pump bypass (if present) will operate. Stage 2 time be-
gins once the Stage 1 time has finished. Operating the bypass while the pump is running, as occurs
in Stage 2, allows a settable, reduced pressure point between line pressure and pump pressure. To
change the Stage 2 time, press the button for line 3. The current set time will begin to flash. To alter
the time on the indicator, press the '▲' or '▼' buttons until the desired time is reached. Once the de-
sired time is reached, press the button associated with line 4 to confirm the Stage 2 time. The number
will stop flashing.
To cycle to the next display screen in the menu level, press the button next to line 1.
