7. Select the batch icon next to the size you wish to modify (small, medium and large).
8. The screen that will appear has a menu of icons that represent settings you can enable, disable or modify.
VOLUME - This icon allows for volume adjustments. Each batch size, small, medium, and large will
have adjustable brew volume ranges to choose from. Pressing SAVE after the number has been
entered will confirm the change and exit back out to the recipe parameter screen.
BYPASS (ITCB HV Only)- This icon adjusts the bypass as a percentage of the total brew volume.
This means the set percentage will bypass the coffee grounds through the funnel to the server. If
bypass is used in a recipe, it will only turn on after 30 seconds of sprayhead time. The operator will
press SAVE to confirm their entry, which will exit them back to the recipe parameter screen.
DILUTION (Tea Recipes Only) - Dilution is used in tea brewing to dilute the concentrate of tea
brewed in the funnel. The user will set the amount desired in ounces or ml. The user can adjust
the volume by touching the text field and prompting the numeric keypad or use the plus or minus
butttons to increment or decrement the volume. Save confirms the change and exits the user back
to the recipe parameters screen. The arrow will just take user back to the recipe parameter screen.

PROGRAMMING (cont.)
DILUTION DELAY (Tea Recipes Only)- This feature allows the user to set a time when the dilution
water should turn on after a brew cycle has been initiated. The user can adjust the time by touching
the text field and prompting the numeric keypad or use the plus or minus butttons to increment
or decrement the time. Save confirms the change and exits the user back to the recipe parameters
screen. The arrow will just take user back to the recipe parameter screen.
PRE-INFUSE - Pre-Infusion is defined as two parts; the first initial wetting of the coffee grounds
and the first initial “OFF” period before the rest of the brew cycle begins. The operator will have
the ability to brew with just pre-infusion only, if they prefer to do so. The operator must enable the
feature by selecting the checkbox. To set an “ON” time, the operator can select the text field. This
will prompt the numeric keypad to enter the desired time. To confirm a change, the operator must
press the SAVE button. The batch size icon in the upper right hand corner of the screen will allow
the operator to cycle between batch sizes. If the operator switches to a different batch size, those
parameters must be updated in the fields. Disabling the feature will gray out the white text fields.
The operator will not be able to adjust this setting unless the feature is enabled.
PULSE BREW - Pre-infusion and bypass settings will be taken into account if set already. The
operator will use the text fields to enter times. When entering the sprayhead on time, the ounces or
milliliters (depends on units set on the machine) being dispersed for that amount of time will display.
The quantity of water dispersed will be larger the longer the time is on. If the time is decreased, the
volume should lower as well. The volume displayed will be gathered from an average of both the
left and right sprayhead calibration settings. When setting the pause time, the operator is choosing
how long to turn the sprayhead off; this is not an accumulated time. This time is the length that the
sprayhead will turn off during the pulse routine then turn back on. Both on and off times will have
limits the operator is able to set depending on the parameters of the recipe. When configuring the
routine, the total brew time will change to be shorter or longer depending on the routine settings.
Longer pause times extend total brew time in most cases. The Auto calculate button will automatically set a routine based on the parameters for the recipe. Save will confirm and save the settings
for that recipes batch size. The batch size icon will cycle through the other enabled sizes to allow
the operator to set the pulse brew for a different size batch from this screen.
Reset - Creates an auto pulse brew is a set routine of 7 pulses that has been calculated by
parameters the operator has set. The operator must specify the batch volume, percentage of bypass,
pre-infusion time, and drip time. The pulse off time is calculated off a 60 second additional Brew
time for the 6 off pulses between the 7 on pulses. Off time = 10 sec / pulse = 60 sec / 6 pulses
Manual Pulse Brew - If a operator would like to adjust the brewing time which they have been
given in Auto pulse, they can change or make adjustments to the remaining on/off times. Doing this
can extend or shorten the brew time originally calculated for the Auto Pulse brew thus the operator
is now going to control what on and off times the brewer will use to make a pulse routine.
SMARTWAVE® - This is a brewing feature that alters the trajectory of water coming out of the
sprayhead in order to enhance uniformity of extraction. This is accomplished by activating the
air pump during the sprayhead on times only. When the sprayhead valve is on, the air pump will
activate and blow a pulse of air which will widen the pattern of water that hits the bed of coffee.
The operator will be able to set the SmartWAVE from 1-14. The plus/minus buttons will increment
and decrement by 1. Each number represents the air pump turning on twice during that brew cycle.
1 (2) - 14 (28). There will always be a blowout period of 5 seconds at the end of the brew. This will
evacuate water in the sprayhead to help avoid lime build up.

PROGRAMMING (cont.)
DRIP TIME - Drip time is the time allotted to allow for any excess coffee to drip from the funnel after
a brew has been completed. The operator will be able to add up to 5 minutes worth of time. If no
time is added the brew will complete and funnel locks will raise.
FRESHNESS - This time is used to help control beverage quality. An alert will pop-up full screen and
state that the recipe has expired. Once acknowledged, the operator can brew as normal.
REVIEW - Selecting this icon will give the operator another method of setting a recipe. This method
uses a table layout that shows the parameters and the values that are set. Selecting the white area
will take the operator directly to the edit page for that parameter. The operator can change the value,
SAVE, and exit back to the recipe review screen.
MACHINE SETTINGS
Selecting Brew Settings will take the user directly to the Set Temperature screen. This screen allows the setting of
the temperature that the tank attempts to heat to and maintain, and at what threshold the system allows brewing
to occur (if brew lockout is on). The tank set temp is the set point that the heater tries to control to, and the ready
temperature is how much below the set temp that the system allows brews to occur, depending on whether or
not the brew lockout (also known as temperature lockout) feature is active.
