The three-position power switch on the Modbar module has three separate functions, as illustrated in
the following image.
0 - Off
In this position, the module is in the off position.
I - Standby Mode
In this position, the module is in standby mode. When in
standby mode, all operations function as normal, but no power is applied to the
heating elements. This mode is used for priming the system upon installation, and
can also be useful for some diagnostic applications.
II - Operating Mode
In this position, the module is in operating mode. Power is applied to the heating
elements, and all functions operate as normal.

Upon installation, the Modbar module must be primed before use. This is accomplished by the following
steps.
●Ensure that filtered water is supplied to the module.
●Ensure that the power switch is in the off position.
●Ensure that the module power cable is plugged into its appropriate power source.
●Turn the power switch counter-clockwise to place it in standby mode.
●Actuate the tap handle in manual mode, as described in the “Dispensing Operations” section of
this guide.
●After water begins to pour from the tap (This may take some time on a new system) allow water
to flow for at least 30 seconds to ensure that the system is primed.
●At this point, it is safe to turn the switch clockwise into operating mode.
During general use, the module is already primed, and it is not necessary to prime the system. To start
the module, follow these steps:
●Ensure that filtered water is supplied to the module.
●From the off position, turn the power switch clockwise to place it into operating mode.
●At this point, the elements will begin to heat. When each heat zone reaches set temperature,
the module is ready for use.

The touch screen is used for selecting and displaying data. The multi-function encoder is used for
editing data. The functions of the encoder are shown below:

OPERATING MANUAL ESPRESSO SYSTEM
www.modbar.com Document 001-0040-1.1| Software Version 2.0
9
Process value: This is the current value in degrees of the active heat zone (selected by the heat zone
button).
Set temperature: This is the current set-point value in degrees for the active heat
zone. To change the set temperature, simply touch the red value on the screen
and the value will be highlighted. Rotate the encoder left or right to change the
value in 1-degree increments. Press the joystick up or down to change the
temperature in 1/10 degree increments. Press the center button on the joystick to save the change.
(These temperatures are saved to the currently selected profile)
Ready indicator: This square icon indicates whether the machine is at temperature to dispense. When
first starting the machine, the indicator will remain red in color until all temperature zones are heated to
set temperature. Once all zones are at temperature, the icon will turn green, indicating that we are now
ready to dispense.
Heat zone: In automatic temperature mode, this button has no function. In manual temperature mode,
pressing this button cycles through the 3 heat zones on the espresso system: Inlet Boiler, Outlet Boiler
and Brew Head. (Refer to “Advanced preferences screen page 2”)
Settings button: This button navigates to the main settings screen.
Machine status: Displays the current status of the module & tap.
Machine name: Displays the machine name (user editable in advanced preferences).
Active pressure profile: Displays which pressure profile is currently selected.
Volume read-out: Displays real-time fluid volume information during any given dispensing cycle
(Manual, Auto and Rinse).
Pressure read-out: Displays current pressure in the module.
Tip: When the module is in setup mode (no heaters, main switch in the left position), the pressure read-
out will accurately indicate your water supply pressure. *boilers must be below 70°C or 150°F

Back button: Wherever you see the back button it will take you to the previous screen.
Active profile: This is the profile that is active and is used when the espresso tap lever is positioned to
the Automatic brewing position, indicated by the blue filled circle.
Inactive profile: These profiles are present and contain profile data, but are not currently activated,
indicated by the gray filled circle.
Empty profile: These are empty profile slots and may not be used until profiling data is entered. Empty
profiles are indicated by a non-filled circle.
Profile select: Pressing profile select will set the current cursor selected profile to the active profile.
Profile edit: Press the profile edit button to edit the profile data for the current cursor selected profile.
Cursor select: The dotted outline cursor select indicates which profile is selected on screen. You may
use the rotary encoder or up/down function of the joystick to navigate the profiles list. Pressing the
pushbutton will activate a selected profile.
Tip: When selecting a profile, this menu is also duplicated on the tap display. Depending the installed
distance between the module and tap, it is possible to navigate the menu from the tap screen and scroll
through the profiles using the encoder button. Pressing the center encoder button selects the profile
highlighted on the tap. The center encoder button also navigates to the profile selection menu from the
home screen.

The pressure profiling capability of the Modbar espresso system can be programmed in “simple” or
“advanced” modes, each of which have their own settings screen. It is important to understand the
variables, their definitions, and how they work together to design successful profiles that provide
desirable extraction characteristics.
The system is quite extensive and is capable of simulating almost any espresso machine or pressure
condition available on the market today.
Study of the following reference guide will allow you to successfully use the simple and advanced
programming menu interfaces that follow:

Machine name: This is a descriptive name for the module, touch the name to highlight the field, use the
encoder wheel and push-button to rename the machine if desired.
Line volume: This value is used to accommodate for water in the line between the espresso module and
the espresso tap. It may also be used to account for water loss to absorption by the coffee puck.
The line volume setting may also be used to correct discrepancies between two different espresso
modules that are using the same brewing profile and/or volumetric setting. For example, if two
espresso modules are both programmed to dispense 36 mL and one of them dispenses slightly more
than the other, the line-volume setting may be increased on the overproducing module to adjust the
output accordingly.
Lever operation mode: Use this setting to control the behavior of the lever actuator on the espresso
tap. “Auto and Manual” allows for the use of both automatic pressure profiling mode and manual
operation mode. “Auto” limits the function to only automatic pressure profiling mode. “Manual” limits
the function to only manual operation mode.
Factory reset: This will return all of the system settings to their original factory values. ATTENTION!
You will lose all stored pressure profiles and other settings. A confirmation screen is presented to
confirm the operation of Factory Reset.
Lighting: This button navigates to the lighting settings screen.
Advance preferences page 2: This button will navigate to page 2 of the advanced preferences screen
Save & Exit: You guessed it! This button saves the settings changes and exits the current screen.

Temperature mode button: This button will toggle between Automatic and Manual temperature
modes.
Automatic temperature mode is calibrated at the factory to deliver the best temperature
performance using a single temperature setting.
Manual temperature mode gives you independent control over the set points of each
temperature zone from the home screen: Inlet boiler, outlet boiler, and brew head. At the
home screen, pressing the Heat Zone button will allow you to cycle through each zone and
set its temperature independently.
Rinse Time: The rinse time value controls the number of seconds of the rinse cycle, and can be modified
for a shorter or longer rinse cycle.
Rinse Power: The rinse power value controls the motor speed percentage during the rinse cycle. This
can be modified for a more powerful or less powerful rinse.
