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 steam 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.
●The module will begin to fill the boiler. Once the maximum fill level is achieved, the
module will cease to fill. When full, the sight glass will be approximately half full of water.
●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.

Boiler heating indicator: The red square indicates that the boiler is being commanded to heat. It is
normal for this to flash on and off during regular operation.
Boiler temperature process value: This is the current value in degrees of the active heat zone (selected
by the heat zone button).
Boiler temperature set value: 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. The units for temperature are selected in the preferences/temperature unit’s
dialogue.
Settings button: This button navigates to the main settings screen.
Machine name & status: Displays the machine name and current status of the steam module.
Pressure unit: Displays the pressure units type (preferences/pressure units)
Boiler pressure read-out: Displays current pressure of the steam boiler, this pressure is relative and
calculated by the boiler process temperature value. No boiler pressure will be present until the process
temperature is above the boiler point of water (212°F / 100°C).

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.
Fill probe sensitivity: This setting is used to adjust the sensitivity of the fill level probe. Increasing the
value will make the probe more sensitive, while decreasing the value will make the probe less sensitive.
While it may be necessary to change the sensitivity value for water with very low tds levels, the need to
adjust this setting is usually indicative of another issue, such as scale deposits on the probe or probe
fitting. This setting should be used as a stopgap measure to maintain functional filling operation of the
system until there is time to perform a detailed diagnosis and/or descaling procedure.
Fill probe reading values: This field displays the current reading from the fill probe, from 0-99% of its
range of reading.
Fill probe filter: This setting is used to average a number of samples from the fill probe to avoid false
readings. The setting shown is averaging 100 samples.
Factory reset: This will return all of the system settings to their original factory values. A confirmation
screen is presented to confirm the operation of Factory Reset.
Lighting: This button navigates to the lighting settings screen.
Save & Exit: You guessed it! This button saves the settings changes and exits the current screen.

Fill button: In the event that the fill probe is not correctly causing the boiler to fill, this will allow you to
manually fill the boiler until service can be performed to correct the problem. This button will fill the
boiler while it is pressed and held. Release the button once the water fills approximately half of the sight
glass.

The Modbar steam tap is operated via a lever handle located on top of the tap. This handle actuates a
valve that allows steam to pass through the steam wand.
To dispense steam, move the lever handle from the closed position to the open position. If desired,
steam velocity can be metered by moving the handle only slightly into the open position.
Note: Use caution when operating the steam tap. Steam is hot, and will burn you if it is used
incorrectly. While we’ve taken every effort to ensure that the wand stays cool to the touch, the wand
will become hot near the ends during normal use. We recommend only handling the wand near bent
portion on top.
