Enter into “program mode” by
pressing the program button,
located in the bottom‐right corner
of the front cover, for 3 seconds
until the LED light turns on.
Important: if power to the valve is

section). After the reset, program
the valve as intended.
Figure 10.
Press and release a desired Brand

The LED light will flash at this time.
When the foam in the cup has
lowered, press and release the
desired brand button. The valve
will begin dispensing and will stop
when the foam or liquid touches
the lever. This is the top‐off pour.
The time between the end of the
initial pour and when the pour is
re‐started is the top‐off delay,
which is now stored in the PC
board. The LED light will be on
steady (no flash) at this time.
When finished, program additional
top‐offs by repeating steps 2 & 3,

The Prism Flavor‐Shot mode is factory programmed with time values that can be useful during initial installation
and for testing the modules. The time values for each portion size are shown in the following table.
Portion Size Initial Pour Setting
Small “S” 1.8 s
Medium “M” 2.8 s
Large “L” 3.8 s
