DBC CONTROLLER
General
This brewer utilizes BUNN® DBC™ technology to control most of its functions. The controller is factory set to
brew in accordance with accepted coffee industry standards, yet may be customized by the owner to achieve a
variety of coffee flavor profiles. All user-accessible features of the controller are viewed and entered using the
display unit. The brewer operating settings are stored in the controller and will remain even in the event of power
failure. Three requirements must be met in order to initiate a brew cycle, (1) Server must be present, (2) Funnel
must be present, (3) Tank must be up to brewing temperature. Attempting to brew when any or all requirements
are not met will result in a non-brew with flashing indicator(s). The display will show what's wrong along with the
appropriate Left Ready or Right Ready indicator flashing. The display will show SEr when server is missing, will
show FUnL when funnel is missing, and will show COLd when tank is not up to temperature. Display will show
any or all of these messages. As they are corrected, that message will disappear. Once requirements are met, it
is necessary to press START again to initiate a brew cycle. Flashing indicators can be cleared by pressing the
STOP button.
The brewer also features funnel locks that prevents removing the funnel until they retract.
Home or FUNC Ø screen
When the unit is first connected, the display will be in the “Home Screen” position where the actual temperature
of the water in the tank is displayed. The display will revert to this screen when its keys have not been pressed for
more than 30 seconds or the “FUNC” key has been held, allowing it to quickly scroll back to this screen. From
this screen all other functions are accessed. The brewer will return to normal operation only after the display is
returned to this position. The “Home Screen” changes from tank temperature to showing time remaining in brew
cycle when a brew cycle has been started. The time remaining is also accompanied by an "L" or "r", showing
which side is brewing. If both sides are brewing the display shows the last one initiated. "+" and "-" can be used
to toggle between L and r.
Moving to any other function screen
Pressing the “FUNC” key once will scroll the display to the next available screen. Each controllable element of the
brewer has a function number assigned to it and that number 1, 2, 3, etc. will be displayed in the upper left hand
corner of the display when you reach that screen. The function number will increase with each press of the
“FUNC” key. To scroll backwards or go to a lesser function number, press and hold the function key, then press
the minus “–“ key. The function number will decrease with each press of the “FUNC” key. NOTE: Pressing the “–
“ key before the “FUNC” key will change the setting of the function. It is important to press and hold the “FUNC”
key before pressing the “–“ key.
In any screen other than home screen, the tank heater and tank refill circuits are disabled. They will
become active again as soon as the display unit returns to the home screen.
Programming- Always refer to Function List
Programming is divided into two sections, "USER" and "SECURED". "USER" Section (Functions 1-18) is accessed
by pressing the FUNC button on the display box and entering the correct password (unless password is "0"). The
"+" and "-" buttons can be used to alter the target values (that are set in the "SECURED" section) by a maximum
amount of ±5%.
Access to the "SECURED" section (Functions 101 and up) is accessed by setting the RUN - PROGRAM switch on
the DBC controller to PROGRAM and then entering the correct password (unless password is "0").
