PROGRAMMING

Using the menu-driven display on the front of the brewer, the operator has the ability to alter or modify various brewing parameters such as brew temperatures, brew volumes, dilution volumes, pulse brew, etc. This allows for the precise brewing of various flavors of tea and coffee.
Programming of the brewer is achieved by entering a certain function. Then, by the use of hidden programming switches and the brew/function switches, the operator can customize the brewing process to their specifications.

PROGRAMMING SWITCHES
To access the programming mode, and to scroll through the different function screens, hidden programming switches are used. There are five of these switches that will be used for the setup of the brewer.

a) Right Programming (hidden) switch (just to the right of the display): This is used to access the programming mode, and is also used to scroll forward through the function list.
b) Left Programming (hidden) switch (just to the left of the display): This is used to scroll backward through the function list.
c) Brew A,B,C (Left Dot, Center Dot, Right Dot – Twins Only): Used to select options that appear on the display during programming.

For more advanced PROGRAMMING information, refer to programming manual at www.bunn.com

The programming of the brewer is divided into four main categories: Recipes, Calibration, Settings, and Service.
The following function screens are in order of appearance. Each screen will have instructions on how to access and the procedures for programming the various functions of the brewer.

IMPORTANT PROGRAMMING NOTES

READ CAREFULLY
To exit the programming mode at any time, press and release either ON/OFF pad located on the front switch panel. The display will return to the MAIN SCREEN.
If none of the five programming switches are pressed within one minute during the setup of the brewer, the programming of the function screen that is being set will be exited and the display will return to the MAIN SCREEN.
Always remember to place a container and funnel under the sprayhead when operating the brewer during the set-up of CALIBRATE FLOW, and testing the brew and bypass valves in SERVICE TOOLS/TEST OUTPUTS.

This screen will be shown when the brewer is ready for use. The screen displays the water temperature in the tank. When the water in the tank reaches the correct set temperature, the display will change from HEATING to READY TO BREW.

PROGRAMMING LOCKOUT SWITCH is located on the main circuit board.
This switch can be set to prevent access to the programming settings of the brewer. Once all the correct brew settings are programmed, the operator can set the switch to the “ON” position to prohibit anyone from changing the settings. With the switch in the “ON” position, the programming menus can still be accessed to view the current settings. However, no changes will be saved.
