INTRODUCTION

The brewer incorporates a wireless interface system that allows the DBC Grinder to load certain information into the "programming chip" located inside the handle of the funnel. This information includes what ﬂavor of coffee is being ground and what batch size will be brewed (small, medium, or large). Once the correct ﬂavor name and amount of coffee is ground, the funnel is loaded into the brewer. The information from the funnel handle is then transferred into the brewer. The brewer then takes this information and dispenses the amount of water preset in the brewer for that particular ﬂavor of coffee and batch size. The brewer can also be programmed to adjust different functions of the brewing process, such as brew temperature, brew volumes, bypass percentages, pulse brew, etc. This allows the operator to program a certain "recipe" for each coffee ﬂavor to be brewed.

GLOSSARY

AD CARD: An assembly consisting of a computer chip (TAG) and an instruction label. Used for loading advertis-

ing messages into the brewer.

BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature

programmed into the brewer.

BYPASS: The process of diverting a portion of the brew water to the outside of the paper ﬁlter so that it does

not pass through the coffee grounds. This process is sometimes used to optimize the ﬂavor of the ﬁnished brew.

CHIP: A computer chip containing either recipes for speciﬁc coffee ﬂavors or advertising messages which are

read by the sensing coils on the brewer. One chip is embedded in each Smart Funnel handle to carry the coffee ﬂavor name and batch size ground from the grinder to the brewer.

CYCLE TIME: The total length of time to complete a brew cycle. Does not include Drip Time. DRIP TIME: The length of time from when the water spray over the grounds ends, to the time that no water drips

from the funnel tip.

FACTORY DEFAULTS: The factory preset brew settings that were installed into the brewer's memory. FIRST ON-TIME: During a pulse brew or preinfusion, this is the time set for the initial ﬂow of water over the

grounds.

FUNNEL DETECT: Sets the inability to initiate a brew cycle if the funnel is not properly inserted into the funnel

rails.

FUNNEL DETECT: Sets the inability to initiate a brew cycle if the funnel is not properly inserted into the funnel

rails.

FUNNEL SENSING COIL: A sensor on the front hood of the brewer, which reads what name and batch size of

coffee was ground into the funnel and allows for the brewer to automatically set itself to what is read from the funnel handle.

INITIAL ON-TIME: During a pulse brew, this is the time set for the initial ﬂow of water over the grounds. LAST ON-TIME: During a pulse brew, this is the time set for the second on-time, and each alternating on-time

for the remainder of the brew cycle.

MAIN SCREEN: The term used to describe the screen that is displayed when the brewer is not in use. This screen

is also displayed after exiting the programming mode.

NO-NAME COFFEE: The term for the recipe used by the brewer when there is no coffee name stored in the funnel.

The brewer can contain separate No-Name recipes for the left and right brewing positions.

OFF-TIME: During a pulse brew or preinfusion, this is the time set for the length of time that the water is not

spraying over the grounds.

PREINFUSION: The process of beginning a brewing cycle with an initial spray of water onto the grounds followed

by a pause in the spray. After the programmed pause, the spray continues without interruption until the end of the brewing cycle.

PULSE BREW: The process which allows the brew water to start, then stop, repeatedly, over the grounds in order

to derive the best ﬂavor from the coffee. Pulse brew is also used in some instances to prevent a funnel overﬂow.

RECIPE: Set of brewing parameters stored in the brewer. The parameters are unique for each coffee name and

include brew ounces, pulse brew, percent bypass, preinfusion and drip time.

RECIPE CARD: An assembly consisting of a computer chip (TAG) and an instruction label. Used for loading a

recipe into the brewer and the companion BrewWISE Grinder.

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, bypass percentages, etc. This allows for the precise brewing of various ﬂavors of coffee. Programming of the brewer is achieved by entering a certain function. Then, by the use of hidden programming 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.

PROGRAMMING THE BREWER (cont.)

RECIPE PROGRAMING METHODS

There are three methods of programming the various brewing parameters of the SINGLE/GPR DBC or DUAL/GPR DBC with Smart Funnel Brewer.

METHOD 1:

Using a Smart Funnel and a G9-2T DBC or MHG Grinder:

Certain coffee NAMES are stored in the G9-2T DBC or MHG's memory. When a particular name of coffee is ground into the Smart Funnel, that name and the batch size selected are transferred from the grinder to the programming chip located in the funnel's handle. The funnel is then inserted into the brewer's funnel rails (left side for DUAL brewers). The sensor coil on the brewer reads the information contained in the handle. This then allows the operator to set the BREW

VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES and DRIP-OUT TIMES

for that particular coffee NAME. Each coffee NAME can be set individually to provide optimum brewing quality.

RECIPES

This diagram allows for the creating, modifying, or viewing of recipes in the brewer.

METHOD 2:

Using a RECIPE CARD to enter all of the brew settings at one time:

If using a coffee name not in the grinder's memory, the customer can obtain a RECIPE CARD from the factory with all the information needed to set up that particular coffee name. This includes the COFFEE

NAME, BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES, and DRIP-OUT TIMES.

METHOD 3:

Not using a Smart Funnel and/or a G9-2T DBC or MHG Grinder:

This allows the operator to enter ONE set of brewing parameters (for each side on DUAL brewers), in the event a Smart Funnel and/or a G9-2T DBC or MHG is not used with the SINGLE/DUAL/GPR Brewer. This is referred to as a NO NAME coffee ﬂavor. If the brewer does not read the information in the funnel's handle, it automatically selects the NO NAME brewing parameters set up prior to brewing. This includes

BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES and DRIP-OUT TIMES for the three batch sizes.

SET NEW RECIPE Using a Smart Funnel and a G9-2T DBC or MHG Grinder: This function allows the operator to set BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, and DRIP-OUT TIMES for each coffee name

preset in the grinder's memory. Certain coffee NAMES are stored in the Grinder's memory. When a particular name of coffee is ground into the Smart Funnel, that name and the batch size selected are transferred from the grinder to the programming chip located in the funnel handle. The funnel is then inserted into the brewer's funnel rails (left side on DUAL brewers). The sensor coil on the brewer reads the information contained in the handle. The name of the coffee ﬂavor will then appear on the display. This then allows the operator to set the BREW

VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, and DRIP-OUT TIMES for that particular coffee NAME. It also allows the operator to set other brewing parameters, such as BREW TEMPERATURE, READY TEMPERATURE, BREW LOCKOUTS, etc. Each coffee NAME can be set individually to provide optimum

brewing quality.

PROGRAMMING THE BREWER (cont.)

SET NEW RECIPES (cont.) SET NEW RECIPE: If not using a Smart Funnel (with a computer chip) and/or a G9-2T DBC or MHG Grinder, the brewer will function as a standard Bunn Single/Dual Brewer:

It is possible to operate the brewer without using a Smart Funnel and/or a G9-2T DBC or MHG Grinder. If a standard funnel, or if a non-DBC grinder is used the brewer will automatically select a NO NAME coffee when the BREW switch is pressed. This means that no name was read from the funnel's handle. There is a NO NAME coffee program that can be set in the SINGLE brewer and two NO NAME coffee programs that can be set in the DUAL brewer which are referred to as NO NAME LEFT and NO NAME RIGHT. The left and right sides of the DUAL brewer can be set up independently of each other. This includes BREW

VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, and DRIP-OUT TIMES. The brewer will perform

in the same capacity as a standard Bunn Single/Dual Brewer. The instructions for programming the NO NAME settings are on the following pages. The same steps are followed for setting the recipe as those that are used to MODIFY A RECIPE, beginning on page 21. Note that on SINGLE brewers, when the display reads NO NAME, that is when MODIFY should be pressed in order to set the parameters for the NO NAME coffee. On DUAL brewers, when the display reads NO NAME LEFT, that is when MODIFY should be pressed in order to set the parameters for the NO NAME LEFT coffee. Otherwise, press NEXT to display NO NAME RIGHT. At this point, MODIFY should be pressed in order to set the parameters for the NO NAME RIGHT coffee.
