GLOSSARY

AD CARD: An assembly consisting of a computer chip and an instruction label. Used for loading advertising 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 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.

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 and an instruction label. Used for loading a recipe into the brewer and the companion BrewWISE Grinder.

SERVER DETECT: Sets the inability to initiate a brew cycle if the server is not properly placed on the stand below the brew funnel.

SOFT HEAT: The type of server and brewer which are used as part of the Smart Funnel system. The server is placed on the brewer, and is connected through the receptacles on the brewer. The server contains a tem- perature-controlled heater which maintains the coffee at a constant temperature.
