Brewing State, Warmers, Real-Time-Clock

Brewing State

BREWING DDD K MM:SS HH:MMP

Description – This screen is displayed when a Brew Cycle is in progress. The time remaining in the Brew Cycle is displayed in the lower left-hand corner of the screen (depicted as “MM:SS”). The Brew Key LED will blink in this state. The Main Warmer is automatically activated upon entry into this state. The Brewing parameters of Brew Size, Dilution, Pre-Infusion, Pulse Brew, and Drip Time are utilized in this state. Refer to the Service Mode Descriptions for more information on Brew parameters.

Pressing the Brew Key or the Cancel Key while in the Brewing State will abort the Brew Cycle and revert the system to the Ready State.

Brew Fill Constant Calibration State

Description – The Brew Fill Constant Calibration State is entered from the Heating State or the Ready State by simultaneously pressing the [Down Arrow] Key and the Brew Key. The system will immediately energize the Dump Solenoid (and dispense hot water) for exactly 10 seconds. The required Brew Fill Constant can be verified by dividing the volume of hot water dispensed by 10 thus yielding the actual Brew Fill Constant in ounces per second.

Dilution Fill Constant Calibration State

---

Description – The Dilution Fill Constant Calibration State is entered from the Heating State or the Ready State by simultaneously pressing the [Up Arrow] Key and the Brew Key. The system will immediately energize the Dilution Solenoid (and dispense hot water) for exactly 10 seconds. The required Dilution Fill Constant can be verified by dividing the volume of hot water dispensed by 10 thus yielding the actual Dilution Fill Constant in ounces per second.

Warmers

---

Description – The warmers are generally controlled manually via the Warmer Keys on the keypad. The only situation when this is not the case is during a Brewing Cycle. The Main Warmer is automatically turned ON when the system enters the Brewing State. Each Warmer has an optional timer, power level, audible alarm, and power reduction feature associated with it. The Warmer Timer is particularly useful to indicate when a brew has become stale. Refer to the Service Mode Descriptions for more information on Warmer options.

Real-Time-Clock

---

Description – The Real-Time-Clock (RTC) allows the system to automatically turn ON at a specified time (usually in the morning) and turn OFF at a specified time (usually at night). The RTC also has separate settings for weekdays and weekends. This feature eliminates the wait associated with heating up the reservoir tank every morning. Refer to the Service Mode Descriptions for more information on Real-Time-Clock parameters.
