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.
