Control Features
Pre-infusion:
Controls the initial coffee grounds wetting and the first dwell time after the initial wetting. Pulse
brews are the series of pulses after the Pre-infusion process.
Brew Countdown Timer:
After the start of a brew the LCD display will countdown the remaining time left in
the brew process. The countdown will include all OFF periods programmed in the Pre-infusion and the pulses.
Energy Savings Mode:
If enabled, when the brewer is idle for a selectable time of 1-12 hours, this feature will
allow the water tank to lower its holding temperature to 60°C (140°F). The display will scroll through background
images while in this mode. To exit energy savings mode, press the display and the unit will start reheating to
brewing temperature.
