SEE PAGE 11 FOR COMPONENT NAMES / NUMBERS
1.Pressing the POWER key energizes the unit. The POWER LED will glow whenever the unit is ON.
2.Automatic fill is accomplished via a FILL SOLENOID
(32)and a WATER LEVEL PROBE (7). The probe
senses ground through the water in the tank. When the water level falls below the probe and ground is no longer sensed, the CONTROLLER (20) energizes the fill solenoid until the water level again reaches the water level probe.
3.Pressing the BREW key begins the brew cycle. Pressing the CANCEL key at any time during the
brew cycle terminates the brew. The BREW SOLENOID
(18)is energized by the CONTROLLER (20) for a time determined by the setting of the BREW TIME CONTROL. A second brew can be started only after the brew time plus the time set on the DRIP OUT TIMER has elapsed.
4.Brew water temperature is controlled via a water temperature sensor and a HEATING ELEMENT (15) controlled by a TRIAC (17) electronic switch. The element is energized according to the sensed water temperature and the desired temperature setting of the BREW TEMP control. An
