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 (32) 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 BREW TIME setting. A second brew can be started only after the brew time plus the DRIP OUT time has elapsed. 4. Brew water temperature is controlled via a WATER TEMPERATURE SENSOR (3) and a HEATING ELEMENT (15) controlled by a TRIAC (17) electronic switch. The element is energized according to the sensed water temperature and the BREW TEMP setting. An over-temperature condition will trip the HI-LIMIT THERMOSTAT (4), de-energizing the heating element. Note: On 120 volt units, hi-limit will automatically reset once the tank has cooled by approximately 30.F. On 240 volt units and dual voltage units, the hi-limit must be manually reset by pressing the red button after the unit cools. 5. Individual WARMER PLATES (27) are heated by WARMER ELEMENTS (28), which are controlled by the WARMER keys. Pressing a warmer key will turn ON or OFF the corresponding warmer and LED. MAIN WARMER PLATE is turned ON automatically at the start of a brew cycle. Because coffee loses its freshness after sitting on a warmer, a quality time function is included. The WARMER LEDS will begin to flash some time after the last brew cycle, based on the QUALITY TIME setting. Note: QUALITY TIMER does not turn off the warmer elements. 6. The unit will revert to the energy-saver mode some time after the last brew, based on AFTER HOURS TIME setting.
