PROGRAMMING (continued) 7. Automatic Start-Up in Previous Mode: If the brewer automatic timer is OFF (the factory setting) and power is disconnected, the brewer will start up when power is restored, in the mode it had been in prior to the power disconnection. If the Satellite Brewer has the timer setting ON and power is disconnected, the brewer will start up in the mode that it should be in at the time the power is restored. 8. Brew Volume: The Brewer can have up to 3 different brew volumes on each side.
PROGRAMMING (continued) The factory programming has the After Hours™ mode turned OFF. While in the After Hours mode, the POWER LED will flash continuously. 12. After Hours™: The After Hours™ can be programmed to come on from 1 to 6 hours after the last brew. When the brewer goes into the After Hours™ mode, the water in the tank will be allowed to drop from the normal brewing temperature and will reheat less frequently – this feature saves energy and extend component life.
