IntelliFresh Function and Features
The IntelliFresh system will alert you when the coffee has exceeded the desired holding time. The Intellifresh system is activated by a connector on the satellite coming into contact with a corresponding connector on the brewer. IntelliFresh is adjustable through the universal control module (UCM) on the brewer.
Quality Timer (factory setting: 2 hours)
Press ¤ to select, press ◄ or ► to choose the desired setting. The timer is intended to notify the user when the coffee loses its freshness. The LED indicator light on the satellite will remain solid red until the quality timer expires.At expiration, the LED will flash and continue flashing at the factory setting for an additional 8 hours. The additional 8 hours is controlled by the Warmer Auto-Off setting.
•Setting Range: 20 to 240 minutes.
•Time Expiration Indicator: The LED flashes after expiration of the quality timer setting for up to a total of 12 hours. The default time is 8 hours
after expiration of the quality timer.
Warmer Auto-Off (factory setting: 10 hours)
Press ¤ to select, press ◄ or ► to adjust from 1 to 12 hours. 
This feature has higher priority than the quality timer. It shuts
off the warmers after a pre-determined time, starting when the
BREW button is pushed. The quality timer does not affect this
function.
Error Codes:
1. Three long blinks and one short blink = heater error. 2. Three long blinks and two short blinks = sensor error
Warmers
The warmers, will turn on automatically whenever a coffee brew cycle is started. The temperature of the warmers are controlled at the warmer buttons on the control panel.
