Quality Timer
Coffee looses freshness as it sits on a warmer. The Quality Timer
flashes the warmer lights 30 minutes after the last brew to remind you
that the coffee is nearing the end of its useful life.
After Hours™ Operation
During normal operation, the controller will maintain the precise
brewing temperature. If, however, if the BREW key in not pressed for
3 hours, the brewer goes into After Hours™ mode; any warmer left on
will be turned off; and, the temperature will only be maintained to within
20ºF. This feature prolongs component life and saves energy.
As soon as the BREW key is pressed, the brewer returns to normal
operation, heating the water to the precise temperature before
beginning the brew. The brewer will return to After Hours™ mode only
if three hours pass without a brew being initiated.
Disable/Enable After Hours™ Feature
To disable After Hours™, press the ON/OFF key to turn the brewer
OFF.
Press and hold the CANCEL key until two beeps sound, and the HEAT
indicator flashes twice. This feature is now disabled.
To re-enable After Hours™, press the ON/OFF key to turn the brewer
OFF. Press and hold the CANCEL key until three beeps sound, and the
POWER indicator flashes twice. This feature is now enabled, however,
it will not be activated unless no brew is initiated for three hours.
Over-Temperature and Temperature Fault Protection
Should the water temperature exceed 214ºF (101ºC), or if the controller
does not detect a 2ºF (1ºC) rise in temperature within four minutes of
calling for heat, the brewer will go into Over Temperature Mode; the
heating element is turned off, all warmers are disabled and all lights will
flash.
Possible causes of Over Temperature condition:
• Setpoint is in the boiling range.
• Heating element or temperature probe has malfunctioned.
• Excessive scale buildup is preventing the element from heating the
water.
• Heating element relay fails in the “on” state.
• No water in the tank.
• Hi-limit safety tripped (must be manually reset)
To reset the brewer:
• Determine the cause of the failure and take appropriate remedial
action to rectify the problem.
• Press and hold the CANCEL key for three seconds. Four beeps
will sound and the brewer will resume normal operation.
