MICROSENTRY™ REFRIGERATION MONITOR
Warning Alarms
Your beverage center has been fitted with a MicroSentry™
refrigeration monitor. This monitor will let you know if your
cellar is not functioning properly for optimum wine and
beverage storage.
Door Ajar Alarm
If the door has been left open for over five (5) minutes, the
alarm will sound in one (1) second intervals. The display
panel will flash “Do” and the LED light will be a steady
amber color. This will stop as soon as the door is closed.
High and Low Temperature
If your unit reaches an unacceptable temperature outside
of your set point for more than one (1) hour, the alarm will
sound in one (1) second intervals. The display panel will
flash either “Hi” or “Lo” depending upon the condition and
the LED light will be a steady amber color. “Hi” indicates
that the temperature is 10 degrees F above the set point
and “Lo” indicates that the temperature is 10 degrees F
below the set point. These alarms will warn you that your
wines have seen temperatures that may not be conducive
for long term storage. The alarm will remain active until
the condition is corrected.
NOTE: During initial appliance start-up, the high tem-
perature alarm may sound until the interior temperature
reaches set point.
Alarm Codes
The control monitors and stores select unit parameters
and will display error codes with sound each time a fault
is detected. See reference below for a description of each
