USING YOUR MICROSENTRY™ REFRIGERATOR CONTROL
During initial startup, or anytime power is interrupted, there will
be an approximate 5 minute delay before the refrigerator starts.
During this period the controller will be assessing the tempera-
ture in the refrigerator and the display will appear erratic, this is
normal. The desired temperature set point can be programmed
during this start up period.
Starting your refrigerator
The refrigerator will begin start up when initially plugged in or
when power resumes after a power outage. At this time the re-
frigerator will take approximately 5 minutes to begin running as
noted above. If the refrigerator has been turned off during use,
“OFF” will appear on the display. To start the refrigerator from
the “OFF” position press and hold the ON/OFF button for three
seconds.
Set temperature
To set temperature set point, press and continue to hold “SET”
button. After one second, set point will be displayed. While
holding “SET” button use the “WARMER” or “COLDER” button to
desired set point.
NOTE: Momentarily pressing & releasing “SET” button will access
information menu of control. Refer to appendix A for information
on this feature.
Refrigerator operation
The available temperature range of the refrigerator is 1° to 7° C.
It may take up to 24 hours for your refrigerator to reach desired
temperature. This will depend on amount of contents loaded
and number of openings and closings of the door.
For best results allow refrigerator to “pull down” to desired set
point before loading. Once contents are loaded, allow at least
48 hours for temperature to stabilize before making any adjust-
ments to the set point.
Alarms
Your MicroSentry™ refrigerator control will monitor refrigerator
function and alert you with a series of audible and visual alarms.
• 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 Alarm: If your
unit reaches an unacceptable temperature
outside of your set point, 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 5.5°C above
the set point and “Lo” indicates that the temperature is 5.5°C
below the set point. The alarm will remain active until the condi-
tion is corrected.
NOTE: During initial appliance start-up, the high temperature
alarm may sound until the interior temperature reaches set
point.
