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 set temperature 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 the set temperature, press and continue to hold “SET”
button. After one second, set temperature will be displayed.
While holding “SET” button use the “WARMER” or “COLDER”
button to desired set temperature.
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
temperature before loading. Once contents are loaded, allow
at least 48 hours for temperature to stabilize before making any
adjustments to the set temperature.
Alarms
Your MicroSentry™ refrigerator control will monitor refrigerator
function and alert you with a series of audible and visual alarms.
For all alarm and error codes, the alarm LED located in the top
left corner of the display panel will illuminate a steady amber.
For all alarm and error codes except condenser cleaning, an au-
dible alarm will sound, beeping in one (1) second intervals.
• Door Ajar Alarm: If the door has been left
open for over five (5) minutes, the alarm will sound
and the display panel will flash “do.” The alarm will
stop once the door has been closed.
• High and Low Temperature Alarm: If your unit
reaches an unacceptable temperature, above or be-
low your set temperature for too long, the tempera-
ture alarm will sound in one (1) second intervals.
The display panel will flash either “hi” or “Lo” de-
pending upon the condition. “hi” indicates a high temperature
alarm, and “Lo” indicates a low temperature alarm. How far
the temperature must deviate above or below set temperature,
and for how long the temperature must remain there before the
temperature alarm is triggered is fully customizable. See Appen-
dix A for details on how to configure the alarm.
• Temperature Sensor Fault: If the control
detects that the temperature sensor is not properly
functioning, an audible alarm will sound, and “E1”
will flash on the display. Please call AGA MARVEL customer ser-
vice or your dealer if this error code is displayed.
• Condenser Needs Cleaning: When the refrig-
erator has reached the recommended amount of run
time for a condenser cleaning, “cL” will flash on the
display as a reminder to clean the condenser. No audible alarm
is associated with the condenser clean warning. To clear the
alarm:
1) Press and quickly release the SET key 7 times.
“cnd” will be displayed on the screen.
2) While “cnd” is displayed, press and hold the SET key.
The display will show the number of weeks the con-
denser has been operating.
3) Continue to hold the SET key, then press and release the
ON/OFF key. The number shown on the display will be
reset to 00.
4) Release the SET key.
5) The display will return to normal operation after a few
seconds with no key presses.
