2. Diagnostics Menu
Access to diagnostic menu is gained by pressing and holding the up/down arrows and
the "ENTER" button together for three seconds. Scroll through menu options using the
"ENTER" button. Change options using up/down arrows. Reset alarm conditions using
the RESET button. To exit, press the "ENTER" button until normal display returns. To exit
diagnostic menu at any point in the menu, press and hold the "ENTER" button for three
seconds. Diagnostic menu will remain on display for 10 minutes after the last keystroke,
then automatically revert to normal operation mode (cabinet temperature display). All
information given in degrees will automatically convert to the appropriate programmed
scale (°F or °C).

4 16
Right two digits represent compressor run time in last 4 hours to the nearest hour. Example: 16 hours total
run time in the last 4 hours. Value is every 4 hours.
run time in the last 4 hours. Value is every 4 hours.
5 50
Right two digits represent compressor on time percentage for the last 5 run cycles. A run cycle begins when
the compressor switches from off to on and ends the next time it switches from off to on. (See diagram
below). Example: 50% run time over the last 5 run cycles.
Value is calculated as follows: Percent on time = On time last 5 cycles/total time last 5 cycles. Value is
saved every 5 cycles.
Note: "On time last 5 cycles" does not include an on time that was terminated by a defrost cycle or the first
on time after a defrost, and "Total time last 5 cycles" does not include an on or off time that was terminated
by a defrost cycle, the time spent in defrost or the first on time after a defrost.

Right two digits represent compressor run time for the last run cycle. Example: 45 minutes of compressor
run time in last run cycle.

7 45
(Freezer
Only)
Right two digits represent length of time for the last defrost cycle in minutes. Example: 45 minutes in last
defrost cycle.

8 67
Right two digits represent highest temperature recorded during the last high temperature alarm. Example:
Temperature reached 67 degrees during last high temperature alarm. Display will show "8--" if there has not
been a high temperature alarm. Value is saved every 8.5 minutes when in alarm.
Temperature reached 67 degrees during last high temperature alarm. Display will show "8--" if there has not
been a high temperature alarm. Value is saved every 8.5 minutes when in alarm.
9-10
Right three places represent lowest temperature recorded during the last low temperature alarm. Example:
Temperature reached -10 degrees during the last low temperature alarm. Display will show "9--" if there has
not been a low temperature alarm. Value is saved every 8.5 minutes when in alarm.
Temperature reached -10 degrees during the last low temperature alarm. Display will show "9--" if there has
