The "REFRIGERATOR and/or FREEZER"
indicators will illuminate for each model type
as it is selected depending upon the model
configuration. (example: code 436 will only
illuminate the "REFRIGERATOR" indicator
because it is an All Refrigerator)
Setting the model code is required
whenever the low voltage board is
replaced, this will update all of the settings
indicated in Table 1 on Page 35 for the
model you select. With this setting you can
program all necessary settings with one

To exit Mode B and retain any changes
made in system up to this point you
must press and release
"ACTIVATE CONTROLS" one
time, the display changes to

changes were written to the eeprom
and that the system has left Mode B
and returned to Mode A.
The other way to ensure changes
have been written into the eeprom
is to press and hold "ACTIVATE
CONTROLS" for three seconds and
you will get three audible tones along
with a normal temperature display.
This indicates that you have left Mode
B and returned to normal operation .
Failure to do this will cause system
to time out after 10 minutes and any
changes will be lost.
