Reviewing Software Version and
Configuration
The software version, unit configuration number and customer
configuration number are stored in the controller memory. To
view the software version and configuration number, turn the
unit On/Off switch ON:
1.
With the Standard Display showing on the controller (i.e.
setpoint and controlling sensor temperature), press and
hold the ENTER key for 3 seconds.
• Display will show the software version for 2 seconds (in
following format:VERSN 11.71).
• Display then shows the unit configuration number for 2
seconds (replacement controller default setting: CFG U
5000).
• Display then shows the customer configuration number
for 2 seconds (replacement controller default setting:
CFG C 0).
NOTE: The customer configuration MUST also
always be set to the configuration number shown
on the set up decal in the unit control box. Alarm
code 42 (unit configuration alarm) is displayed if
the customer configuration has not been set to a
valid number (other than “0”).

NOTE: The unit will operate and control the con-
tainer temperature if the controller remains pro-
grammed to unit configuration “5000” and cus-
tomer configuration “0”. However, the unit will
not operate customer specific options. See the
decal inside the control box for the correct unit
configuration and customer configuration set-
tings for the unit. To load new configuration
numbers, see MENU GUARD under Menu
Operating Instructions in this chapter.

The display then returns to the Standard Display.
Displaying Alternate Fahrenheit (F) or
Celsius (C) Temperatures
NOTE: The C/F units shown on the controller dis-
play can be changed by pressing and holding the
C/F key, and then pressing the ENTER key.
The controller can display temperatures in Fahrenheit or
Celsius. With the unit On/Off switch ON and the controller
showing a Standard Display:
1.
Press and hold the F/C key. The controller will show the
display temperatures in the alternate temperature scale
(Fahrenheit or Celsius) from the temperatures shown on
the display as long as the F/C key is depressed.
2.
The display then returns to the original display when the
F/C key is released.
NOTE: The setpoint temperature can be entered in
either F or C using the F/C key. Just press and hold
the F/C key (to display the alternate temperature
scale).
