General Parameters
General parameters are used by technicians and operators to set control setpoints, defrost schedules, time and date.
Before changing parameters, clear any active alarms by pressing the Alarm Silence button. Press (SET) and hold for five
seconds. If general mode programming has been password protected, you will see PASS on the display. Press (SET) and
use the arrow keys to increment the password number until the correct password is shown, and then press (SET). (If general
parameters are not password protected, PASS will not appear on the display).
The display will show the first programmable parameter: CSP (case temperature set point). The arrow keys may be used to
scroll through the list of general parameters. To change the value of any parameter:
1. Select the parameter using the arrow keys (until the code is shown).
2. Press (SET).
3. The current value of this parameter will be displayed. Use the arrow keys to change the value.
4. Press (SET) to accept value.
5. Repeat steps 1 - 4 until all set points have been properly configured.
6. When finished, press (SET) again for five seconds to save changes and exit. The display will blank for one second and then revert to normal dis-
play if the save was successful.
7. To cancel all changes, press and hold (SILENCE) for five seconds, or leave controller idle for 60 seconds. You will lose all setpoint changes
made since you entered general programming mode.
NOTE: Parameters in General Parameters shaded gray are only shown if the real-time clock module is being used.
