• Operating Mode: The default setting is the Standard
mode which provides a balance between power
consumption and peak variation performance. 
High Performance mode provides minimum temperature
peak variation.
Note: Customers performing on-site temperature calibration
may observe as much as a 2°C variation when an external
probe is placed next to the freezer control probe. 
This variation is due to optimization of the control system to
ensure temperature uniformity throughout the chamber.
• Power Recovery Delay: Press this button to set the
time delay upon startup after power failure. Default is 0.
• Temperature Offset: This is used for calibration. 
Range is –10°C to +10°C. Default is 0.
• Backup System Settings: This screen allows the user
to select the backup type and backup setpoint for units
with a backup system installed. For more information,
refer Backup System (Optional).

adjusted by swiping the spin control up / down or
pressing the up / down arrows.
Note: A setpoint change may automatically change the warm
and / or cold alarm setpoints as well to prevent unnecessary
alarms.
• After selecting the temperatures, press the Save button
to confirm changes.
Note: If the save button is not pressed, the unit will not
respond to the setpoint change request.
Warm Alarm Test: Clicking this button puts the system into a
warm alarm test which simulates a warm alarm experience.
Once this is selected, the home screen is displayed with the
current temperature readout. The temperature display will
increase to the warm alarm temperature setpoint. Once the
warm alarm temperature is reached, the user is prompted to
end the test.
