Touch the Save tab and press the “Save registry” button. This will store the calibration parameters in memory. If

the upper right corner of the System settings window to close the window and return to System Maintenance.
7.3 Factory Security Options
The factory level of settings are for Cincinnati Sub-Zero personnel and its affiliates. These settings affect
chamber operations and safeties and are not meant for the end user. Any modification of these settings without
written authorization from Cincinnati Sub-Zero will void the chamber warranty.
7.3.1 Setpoint Limits
The setpoint limits restrict the minimum and maximum setpoints for temperature and humidity that can be
entered. These values are set by the factory to the safe operating range of the chamber.
7.3.2 Startup Configuration
The startup configuration settings tell the EZT-550 how to initialize the specific chamber systems that are present
on the chamber. This affects chamber options and control settings relevant to those systems.
