Selection of Units
and Language
Before using the system, you may wish to change the language used on the screens,
the units used for pressure and temperature, and the date and time format. These
settings will be for the local PC only, and will not affect the display at the SC 255’s in
the system. To change the displayed units, or to select a language for the screens,
choose Store Information from the main menu, then choose Units/Languages. You
will be presented with the Units/Languages screen, which looks like this:
The fields in the screen are these. The selections are self-explanatory.

2 - 1. Navigation and Making Changes
No matter what type of system you are working with, whether refrigeration, HVAC,
or lighting, moving around the screens and menus in an SC 255 is the same. We will
use a series of refrigeration menus and screens as examples in this section, but the
same principles will apply to any other part of an installation.
On the Main Menu, notice that one of the menu items is in reverse video – that
instead of the text being dark on white background, it is white on a dark background.
