CONTROL PANEL OPERATING PROCEDURES
3-5
3.4. OPERATING MENU
The Operating Menu displays a number of key
operating parameters for the unit as listed in
Table 3-2. This menu is “Read-Only” and does
not allow personnel to change or adjust any
other displayed items. Since this menu is “Read-
Only”, it can be viewed at any time without
entering a password. Press the ▲ arrow key to
display the menu items in the order listed (Top-
Down). Pressing the ▼ arrow key will display
the menu items in reverse order (Bottom-Up).
3.5. SETUP MENU
The Setup Menu (Table 3-3) permits the
operator to enter the unit password (159) which
is required to change the menu options. To
prevent unauthorized use, the password will
time-out after 1 hour. Therefore, the correct
password must be reentered when required. In
addition to permitting password entries, the
Setup Menu is also used to enter date and time,
language to be used for display messages, units
of temperature measurements and entries
required for external communication and control
of the unit via the RS-232 port. A view-only
software version display is also provided to
indicate the current Control Box software
version.
NOTE:
The Outdoor Temp display item shown with
an asterisk in Table 3-2 will not be displayed
unless the Outdoor Sensor function has
been enabled in the Configuration Menu
(Table 3-4).
