3.3. CONTROL PANEL MENUS
The Control Panel incorporates an extensive
menu structure which permits the operator to set
up, and configure the unit. The menu structure
consists of four major menu categories as
shown in Figure 3-2. Each of the menus shown,
contain options which permit operating
parameters to be viewed or changed. The
menus are protected by a password to prevent
unauthorized use.
Prior to entering the correct password, the
options contained in the Operating, Setup,
Configuration and Tuning Menu categories can
be viewed. However, with the exception of
Internal Setpoint Temperature (Configuration
Menu), none of the viewable menu options can
be changed.
Once the valid password (159) is entered, the
options listed in the Setup, Configuration and
Tuning menus can be viewed and changed, if
desired.

plished using the Menu Keys shown in Figure 3-
