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 five major menu categories which are
applicable to this manual. These categories are
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 levels to
prevent unauthorized use.
Prior to entering the correct password, the
options contained in the Operation, 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 level 1 password (159) is
entered, the options listed in the Setup.
Configuration and Tuning Menus can be viewed
and changed, if desired. The Combustion Cal
Menu is protected by the level 2 password which
is used in Chapter 4 to perform combustion
calibration prior to service use.
