CONTROL PANEL OPERATING PROCEDURES
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.
