5.1.5 E8 MENU Navigation and Parameter Settings
The selected Menu and Sub-menu are indicated by two black arrows at display bottom pointing
to the Menu and Sub-menu names silk-screened below the display (Figure 5-5).
Following initial startup and one-time entry of the required INSTALLATION menu items (see
Chapter 6, section 6.1), to access, view and/or change menu items follow these instructions:

E8 Controller Menu Navigation Procedure
1. When the ON/OFF switch on the front of the boiler is turned ON and the swing-down hinged
panel is opened, the controller will enter MENU Mode and INSTALLATION will be displayed
(Figure 5-5) in the LCD. This is the initial INSTALLATION menu and it is assumed that all
entries have already been made. See sub-section 4.8 of the E8 Controller User Manual
(GF-115-C) for INSTALLATION menu initial entry information.
2. Turn the Rotary Knob clockwise until the display advances to the DISPLAY menu. The dial
on the clock face will rotate one revolution counterclockwise and then go off. The display
will then show INSTALLATION, which is the first sub-menu in the DISPLAY menu group
(Figure 5-5). The two small black arrows at the bottom of the display will point down to the
menu and submenu names, in this case DISPLAY and INSTALLATION, respectively.
3. To view functions included in the INSTALLATION sub-menu, press the Program Key (Item
E, Figure 5-4). If desired, turn the Rotary Knob to scroll through the functions in the
INSTALLATION sub-menu. As previously mentioned, these display functions are read-only
and cannot be changed. Once you reach the end of the sub-menu, RETURN will appear in
the display.
4. To exit this sub-menu and advance to the next sub-menu in the DISPLAY menu, press the
Program Key while RETURN is displayed. INSTALLATION will again be displayed. Turn the
Rotary Knob clockwise until the next sub-menu is displayed.
5. Repeat steps 2, 3 and 4 to view the remaining main menus and their associated sub-
menus. The remaining main menus are: USER, TIME PROGRAM, EXPERT, EXPERT HS
(Not Applicable to MODULEX), and GENERAL.
