MODULEX CONTROLLER OPERATION

1. INTRODUCTION
The information in this Section provides a guide to the operation of the Modulex Boiler using the E8
Controller mounted on the front of the unit. It is imperative that the initial startup of this unit be
performed by factory trained personnel. Operation by untrained personnel, prior to the initial startup,
will void the equipment warranty. In addition, the following CAUTIONS and WARNINGS must be
observed at all times:
All initial installation procedures must be completed prior to
attempting to start the unit.
THIS SYSTEM UTILIZES 240 VAC POWER. IT MUST NOT BE
SERVICED BY PERSONNEL WHO ARE NOT FACTORY
CERTIFIEDSERVICETECHNICIANS.
DO NOT ATTEMPT TO DRY-FIRE THE BOILER. STARTING
THE UNIT WITHOUT A FULL WATER LEVEL CAN
SERIOUSLY DAMAGE THE UNIT AND MAY RESULT IN
PERSONAL INJURY OR PROERTY DAMAGE. THIS
SITUATION WILL ALSO VOID ANY EQUIPMENT WARRANTY.
2. E8 CONTROLLER DESCRIPTION
The E8 Controller is housed in a compact enclosure measuring 145 mm x 100 mm. The Controller is
mounted on the front of the Modulex Boiler and contains all of the controls, indicators and displays
necessary to adjust, operate and troubleshoot the Modulex Boiler.
The front of the Controller (Figure 2-1) contains a hinged cover which, when closed, reveals a mult-
function LCD display and a Rotary Knob. When the Controller cover is opened, it provides access to
additional controls and indicators used for installation setup, operation and troubleshooting tests for the
Modulex Boiler. These items are illustrated and described in Figure 2-2 and the Table 2-1.
Figure 2-3 illustrates and describes the type of information provided on the LCD display.

program control of the boiler.
When set to the Manual (10 o’clock) position, a flashing “EMERG –MODE”
message is displayed. Heating Circuit 1 (HC1) pump and the first burner stage are
switched on. Pumps for Heating Circuit 2 (HC2) and Domestic Hot Water (DHW)
will also be switched on if sensors are installed and enabled.
The pump(s) will turn off when the flow temperature reaches the value set for
MAX T-FLOW (in EXPERT/HEAT CIRCUIT 1 menu). The first burner stage will cut
off when the boiler temperature reaches the value set for MAX T-MODUL
(inEXPERT/INSTALLATION menu).

3. CONTROLLER MENUS
The Controller includes an extensive set of software menus which are divided into the following Main
Menu areas:
 DISPLAYMenu
 USER Menu
 TIME PROGRAM Menu
 EXPERT Menu
 EXPERT HS Menu (Not Applicable for Modulex)
 GENERALMenu
Each of these Main Menus includes a group of Sub-Menus as shown in the listing below. Access to the
Menus and Sub-Menus shown in this Table is accomplished by opening the hinged display panel cover
and turning the Rotary Knob on the front panel. Clockwise rotation of the knob sequences through the
menus in the “Top-Down” order. Counterclockwise rotation sequences through the menus in the
“Bottom-Up” order.

The basic procedures for navigating through the Main Menus, Sub-Menus and functions are described
in paragraph 3.1 The items and functions included in each Main Menu and Sub-Menu are briefly
described in paragraphs 3.2 through 3.7.
3.1 BASIC MENU PROCESSING PROCEDURE
In order to change or view displayed settings, the display cover must first be opened. When opened,
the Controller automatically takes you to the display and indicator area.
The basic menu processing procedure is accomplished using the Rotary Knob and the Program Key
shown in Figure 2-2. Following initial startup and one-time entry of the required INSTALLATION menu
items (see paragraph 3.8), perform the following steps to access, view and/or change menu items:
NOTE
The following menu processing steps assume that all required (one-time)
INSTALLATION menu items have already been entered. It should be
noted that whenever the unit is powered down and then powered up
again, the INSTALLATION menu will reappear. When this occurs, the
INSTALLATION menu items DO NOT need to be reentered. Normally,
after entry of the required initial INSTALLATION menu entries, turning
the Rotary Knob clockwise will automatically advance the Controller to
the DISPLAY menu group. All items in this group are “Read Only” and
cannot be changed.
1. When the ON/OFF switch on the front of the boiler is turned ON and the swing-down hinged panel
is opened, INSTALLATION will be displayed. This is the initial INSTALLATION menu and it is
assumed that all entries have already been made.
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
3. To view functions included in the INSTALLATION sub-menu, press the Program Key (Item B in
Figure 2-2). 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. 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.
NOTE
Except for the items included in the DISPLAY Menu and sub-menus, all
other Menu groups and sub-menus contain Read-Write items which can
be viewed or, changed. Also, turning the Rotary Knob counterclockwise,
instead of clockwise will scroll through menu items in reverse order.
6. When in the USER, TIME PROGRAM, EXPERT, or GENERAL Main Menu, virtually all sub-menu
items can be changed if the desired value or condition is not displayed.
7. Turn the Rotary Knob clockwise to display the next menu item in the group.

MODULEX CONTROLLER OPERATION

8. To change the value of a displayed sub-menu function, press the Program Key. The Change LED
(item C in Figure 2-2) will light indicating that the displayed sub-menu function can now be
changed. Turn the Rotary Knob clockwise (increase) or counterclockwise (decrease) to change
displayed value of the sub-menu function.
9. To store the displayed value in the Controller memory, press the Program Key. The LED will go
off.
10. Continue this process to view and/or change sub-menu function values in the various groups.
IMPORTANT
Paragraphs 3.2 through 3.7 which follow include flow-chart illustrations
and tabular listings of all Menu and Sub-Menu functions. However,
descriptions, entry ranges and default values are provided for only the
commonly used functions which are referenced in Section 4, titled
Operating Mode Set-Up & Programming Instructions. These commonly
used functions are shown in Bold Italics in the illustrations and tables
which follow.
Refer to Appendix A for additional information on functions marked “Not
Applicable” in the illustrations and tables provided in paragraphs 3.2
through 3.7.
