CHAPTER 3: E8 CONTROLLER OPERATION
The E8 Controller operates in NORMAL Mode when the controller door is closed, which allows
for monitoring the boiler status through the display window and setting the HEATING Mode.
When the door is opened, the unit enters MENU Mode, and in this mode the boiler may be
initialized, configured, and adjusted. The controls and display for the E8 controller are described
in the following sections.
3.1 NORMAL Mode Operation (Door Closed)
When the hinged door is closed on the E8, the unit is in NORMAL Mode.
3.1.1 NORMAL Mode Display Functions
Figure 3-1 describes the types of information provided on the LCD display when in NORMAL
Mode (door closed). Note that the display in the illustration is only an example, and that an E8
Controller in service will show information appropriate for its configuration.
