Home Display
When the boiler is operating normally, the controller will
display the Home display. See Fig. D5-2.
The screen display area has three sections:
• The upper section of this screen displays the most
important operating information for the unit. In the
example shown here, the display is showing the sys-
tem setpoint, the operating temperature, the outlet
and inlet temperatures for the water entering and
leaving the boiler, and the outdoor temperature.
(Note that the five lines at the top of the screen are
customizable, and may be arranged differently on
your system.)
• The central section shows some additional operating
and setup information. In this case, this area lists
the boiler name, boiler state, current demand, and
the current password level (the “access status”).
• The lower section shows any current lockouts, holds,
or alerts.
Info/Install Display
From the Home display shown in Fig. D5-2, press the “I”
button (“Info/ Install”). The display will change to show
the six sub-menus available. See Fig. D5-3.
• To move from one choice to another, use the Left-
and Right-Arrow buttons or the Up- and Down-Arrow
buttons.
• Once you have highlighted the choice you want,
press the round OK button.
Table D5-2 shows the functions listed under each of the
sub-menus.
