8.C The Home Display
When the boiler is operating normally, the controller will
display the Home display. See Figure 21.
Figure 21. - Home Display
The Home Display has three sections:
• The upper section (customizable) displays the most
important operating information for the unit. In the
example shown here, the display is showing the system
setpoint, the operating temperature, the outlet and inlet
temperatures for the water entering and leaving the
boiler, and the outdoor temperature.
• 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.
8.D Customizing your Home Display
To customize the upper section of your Home Display
• Press “I” Info/Install button
• Scroll to highlight “Display Setup”, press OK
• Highlight the line you would like to change,(example

Repeat this step for the other parameters, if desired.
