8.3 TheHomeDisplay
When the boiler is operating normally, the controller will
display the Home display. See Figure 20.
Figure 20. -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.

button (“Info/ Install”). The display will change to show the
six sub-menus available. See Figure 21.
