7.2 Navigating the User Interface
Navigating into the Display area menus is as easy as it looks.
The Info/Install button will be the primary button that you
will use to start, and the OK button is what you press to select
and approve the parameters that you have set on the Display.
The arrow keys are for moving up and down, left and right
within the menus. The Back button gets you back to the
previous screen. And the Home button gets you back to the
Home Display.
See Table 10 for more details.
7.3 The Home Display
When the boiler is operating normally, the controller will
display the Home display. See Fig. 27.
Fig. 27 - 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.
7.4 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
”Line 2 Operating Temp”), press OK
• Scroll to highlight the parameter that you do want
displayed and then press OK. The new parameter is now
displayed on the Home Display.
Repeat this step for the other parameters, if desired.
7.5 Entering/Changing Control Settings
Info/Install Display
The Info/Install Display is where you will start every time.
All of your Controls, Diagnostics, Setups, and more, are
accessed starting with the Info/Display screen.
• From the Home display shown in Fig. 27, press the “I”
button (“Info/ Install”). The display will change to show the
six sub-menus available. See Fig. 28.
Fig. 28 - Info/ Install Display
• 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
Table 11 shows the functions listed under each of the sub-
menus. For details, see Sections 8A and 8C.
Changing a Value
The procedure for changing a control value used by the
system is listed below. (In this example, we will use the
screen for the CH Setpoint.)
• Use the Up- and Down-Arrow buttons to step down
through the list until you have highlighted the correct line
on the display.
• Press the round OK button to select that line. Figure 29
shows a typical screen for this type of setting.
