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.
