Troubleshooting (continued)

WM97+ control fault indications

1. The WM97+ control provides diag-

nostic information for both automatic

reset conditions and manual reset

conditions. See Figure 84, page 74 for

information available on the WM97+

control display and navigation instruc-

tions for all menus.

2. Figure 112 shows the screen behavior

during an automatic or manual reset

condition. The table below the display

illustration lists manual reset condi-

tions and how to reset from them.

3. Figure 113, page 105 lists conditions

that will cause the control to display

a constant red screen. The boiler will

automatically restart if the condition

self-corrects or the technician uses the

WM97+ control’s manual reset screens

to reset.

Make sure to determine the causes of outages. Do not leave the boiler operating without a com-

plete diagnosis.
