1. e U-Control provides diagnostic information for
both automatic reset conditions and manual reset
conditions. See Figure117,page106 for informa-
tion available on the U-Control display.
2. Figure 124 shows the screen behavior during an
automatic or manual reset condition. e table
below the display illustration lists manual reset conditions and how
to reset from them.
3. Figure125,page118 lists conditions that will cause the control to dis-
play a constant red screen. e boiler will automatically restart if the
condition self-corrects or the technician uses the U-Control’s manual
reset screens to reset.
Make sure to determine the causes of outages. Do not leave the boiler operating without a complete diagnosis.
