STATUS ICONS
The Status Icons are displayed on the Desktop screen and convey operational and diagnostic information. The icons are described
in the table below. See Figure 59 on page 45 and the Sequence Of Operation on page 57.
TABLE 14
Icon Description
Water temperature in the tank has fallen. Shaded area of the animated thermometer icon will rise and fall in response to
water temperature in the storage tank as sensed from the Upper and Lower Temperature Probes. See beginning on page
8 and Figure 4 on page 9 for location of Temperature Probes.
Water temperature in the tank has reached the Operating Set Point. The control system enters the Standby mode.
The control is unable to initiate a heating cycle. This will happen whenever a Fault condition is detected by the control system
or when the Enable/Disable switch on front panel or Building Management system Enable/Disable circuit is an open circuit.
Display will read "Status: Water Heating Disabled". For more information see Enable/Disable Circuit on page 42.
The Combustion Blower is being energized.
The Blower Prover pressure switch contacts have closed. The check mark icon is visual conrmation of contact closure. See
beginning on page 8 for Blower Prover Switch location.
The Spark Igniter is being energized. See Figure 2 on page 7 for Spark Igniter location.

The 24 Volt Gas Valve is being energized.
The control system has sensed ame at the Main Burner from the ame sensor. See the Sequence Of Operation Flow Chart
on page 58 and Figure 2 on page 7.
The control system has declared a Fault condition and must be inspected/serviced by a Qualied Service Agent. Fault
message details can be viewed in the Current Fault menu. Heating operation is disabled (lock out) until the condition that
caused the Fault is corrected. Power to the water heater must be cycled off and on at the breaker to reset the control system.
NOTE: Cycling power will not reset the control system if the condition that caused the Fault has not been corrected.
The control system has declared an Alert condition and must be inspected/serviced by a Qualied Service Agent. The water
heater will continue to operate during an Alert condition.
