STATUS ICONS
Status Icons are displayed on the Desktop screen and convey operational and diagnostic information. Icons are described in the table
below. See Figure 40 on Page 36. Ensure the water heater is properly grounded. Flame sensing requires an adequate earth ground. If the
water heater is not properly grounded it will cause Ignition Failure. See Electrical Wiring on Page 33.
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 Features and
Components section starting on page 11 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 (located at the base of the water heater) is in disable position.
The Combustion Blower is being energized.
The Spark Igniter is being energized. See "Spark Igniter" on Page 14 in the Features and Components section.
The 24 Volt Gas Control Valve is being energized.

The control system has sensed flame at the Main Burner from the flame sensor. See the "Sequence Of Operation Flow
Chart" on page 49 and Figures 2 &3 in Features and Components.
The control system has declared a Fault condition and must be inspected/serviced by a Qualified 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 Qualified Service Agent. The water
heater will continue to operate during an Alert condition.
