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 Figure 3 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 circuit is an open circuit. For more information see Enable/Disable Circuit on page 39.

 

 

 

 

 

The Combustion Blower is being energized.

 

 

 

 

 

The Blower Prover pressure switch contacts have closed. The check mark icon is visual confirmation of contact closure. See

 

 

Figure 3 on page 8 for Blower Prover Switch location.

 

 

 

 

 

 

 

 

The Hot Surface Igniter is being energized. See Figure 2 on page 7 for Hot Surface Igniter location.

 

 

 

 

 

The igniter has been energized and the control system has sensed the required minimum igniter current. The check mark

 

 

icon is visual confirmation of minimum igniter current. See the Sequence Of Operation on page 43 for minimum current (AC

 

 

amps) information.

 

 

 

 

 

 

OFF

The 24 VAC Gas Valve is being energized.

GAS ON

The control system has sensed flame at the Main Burner from the flame sensor. See the Sequence Of Operation Flow Chart on page 55 and Figure 2 on page 7.

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 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.
