5. Fault and Warning Conditions

This water heater is equipped with electronic controls that have the ability to monitor almost all aspects of the water heater operation. In the case that there is an undesirable or unsafe condition that occurs, the water heater

controls will detect this condition and determine the appropriate action. Part

of this is displaying the information on the LCD in plain text that accurately describes the condition and diagnostics information that can be used to

correct the issue.

There are two types of conditions that can occur during operation. These are Warnings and Faults:

•Warnings: This is a non-safety related condition that the control has detected that may cause the water heater to operate in a less than optimal condition, but does not pose a safety concern.

NOTE: When these conditions occur, continued heating cycles will continue and the heater will attempt to regulate the water in the tank to the Operating Set Point.

Example of a Warning:

•Faults: This is a safety related condition that has been detected by the heater.

NOTE: When these conditions occur, the water heater will not continue any further heating cycles and the water will no longer be heated until the condi- tion is corrected and, in most cases, power has been cycled.

Example of a Fault:

Advanced Diagnostics Information

When a fault or warning has been declared, advanced information can be found in the control. By pressing the Advanced button, detailed information can be found regarding diagnosing and resolving the problem.

WARNING: Usage of the Advanced information requires ability equiva- lent to that of a licensed tradesmen in the field involved.

6. Access to the Current Fault or Warning

When a fault or warning has been detected by the control, it will automatically be displayed on the screen and the back light will blink. If you choose to leave the current fault or warning by pressing the Back key, you can always return to the fault screen through the menu.
