4. 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 condition is corrected and, in most cases, power has
been cycled.
