ELECTRONIC CONTROL SYSTEM
Table 1 Status Icons
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
immersion Temperature Probe.
Water temperature in the tank has reached the Operating Set Point. Shaded area of the
animated thermometer icon will rise and fall in response to water temperature in the
storage tank as sensed from the immersion Temperature Probe.
The control is unable to initiate a heating cycle. This will happen whenever a Fault
condition is detected by the control system or when either of the two Enable/Disable
circuits are open circuits. For more information on Enable/Disable circuits review the
Heater Status Menu information on page 63.
The control system is in Heating Mode and has energized the electromagnetic contactor
coils for at least one heating element. This animated icon DOES NOT indicate current
has been sensed from the heating elements, only that there is a call for heat present and
the control system has initiated heating element operation.
Heating element icon for a water heater equipped with 1 heating element. Open circles
represent elements the control system has not energized and IS NOT sensing electrical
current flow from.
Heating element icon for a water heater equipped with 2 heating elements. Each circle
represents one element. Open circles represent elements the control system has not
energized and IS NOT sensing electrical current flow from. Filled circles represent
elements the control system has energized and IS sensing electrical current flow from.
Heating element icon for a water heater equipped with 3 heating elements. Each circle
represents one element. Filled circles represent elements the control system has
energized and IS sensing electrical current flow from.
Heating element icon for a water heater equipped with 4 heating elements. Each circle
represents one element. Open circles with an X represent elements the control system
has energized that it IS NOT sensing electrical current flow from.
Heating element icon for a water heater equipped with 5 heating elements. Each circle
represents one element. Open circles represent elements the control system has not
energized and IS NOT sensing electrical current flow from. Filled circles represent
elements the control system has energized and IS sensing electrical current flow from.
Heating element icon for a water heater equipped with 5 heating elements. In this
example 4 elements have been energized and 1 element has not. The control system IS
sensing electrical current flow from 2 elements. The control system IS NOT sensing
electrical current flow from 2 elements that it should. The control system would declare
an Alert Condition in this case but would continue to operate.
The control has detected/declared a Fault Condition. Fault message details can be
viewed in the Current Fault menu. Heating operation is discontinued (locked 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 has detected/declared an Alert Condition. The water heater will continue to
operate during an Alert Condition but there is an operational condition that requires the
attention of a Qualified Service Agent. Alert message details can be viewed in the
Current Alert menu.
