Table 6. 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 ther -
mometer 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.
The control system is in Heating Mode and has energized the electromagnetic contactor coils for at least
one bank of heating elements. 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
operation.
Heating elements icon for a water heater equipped with 1 Bank of heating elements. Each circle repre -
sents one heating element. Each diagonal row of 3 elements = 1 Bank of elements. Open circles represent
heating elements the control system has not energized and is not sensing electrical current from.
Heating elements icon for a water heater equipped with 2 Banks of heating elements. Each circle repre -
sents one heating element. Each diagonal row of 3 elements = 1 Bank of elements. Open circles represent
heating elements the control system has not energized and is not sensing electrical current from.
Heating elements icon for a water heater equipped with 3 Banks of heating elements. Each circle repre -
sents one heating element. Each diagonal row of 3 elements = 1 Bank of elements. Open circles represent
heating elements the control system has not energized and is not sensing electrical current from.
Heating elements icon for a water heater equipped with 3 Banks of heating elements. Each circle repre -

heating elements the control system has energized AND is sensing electrical current from.
Heating elements icon for a water heater equipped with 3 Banks of heating elements. Each circle repre -
sents one heating element. Each diagonal row of 3 elements = 1 Bank of elements. Open circles with an
X represent heating elements the control system has energized that it IS NOT sensing electrical current
from.
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 cor -
rected. 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.
