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.
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.
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 see page 45
and the Heater Status Menu information on page 54.
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 element operation.
Heating elements icon for a water heater equipped with 1 Bank of heating elements.
Each circle represents 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 represents 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 represents 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 represents one heating element. Each diagonal row of 3 elements = 1 Bank
of elements. Filled circles represent 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 represents 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.
Heating elements icon for a water heater equipped with 3 Banks of heating elements. In
this example 2 Banks (6 elements) have been energized and 3 elements have not. The
control system is sensing electrical current from 4 heating elements. The control system
is reporting that it is not sensing electrical current from 2 elements that it should be
sensing current from. The control system would declare an Alert Condition in this case.
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.
