| 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 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. |
|
|
|
|
|
|
|
|
|
| Servicing should only be performed by a Qualified Service Agent | |
