HEATER INFORMATION
DESCRIPTION/ACTION
Press Heater Information from the Main Menu to enter this menu.
This menu contains non adjustable operational information.
• Elapsed Time - Total accumulated time the control system
(water heater) has been energized.
• Burner On Time - Total accumulated time the control system
has been in the heating operating state; burner run time.
• Total Cycle Count - Total accumulated count of heating
cycles.
• CCB Version - Software version for central control board.
• Config CRC - Verifies the configuration key matches the CCB
programming.
• UIM Version - Software version for user interface module.
• Use External Enable - Enables/Disables the external enable
circuit.
• External Enable Status - Displays whether or not the external
enable circuit has been activated.
• Ignition Trials - Displays the number of ignition trials allowed.
NOTE: Historical data is stored in the configuration key. If this
"key" is replaced during servicing the historical data will be lost.
The data stored in the new configuration key will no longer
reflect the entire history of the water heater.
The Elapsed Time, Burner On Time and Cycle Count indicate
age, usage and wear.
If the Cycle Count per day is high (divide cycle count by days
to determine cycles per day) or the cycle duration is short
(determine burner on time total minutes, divide burner on time
total minutes by cycle count) consider rasing the Differential
setting to avoid short cycling and excessive component wear,
see Operating Set Point And Differential Adjustment on page 39.
This historical data can also be used to assist facilities managers
in forecasting planned replacement of equipment to help avoid
lengthy and costly hot water supply interruptions
