HEATER INFORMATION
DESCRIPTION/ACTION DISPLAY
Select Heater Information from the Main Menu and press the
Operational Button under "SELECT" 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.
• Config CRC - A number associated with the configuration
data.
• CCB Version - Software version for central control board.
• UIM Version - Software version for user interface module.
NOTE: Historical data is stored in the CCB's memory. If this CCB
is replaced during servicing the historical data on the CCB being
replaced will be lost. The data stored in the new circuit board 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 raising the Differential
setting to avoid short cycling and excessive component wear,
see Operating Set Point and Differential Adjustment.
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.

function.
