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
configuration key should never be replaced unless
directed by Technical Support.
• 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
(page 48).
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.
