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 rasing 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.
