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)
or the cycle duration is short (divide Burner on Time 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 49.
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.
Servicing should only be performed by a Qualified Service Agent
