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 44).
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.
