[F30] Storing of accumulated flow
The default setting is not to store the accumulated flow when the power supply is turned off.
This function enables the accumulated flow value to be stored in permanent memory every 2 or 5 minutes.
The maximum writable limit of the memory device is 1 million cycles, which should be taken into
consideration.
If the product is operated 24 hours per day, the maximum writable limit will be as follows:
Data memorized every 5 minutes --- 5 minutes x 1 million cycles = 5 million minutes = 9.5 years
Data memorized every 2 minutes --- 2 minutes x 1 million cycles = 2 million minutes = 3.8 years

: Data memorization is performed every 2 or 5 minutes (depending upon the setting chosen), this means that the accumulated flow
value for up to 2 or 5 minutes before the power supply is turned off will not be added to the device memory.
When the power supply is turned on again, the accumulated flow count will start from the value recorded
at B.
