If the function is turned off the electronics
assembly monitors the flow meter pulses,
recording
one pulse each turn
.
Filter on:
If the function is turned on the electronics

.
“Change water filter” message
The electronics assembly uses the flow meter
impulses to keep track of the amount of water
which has flowed through; after the specified
amount (set in accordance with the water
hardness level), the “Replace filter” message
appears.
