Electronic Demand Timer Features & Options
WATER METER:
The water meter, consisting of a turbine, turbine
mounting assembly, and the sensor housing, is lo-
cated at the valve outlet port. As water passes
through and spins the turbine, two magnets (in the
turbine) cause a back--and--forth movement of a
switch in the sensor housing. This switch movement
sends a pulse to the electronic demand timer.
ELECTRONIC DEMAND TIMER:
The demand timer is actually a small computer. As
it receives pulses from the water meter, it converts
them to gallons of water passing through the water
softener. It multiplies this water usage information
times the water hardness (preprogrammed into tim-
er) to continually calculate the soft water capacity re-
quired. The computer adjusts daily to water using
habits, seeking to supply soft water for the longest
time, using the least (and most efficient) amount of
salt and water to regenerate.
When the computer determines more capacity is
needed, at the next regeneration starting time (2:00
a.m., or as otherwise preset), it will schedule a re-
generation.
