Abstract
A circuit for controlling the regeneration cycle of a water softener includes a flow meter which provides a pulse output of a frequency proportional to the flow rate of the water treated by the softener. A predetermined counter, responsive to the flow meter pulse output, provides a first enabling output when a first count is reached indicating that the capacity for treating a normal 24 hour supply of water remains and provides a second enabling output when a second count is reached indicating that the capacity for treating water has been depleted. A 24 hour timer is responsive to the first enabling output to provide a regeneration timer with a regeneration initiation signal at a preselected time during the 24 hour period following the first enabling output. The regeneration timer is directly responsive to the predetermined counter for initiation of regeneration immediately upon receipt of the second enabling signal.
