Abstract
A process is provided for controlling the recharging of a water conditioner. Water usage during selected fractions of a predetermined period of time is sensed. Information signifying the water usage during the selected fractions is stored. A time fraction is automatically determined, based on the stored information, when water is unlikely to be used. A selected parameter, such as volume of water used since recharging, is sensed to determine if recharging is required. The water conditioner is recharged during the automatically determined time fraction if the selected parameter indicates that recharging is required.
