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.
Claims19
A process for controlling the recharging of a water conditioner, which comprises the steps of:
- sensing if water is being used during selected fractions of a predetermined period of time;
- storing information signifying water usage during said selected fractions;
- automatically determining a time fraction, based on the stored information, when water is unlikely to be used;
- sensing a selected parameter to determine if recharging is required;
- and
- recharging the water conditioner during said determined time fraction if said selected parameter indicates that recharging is required.
A system for controlling the recharging of a water conditioner, which comprises:
- means for sensing if water is being used during selected fractions of a predetermined period of time;
- means for storing information signifying water usage during said selected fractions;
- means for automatically determining a time fraction, based on the stored information, when water is unlikely to be used;
- means for sensing a selected parameter to determine if recharging is required;
- and
- means for recharging the water conditioner during said determined time fraction if said selected parameter indicates that recharging is required.
