Abstract:     A system is provided for monitoring the status of a water softener at a remote location. The system includes a water softener controller with a control processing unit for determining the status of the water softener. The system also includes a water softener transmitter and a water softener indicator. The transmitter is coupled to the controller and transmits the status of the water softener to the indicator. The water softener indicator receives and displays the status message. The system is capable of determining whether the water softener is operating normally, whether the salt level is low or whether the water softener needs servicing.
