  • EC5 Series Features


    Immediate Condition ResponsePush any button and the EC5 wakes up to display the system status with any applicable instructions or messages.

    Power Outage RecoveryIf power is lost during the regeneration process, the EC5 will automatically recover and complete the process once power is restored. This feature ensures that all scheduled regeneration cycles are never missed, and that soft water is always available.

    Instant Informational AlertsThe EC5 provides real-time system status notifications for low salt, loss of power and power restored, service reminders for filter changes, and other useful reminders. These notifications are provided on both the system display as well as the RainSoft Remind® app.

    Redesigned Interactive DisplayThe EC5 provides easy-to-read and understandable system information via a six-line LCD display, which is ideally angled for optimal viewing.

    Energy Efficient ControlA new, redesigned DC power supply uses less electricity than conventional AC power supplies found on other brands of water treatment equipment. There are also fewer moving parts, resulting in increased system reliability and long, trouble-free operation.

    Proportional Brine and RinseOverall system efficiency is achieved with RainSoft’s proportional brining feature. Saves on overall salt and water consumption with shorter regeneration cycles based upon specific household water usage.
