The RainSoft EC5-100 CAB Water Conditioning System with RainSoft Remind® Wireless App Monitoring. 

The RainSoft EC5-30 CAB water conditioning softener system incorporates a redesigned control enclosure and simplified, intuitive interface. 
The RainSoft Remind®, app is available for both iOS and Android platforms. It lets you monitor your EC5 CAB system remotely, alerting you when your system needs salt or requires attention. You can even schedule a service call right from your smart phone or tablet. 
Energy Efficient Control 
The control operates with 24V DC power for safety and efficiency. A DC motor, couple with our patented rotary position sensor, provides quick and accurate valve positioning with less movement than other drive systems, resulting in longer seal life and reduced wear and tear. 
EC5 CAB Features 
Immediate Condition Response 
Push any button and the EC5 CAB wakes up to display the system status with any applicable instructions or messages. 
Power Outage Recovery 
If power is lost during the regeneration process, the EC5 CAB 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 Alerts 
The EC5 CAB 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 display as well as the RainSoft Remind® app. 
Proportional Brine and Rinse 
Overall 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. 
Redesigned Interactive Display 
The EC5 CAB provides easy-to-read and understandable system information via a six-line LCD display, which is ideally angled for optimal viewing.

EC5 CAB - water conditioning with high flow capability 

How the EC5 CAB Water Conditioner Works 
Step 1 
Water enters RainSoft's exclusive rugged EC5 CAB control valve and flows down through the conditioning resin where calcium, magnesium, and other positively charged ions are removed. 
Step 2 
Once completely conditioned, the water exits the resin tank and flows throughout your home. 
Step 3 
At metered intervals, the unit begins a night time regeneration process. Using salt* as a regenerant, the retained hardness ions are flushed out of the system and down the drain. 
Other Benefits 
Injection molded enclosures fit tightly to protect control components from outside elements. 
The cabinet is equipped with an overflow protection system to protect against overflow due to power outages during regeneration. 
The EC5 CAB water conditioner provides detailed system status and operational information through both the control screen, and the RainSoft Remind® app. 
Note that the RainSoft Remind® app is not required to take advantage of these features. 
Operating Features 
A six-line LCD display prompts the user with easy to understand system information and messages. 
Full menu of settings allows you to customize the system to your family's specific water usage. 
Computer control prevents you from running out of treated water. 
Control automatically compensates and adjusts for daylight savings time. 
The system maintains time up to 3 days without a battery backup in case of a power outage. Program settings are maintained indefinitely, eliminating the need to reprogram. When connected to the internet via your home network, the correct time of the day is automatically maintained. 
Calculates and uses optimum salt and water combination for each regeneration. 
* Potassium chloride may be used instead of salt as a regenerant.
