Legacy View is a free iPhone app developed by Chandler Systems Incorporated. This app is designed to make setting up and monitoring Chandler Systems water treatment systems easier than ever. It covers systems sold under Chandler Systems' three brands (CSI, Clearion, and WaterSoft) that use the Legacy View Valve.

With Legacy View, users can conveniently view all valve settings and status, easily change valve settings, and view current water usage information. The app also allows users to graphically view water usage information and start a regeneration or backwash cycle directly from their phone or tablet. Users can also set and view the servicing water treatment dealer information, providing a comprehensive understanding of the system's functionality and purpose.

Legacy View enables users to connect to all valves in their system from one device, making it a convenient and centralized solution. Additionally, the app allows users to update firmware on Bluetooth LE valves and manage their connection to the valves.

Please note that Legacy View is only compatible with Chandler Systems valves with a revision number greater or equal to "C2.00". These valves utilize Bluetooth 4.0+ (Bluetooth LE) technology for communication and require smartphones or tablets with Bluetooth LE capability. Most recent Apple devices are Bluetooth LE compatible. Users are advised to check their device specifications for compatibility.
