About this app

Legacy View makes setting up and monitoring your Chandler Systems water treatment system easier than ever! This App covers systems sold under Chandler Systems' three brands (CSI, Clearion and WaterSoft) that use the Legacy View Valve. When used with a Legacy View Valve the user, through the app, can do the following functions:

- Connect to all the Legacy View valves in your system.
- Conveniently view the status of your valve.
- Easily view and change valve settings.
- View current water usage information.
- Graphically view and export water usage information.
- Start a regeneration or backwash cycle from your phone or tablet.
- Set, view, import and export the servicing water treatment dealer information.
- Better understand how your system is working and understand what settings are for.
- Update firmware on the Bluetooth LE valves.


Permissions:
- Access Bluetooth setting, Pair with Bluetooth devices: This app uses your devices Bluetooth radio to communicate with the Legacy View valve.
- Approximate location (network-based): This is a requirement of the Android operating system for the App to scan for Bluetooth devices on Android Marshmallow +.
- Write External Storage: This is a requirement to manage valve firmware, export graph data and import/export dealer information. We do not modify or view anything outside of the “/Documents/Water System” directory, we only export mentioned data to this directory.
- Read External Storage: This is inherited from the write external storage permission. We do not read anything from external storage.

Troubleshooting:
Some users experience difficulty with their valve not showing up on the device list. When this occurs, here are some things to try.
1. Make sure Bluetooth is turned on for your valve. Go into the Advanced menu on the valve by pressing and holding both buttons for 5 seconds until the screen starts flashing. Then press the Menu/Enter button repeatedly until you see "bE 0" or "bE 1". If it is "bE 0", then Bluetooth is turned off, press the Set/Change button to enable it, changing the setting to "bE 1". Then press Menu/Enter button repeatedly until you are back at time of day. If your valve will not set and stay at "bE 1" then contact us, your board may need replaced.
2. Unplug your valve and remove the 9V battery (if installed). Wait 30 seconds, then re-power your valve.
3. Turn Bluetooth on your phone off and then back on.
4. Reboot your phone.
5. Make sure your location permission is turned on for the Legacy View app. Location permission is required by Google to use the Bluetooth LE scanner. We do not need or access your location, but because Bluetooth can be used to determine your location, we have to have the location permission just to do a scan for our valves.

Once you can connect to your valve, make sure that you allow your valve to update firmware if the app prompts you to do a firmware update.

When you go to advanced settings you can't get anything to load on the page. So I click dealer info. - won't load, settings again - wont load, device list & go back in and it still won't load. Then I disconnect Bluetooth, reconnect & still won't load. Then after standing there for 15 minutes and keeping my thumb on the screen so it won't time out all of sudden I can see the resin grain capacity, override days etc. but I can't see any of the other information below. SUPER EFFECTIVE. Ridiculous.

Hello Hillary. I'm sorry to hear that you are having trouble. I assume you are close to your valve when trying to connect? They don't give adequate space to properly reply here, it would be best if you could contact us directly. In the app: go to "Support" (in the left menu) then "Send Feedback", or you can call us at (888) 363-9434 (M-F, 8-5 EDT).

no exit or close app menu item or button to close the app. this is why low rating. it's annoying! i have to lock my phone. unlock my phone. finally select from open apps screen to close it. as a senior app developer, this very easy to do. but some how these morons don't want to put in less than 30 minutes to fix it in an upgrade.

The app overall works, but it would be much better if you could access the app info without being connected to the units. If I walk into a store to purchase salt, I cannot check how much is currently in the tank. it seems it should download the current (most recent) data to the phone. I can't see how much water I've used or anything.

Hi Derek. Thanks for your feedback! The app - valve connection is Bluetooth, which is only a local connection. Your suggestion is interesting, the app would have to connect in the background when your phone is close enough to your valve, and remember the data. This is not an easy change, but we will keep it in mind as we consider future features.
