## What is Symphony by WaterFurnace?

Symphony is a WiFi enabled comfort platform that’s unsurpassed in its ease of use, features and capabilities. It provides detailed system feedback in real-time and the tools to control it. Symphony marries the Aurora controls of your WaterFurnace geothermal unit with the Aurora Weblink router, providing access to your equipment from practically anywhere. Symphony is cloud-based so there’s no software to install and provides control over your entire geothermal system - not just the thermostat as in other ‘smart thermostat’ systems.

Symphony allows you to:

•	View and control your geothermal system’s operation from anywhere using a laptop, smart phone or tablet using an intuitive dashboard for quick access to your unit’s status, operation history, alert history, and energy usage.
•	Remotely control temperatures and programs for up to 6 zones (requires the IntelliZone2 zoning system).
•	Observe and track your unit’s energy use for the last 13 months.
•	Provide equipment performance data to dealers for remote monitoring and diagnosis (Premium package required). 
•	Receive equipment alerts and service reminders (as well as your dealer) via email and texts (Premium package required).

### 1/5 — Useless

*2026-04-24, version 3.5.5*

I can’t even log in to the app.

### 2/5 — Extremely basic and not useful

*2026-03-01, version 3.5.5*

This app is extremely basic and not useful. You can’t change anything except the temperature and you cannot see any detailed metrics at all. No loop temps, etc. you can’t even change humidity set point from the app.

### 1/5 — Frustrating, annoying, yet easily fixable

*2026-02-05, version 3.5.5*

I have had this app for over a year and use almost every day to monitor our three WaterFurnaces, two Series 7 and one Series 5. Because the software does not remember my user selections from one session to another or from one device to another within a session or even my username or password, I have to repeatedly make selections that any decent app would simply persist in the data base. Apparently whoever wrote this app never actually used it. The same goes for whoever hired the app developer. LAME. Simple stuff like selecting the cost per kilowatt defaults to zero every time you open the app or simply select a different device!?! That’s just dumb. Every time you select a new graphical display of energy usage for a device, the app reports that there is a data error but, surprise surprise, there never is. Those graphs show data per device, again without persisting time frame or frequency, but do not consolidate data across multiple devices that you might have. This would be a trivially simple coding task…it’s a freaking data base app.

### 2/5 — Colors

*2026-01-29, version 3.5.5*

The colors in this app are hard to see it would be nice if they had a dark mode also would like to see more metrics for the units, including loop temperature intake temperature supply temperature

### 2/5 — Glitchy and in consistent performance

*2025-12-28, version 3.5.5*

I am using this app on a 7 series system with 3 zones. When opening the app, the screen displays one of the zones. When selecting the temperature control, the temperature reading will increase by 1 degree before changing the setting. Once the setting is changed, you must stay on the screen for about 30 seconds to ensure the new setting is stored. If you select a different zone before this time to view, then return back to original zone, it resets to previous temperature. Sometimes the setting does not stay set and will switch while viewing the display. 
Another nuisance, the app does not indicate what zones are open or calling for heat/cool. 
It doesn’t appear alot of effort has gone into this app. The previous system we had installed Neat thermostats. That app worked very well. WF could take some notes on how that works to improve this one.

### 1/5 — Unusable due to Bugs

*2025-09-12, version 3.5.3*

App crashes when attempting to set a schedule, struggles to connect reliably.

### 1/5 — Terrible app

*2025-07-31, version 3.5.3*

Never works and zero support. Find a different app.

### 1/5 — Garbage

*2025-07-31, version 3.5.3*

Written years ago and never updated. Looks old. Acts old. Performs old. Archaic functions.

### 4/5 — Works well

*2025-07-11, version 3.5.3*

This app works well, especially for control of the thermostat! Would be wonderful to see Apple Watch added to the functionality for simple control.

### 1/5 — When it says for age 4+…

*2025-02-18, version 3.5.3*

That’s the age of the programmers that wrote this system.
