CONCERTO Connect by Flextherm

★★★★★ Just installed this system two days ago - Thursday, January 14, 2021. While the heated floor will heat and cool, the thermostat only works manually. The cell app is installed and shows what I have programmed into the system to manage the stat for each day of the week, nothing happens via the cell app. I have to assume there is a problem with the software, and it's connectivity to communicate with the stat. So I would like to hear back from the support team to resolve the problem. However, I have endured to see whether I could resolve this issue. As it turns out, the "troubleshooting" section of this "comments section" on the website, offered a possible solution and when the two units don't communicate, the issue could be how the startup was done. Since there is no "start up" procedure that is defined in the paperwork, it needs to be re-written into an SOP for the future buyers of this product. Doing so in a step-by-step process is necessary to preserve the future of what I now think is a very good product. When I turned my cell phone on to "AUTO" everything worked; it had been on "manual". Not knowing that this needed to be done is the fault of the designers and lack of instructions to do so - albeit they assume that everyone "knows" how to do what comes second nature to them. Additionally, when the installation directions are re-written by them, put ALL the installation direction on one sheet. The floor probe installation is poorly described on the booklet entitled "Flex Snap Installation" guide, while the "Green Cable Surfaces" newspaper type sheet has better information on how and where to install the probes. They need to both be updated to say the same thing, so the installer doesn't have to waste time trying to find out where to place them. Having navigated this gauntlet, I am upping my satisfaction on the product. I caution, however, for the staff to please upgrade the instructions - particularly the thermostat information, since it is the primary controller of the very product you're trying to be the best in.

★★☆☆☆ After adding three thermostats for electric in-floor heating, it will no longer allow us to update any of the settings. Anything we try to update just gives an error to try again later.

★★☆☆☆ Stopped working. LCD on thermostat died after less than a year and the app was my only way of adjusting the temperature...

★★☆☆☆ Android version is not working well. Can't connect

★★☆☆☆ Can't even get the app to load at this point. What a joke of a product.
