If it is visible then Danfoss Link CC has Wi-Fi support.

 If your Danfoss Link CC Panel has no Wi-Fi option, and you would like to replace it with the new one(with Wi-Fi option available),  please contact your Installer.

If your Danfoss Link CC has Wi-Fi you can control your Danfoss Link system from an App on your phone or tablet if you have at least Android 4.1 or iOS 8.0 installed.

Future software updates will automatically be downloaded to your Danfoss Link CC enabling new features and improvements.

Check your Danfoss Link CC connection

There are many factors that might cause your Danfoss Link CC to be off-line occasionally. Before spending the time troubleshooting your home network, you should verify that one of these more common issues aren’t causing the problem:

  1. The connection to the Internet at your home is down
  2. A power failure at home
  3. There is a problem with your Wi-Fi router

You can test this by verifying that your phone can connect to the Internet via the same Wi-Fi network.

If you are still experiencing problems – check these troubleshooting steps:

  1. Restart Wi-fi Router and/or Access point
  2. Check Wi-Fi signal strength at Danfoss Link CC – Try moving the Danfoss link CC closer to the router, if successful this may show that the signal strength is not strong enough to reach where you would like to locate your unit.

  4. Try to connect the Danfoss Link CC to a mobile hotspot using your smartphone

Is it possible to manage more than one location with the same App?

How many thermostats can I control from the same App/Smartphone?

You can control one thermostat at the time, and pair up to 100 devices*, so you can switch between thermostats that are within Bluetooth range.

*Each paired thermostat requires 5 kb free space on the smartphone  

What to expect in terms of range between the App and the thermostat?

The range depends on the surroundings and building construction, but as a rule of thumb, the range should be up to 10m.

Will my smartphone support the Bluetooth technology?

Bluetooth is supported on smartphones from iPhone 4S and Android devices with software versions from 4.4. For tablets please refer to manufacturers information.

What is Bluetooth?

Bluetooth is a short-range radio frequency that operates on 2,4 GHz and is capable of transferring data between two devices. Bluetooth smart is especially known for very low energy consumption. The maximum range is approx. 10 meters depending on the surroundings and building construction.
