Danfoss ECO FAQ's
Why are my radiators heating doing night set-back periods?

The reason might be, that Adaptive learning is enabled.

The adaptive learning function (Forecast) ensures that the comfort temperature is reached at set time. The warm up time is continuously adjusted according to seasonal temperature changes.

  1. Adaptive learning ensures the wanted temperature at the wanted time (here 20 °C at 07:00).
  2. Adaptive learning uses data from the previous 7 days to be able to reach the correct temperature at the right time.
  3. Adaptive learning is sensitive to large, rapid temperature changes.

 

 Winter: Long warm up time                                        Spring/fall: Short warm up time

 

In case you would like to disable this feature, it can be done in following way:

Swipe to the left from the App home screen ->

Go to settings ->

Advanced settings ->

Adaptive learning OFF

 

If you turn Adaptive learning OFF, heating will be running according to set schedule.

Is my smartphone compatible with Bluetooth? / Slow or no connection.
Danfoss Eco™ is using Bluetooth to communicate with Danfoss Eco App™.
To download and use the Danfoss Eco™ App you must use a smart phone device that follows these requirements:
  • IOS: Version 11 or higher and more recent models are compatible. The Danfoss Eco™ App is optimized for iPhone usage, but can be downloaded as well on iPads. Remember to search for iPhone App as we do not have a dedicated iPad App.
  • Android: Version 7.0 or higher*
    *Android operative system is used by many smartphone manufacturers around the globe. These devices are communicating via Bluetooth in different ways and with different level of success.
Danfoss is aiming to ensure compatibility within widest possible range of popular Android smart phones.
Internal tests have shown that some Android smart phones are not responding well to Bluetooth devices, hence the connection is not always stable.

How can it be?
The challenge with Bluetooth connection is often related to battery powered devices that is optimized for long battery lifetime – no matter the type and brand. Bluetooth devices optimized for long battery lifetime does not communicate with the same intensity as mains powered Bluetooth devices. It means you might experience full compatibility with a Bluetooth loudspeaker, but encounter problems with the same smart phone device, trying to connect to a battery powered device. (Please notice that Bluetooth headsets etc. is not optimized for long battery lifetime).

If you are experiencing slow, or no connection to Danfoss Eco™? You might use this workaround.
You have Android device and you have some challenges in establishing a Bluetooth connection it is recommended to try the following:
  1. Activate the Bluetooth protocol by turning the wheel or pressing the button whilst the Danfoss Eco™ App is searching for connection. Turning the wheel or pressing the button is increasing the ‘amount’ of Bluetooth communication and also the chance that connection can be established.
  2. If you have an iPad or iPhone, then try to establish connection from one of these devices. If you succeed, then it is due to the Bluetooth connection speed on your Android device.

Why set temperature isn't changing at the scheduled time. "Time zone" or "Summertime" is incorrect.

If radiator thermostat doesn't change set point temperature at the scheduled time, then you need to re-connect your smartphone with the internet access to the thermostat and new time will be updated via the internet automatically. If the issue remains the same, remove batteries from the thermostat or reset to the factory settings.

View page
Is it possible to manage more than one location with the same App?
It is possible to control as many locations as you like although it is not possible to group thermostats, so you need to know which ones you have in your primary home and which ones you have in your second home. View page
Can I use the thermostat without an App/Smartphone ?
Yes, if the thermostat haven’t been connected with an App, then it will operate as a standard thermostat. The set point in the display will be the temperature target. It is not possible to do schedule programming directly on the thermostat. View page
What is Bluetooth?

‘Enable location’ service. Why is my Android phone asking me to do this?
From Android 6.0 and later versions, Google has changed the permission requirements for Bluetooth LE scanning. This means "locations services" on the Android smart phone device must be enabled to search for, and establish connection to Danfoss Eco™. This requirement is implemented by Google not only for Danfoss Eco™, also for other Bluetooth devices. View page

Error E9. What does it mean and what should I do?

Error E9: restricted valve closing ability. Danfoss Eco™ is installed on the valve incorrectly.
Pease check the installation following the next steps:


1. Be advised that Danfoss Eco™ should have enough free space in place of installation for precise room temperature measurement. It means Danfoss Eco™ shouldn’t be covered by curtains, decorative radiator coverage, furniture, etc. Also, distance between installed thermostat and another heat source (radiator, pipe, riser, etc.) should be enough long to prevent negative influence on the temperature regulation performance.  

   
2. Check if valve’s spindle moves (up/down) without any resistance and does not have any leakage;


3. Check if adapter was matched according to the valve type (installation video: https://www.youtube.com/watch?v=zC8ThdqPH1s&t=8s);


4. Make sure that adapter and Danfoss Eco™ is tighten enough. Screw Danfoss Eco™ onto the mounted adapter until a click sound appears;


5. Pull one battery out and put it in Danfoss Eco™ again. This action will launch valve exercise procedure (from fully opened to fully closed position);


6. If after applying four steps above the issue remains the same, we highly recommend you to get technical support by the link: https://linkapp.danfoss.com/en/request or contact our Customer Service Center: 24/7 - International number, Tel.: +331 83 82 37 90.
