Electric underfloor heating - thermostats

Error type E4 means that the room temperature sensor value is too high or too low. This is an unrecov­erable error. Contact service to find a solution. The thermostat requires a restart to operate again.

Error type E3 means Thermostat is over­heated, heating is turned off. Wait until ther­mostat cools down. The thermostat requires no restart, but will start heat­ing when the temperature is lowered.

Error type E2 means Floor Sensor short-circuited. Contact service to find a solution. The thermostat requires a restart to operate again.

Error type E1 means Floor Sensor discon­nected, meaning the connection to sensor is lost. Contact service to find a solution. The thermostat requires a restart to operate again.

Yes. There will be an icon in the room list of the app showing if window open are detected.

The installed floor sensor is identified by measuring the ohmic value.

During the Technician setup the correct installed floor sensor can be selected.

The installation can partly be done without Wi-Fi, since the installation of the Danfoss ECtemp Smart thermostat is split in two.

Technician setup - this can be made without Wi-Fi, so that the thermostat can start temperature regulation.
Wi-Fi setup – this cannot be done without Wi-Fi connection. Meaning you will not be able to see the thermostat in the app before Wi-Fi has been setup.

The power consumption in kWh for the actual thermostat can be found under [Thermostat information].

Lost Wi-Fi connection will give an alarm in the app, and you can chose to get a Push notification as alarm on your phone.

Push notifications can be enabled by choosing [Settings] and [Notifications]

The Smart thermostat can regulate the room temperature without Wi-Fi connection, if Technician setup has been made, and it is displaying the actual room temperature.

Time zone is set by the phone during installation, and it will stay like this, even if you move the phone to a different time zone later.

Time will be maintained and adjusted according to summer and winter time automatically.

Actual time on the thermostats will be displayed on the main screen – showing Living zone.

How to read out HEXA code form Danfoss ECtemp Touch:

Access [Menu] and then [Settings]

Choose [Info]

Choose [Read Out] or [Read Out Codes]

Result: 16-digit code e.g.

Insert code into the Smart App. Use only characters e.g.: [12010E9928224181] and confirm.

Manual temperature can be used when the heating schedule is not needed in an individual room or the Living Zone.

Manual temperature is particular useful if you have a guest room that is rarely used. The heating schedule could be active when the guest is staying in the room and when the guest leaves you could switch to a lower manual temperature saving you energy.

Please note that any room can be changed into an Individual room by following the instructions in this article: What is Living Zone?

Manual temperature for an individual room can be activated as described here:

Access the right side panel of the Danfoss ECtemp Smart App.

Access the right side panel of the Danfoss ECtemp Smart App.

Scroll down to the "Individual rooms" section.
Click on the room name of interest.

Slide "Manual temperature" from "Off" to "On"

"Manual temperature" is now activated.
Choose a different manual temperature if needed.

We recommend that you adapt the heating schedule of the Living Zone and the individual room(s) to your needs so Danfoss ECtemp Smart knows when are you at home and when are you away or asleep.

Additionally you could consider what the needed temperature for each room should be when you are at home and away or asleep. Generally the rooms where you spend the most time would most likely require a higher temperature than the rooms where you are less often or where you sleep. 

Approximately 5% of energy savings is possible for every degree of Celsius the temperature is lowered in the home.

The following steps show how you can remove the connection to a Danfoss ECtemp Smart thermostat from the Danfoss ECtemp Smart App.

(*) Key settings

• Refer to your Wi-Fi router documentation to learn how to update your settings.
• WPA2 Personal is currently the strongest form of security offered by Wi-Fi products, and is recommended for all uses.
• Danfoss ECtemp Smart is using a Wi-Fi at 2.4 GHz, and other home products might be using the same 2.4 GHz frequency-band, and might disrupt your Wi-Fi network. Try turning off any products that might interfere with the Wi-Fi wireless connection, like:
  - Cordless phones
  - Burgler alarm system w. room IR sensors
  - Baby alarms (Monitors)
  - Microwave ovens
  - Bluetooth devices
  - Wireless audio/video equipment

Check your smartphone or Device connection

In case of a lost connection to the Danfoss ECtemp Smart App check that your device/ Smartphone are connected - a ‘lost connection’ notice will show on the screen. Follow the device message to reconnect to the network.

Check your Danfoss ECtemp Smart thermostat connection
There are many factors that might cause your Danfoss ECtemp Smart thermostat 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:

• The connection to the Internet at your home is down
• A power failure at home
• 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:

• Restart Wi-Fi Router and/or Access point
• Check the router parameters – the table above shows the recommended settings for the Danfoss ECtemp Smart.
• Try to connect the Danfoss ECtemp Smart to a mobile hotspot using your smartphone
• Restart the Danfoss ECtemp Smart
• Check for 2.4 GHz interference – there is more details below about the types of devices that could be interrupting the signal.
• Check the parental controls on your Wi-Fi router/access point and other firewall settings (Refer to your Wi-Fi router documentation to see if this feature is enabled on your network and how you can exempt the Danfoss ECtemp Smart from these restrictions).
• Update your Wi-Fi access point or router’s firmware.

When the app is showing ”No connection” to thermostats, then connection between app and thermostats cannot be established.

Thermostats without internet connection will still be working, and they will be regulating the room temperature according to the settings programmed in the app during the last connection.

All settings are stored locally in the thermostats, so they can be setup and used without internet connection.

To find out why there is no connection – please go to the “No connection” section of our support site and follow the trouble shooter.

Currently the Danfoss ECtemp Smart app is only developed for Android and Apple IOS.

Currently the Danfoss ECtemp Smart app is only developed for Android and Apple IOS.

Danfoss ECtemp Smart is available on iOS 7, iOS 8 and iOS 9. The android version is available on android 4.4.x, 5.x and 6.x.

A Living Zone is a single room or a number of rooms that can be set to follow the same timer settings when programming comfort temperature and economy temperature for your house. Specifically it is a list of rooms sharing the same heating schedule for when you are at home and away or asleep.

Living Zone is a quick way to control the heating where you live and can be set directly from the ECtemp Smart App.

Comfort temperature and economy temperature is still adjusted individually.

Rooms can be added or removed from the Living Zone.

An example of a room that you might prefer to handle outside a Living Zone can be your bedroom, as it is typically used at other periods than other rooms in the house.

You can move rooms (thermostats) in and out of the Living Zone heating schedule as described here:

• In the Danfoss ECtemp Smart App, activate menu by tapping the menu icon (tree lines) in upper left corner of the main screen.
• Tap [Schedule] and you will get a list of the installed thermostats
• Tap the pencil icon in upper right corner and you can now slide the rooms (thermostats) between “Living Zone” and “Individual room”
• Save the new setting by tapping the checkmark in upper right corner

The Danfoss ECtemp Smart system allows you to share a “House” (Connection and setup of one or more thermostats at same location) with other persons, but before doing this, it is important to notice – that when sharing a “House” you also transfer full rights to manage or change your system.

• New user can install or delete thermostats.
• New user can share with new persons or delete current users.

You share access to your installed Smart thermostats by pressing the three lines in the upper left corner of the main screen in the Danfoss ECtemp Smart app:

• Here you choose [Settings]
• Then press [Share house] to open a page that will show you a code.
• The code will for security reason only be valid for 2 minutes.
• The person receiving the code should press [Receive house] and type in the code from sender. If this is not done within 2 minute timeframe, then sender has to create a new code and share.

Some Samsung phones have a “Smart Network switch”. This Smart Network needs to be switched off for the phone to connect to the DEVIsmart network. Go to [Settings] and [Wi-Fi] on your phone and disconnect the “Smart Network switch” and try to connect your ECtemp Smart App to your Danfoss ECtemp Smart.

The Danfoss ECtemp Smart thermostat supports Wi-Fi routers with 2.4 GHz frequency. Most Wi-Fi routers that support 5 GHz also support 2.4 GHz by default to ensure the widest compatibility with Wi-Fi products. Please consult the manual of your router to learn more about what frequencies it can support.

In case of connection issues please make sure that your phone or tablet is connected to internet using Wi-Fi or mobile data connection and that the Danfoss ECtemp Smart thermostat has access to Wi-Fi with working internet.

To troubleshoot this, please follow the article “I have no connection”.

Please try to search for the Wi-Fi network one more time.

If that doesn't work you may have a hidden network and in that case please consult the manual of your Wi-Fi router to find out if your Wi-Fi network is hidden (SSID Broadcast disabled) and how to make your Wi-Fi network visible (SSID Broadcast enabled).

Once you have completed this step you can connect the Danfoss ECtemp Smart to your Wi-Fi as described in this article: How do I add the Danfoss ECtemp Smart App to my Danfoss ECtemp Smart thermostat?

When the Danfoss ECtemp Smart thermostat is connected to your Wi-Fi you can afterwards hide your Wi-Fi network again if needed by consulting the manual of your Wi-Fi router.

If you are unsure on how to configure your Wi-Fi router we recommend you contact the provider of your router.

In very rare cases the Wi-Fi network may not be shown due to the chosen frequency on the Wi-Fi router.

The Danfoss ECtemp Smart thermostat supports Wi-Fi routers with 2.4 GHz frequency. Most Wi-Fi routers that support 5 GHz also support 2.4 GHz by default to ensure the widest compatibility with Wi-Fi products. Please consult the manual of your router to learn more about what frequencies it can support.

The Wi-Fi password can usually be found on a label on your router or on the information sheet that was provided with your router. This is a standard practice for most internet service providers. If the Wi-Fi password is not found then try to contact your internet service provider to see if they can provide you with the Wi-Fi password.

Your internet service provider may suggest that you manually reset the router to its factory defaults and follow the instructions in the routers manual on how to setup the Wi-Fi again. Please be aware that you should under no circumstance reset your router to factory defaults unless the provider of your router says it is okay.

If you no longer have the manual of your router you can probably find it on the internet. Start by locating the model name and number on the router itself and search the internet for the phrase "<insert model name number> manual". Please be aware that if you reset your router that all your connected devices may need to be reconnected to your Wi-Fi network again.

Please contact your internet service provider or the information you received with your internet.

If the thermostat is configured and shows a temperature, but not configured for Wi-Fi it will start pulsating blue when the control button is touched. When the thermostat is pulsating blue, please choose [setup thermostat] in the app.

You can only access the thermostat if you have created a secure parring with it.
