Upgrade Central Controller via Wi-Fi
If your Danfoss Link™ Central Controller is connected to Wi-Fi, it is set to do software updates automatically.
The latest software is version 4.2.1061
If your Danfoss Link™ Central Controller does not have Wi-Fi, you can update the software via USB / SD card, depending on the specific Central Controller.
Upgrade Central Controller with USB stick
First follow the link to identify, if your Central Controller with USB stick is enabled for Wi-Fi or not.
Download the software to a USB by clicking the relevant link.
Then go to your Central Controller and do the following:
1. Insert USB
2. Press the screen view Start mode
3. Select “House control”
4.Select “Settings”
5. Select “Wi-Fi and apps”
6. Select “App options”
7. Select “Software update”
8. Select “Update via USB”
9. Select “Update software now”
Update Central Controller with MiniSD Card
First download the latest software to a MiniSD Card by clicking the link.
Then go to your central controller and do the following:
1. Insert the MiniSD Card
2. Remove the front cover and press the SETUP pin for 3 seconds to enter the service area
3. Select “Software”
4. Select “Software Upgrade”
5. Select “Start Upgrade”
6. Select “Upgrade Software Now”
Note: Central Controllers from before 2010 are sometimes using software version 1.x.x. In that case, you need to update your Central Controller to version 2.1.35 before updating to the latest software.
With a customized user manual you can find instructions and advice for finding the settings that fit your exact needs.
Please select the heating devices you have bought and connected to your Danfoss Link™ and get a customized user manual by clicking “create user manual”.
Demount old thermostat
If you have an old thermostat on your radiator, you need to dismount your old thermostats, before you can install Connect Thermostat. In the video, we illustrate how to do it – depending on which thermostat you currently have.
Mount new thermostat and adapter
First, you need to identify which adapter is right for your radiator. Danfoss provides different adapters for different radiator valve types. Use the adapter selection guide by placing the different dimensions onto the valve to identify which adapter fits your valve.
The adapters supplied cover more than 90 per cent of all top mounted valves, both Danfoss and other brands. If none of the adapters fit onto your valve, it may be because your valve is old. In this case, we recommend that you buy a new valve.
Second, fit the correct adapter onto the valve. Insert batteries into your new Connect Thermostat and screw the thermostat onto the adapter and tighten. Leave mounting mode.
Please watch the how-to videos for a full explanation.
Now you are ready to create room and add devices on your Danfoss Link™ Central Controller. Please follow linkguide.danfoss.com to do this.
Adding devices
You can add devices to your Danfoss Link™ by following the Quick start guide on linkguide.danfoss.com. Remember to keep track of the devices you have added to Danfoss Link™, so you know in which room to mount the device.
Note: If your Central Controller says that the device was not successfully added, please reset the device (watch video below).
Moving or removing devices
If you wish to remove a device or move it to another room, reset the device you wish to move or remove (watch reset device video).
The device is now ready to be re-installed. Please follow the Quick start guide on linkguide.danfoss.com.
Power outage on Danfoss Link™ Central Controller
If there is a power outage, the Danfoss Link™ Central Controller will turn on, once it gets power again and will connect to your installed devices.
If the Central Controller does not get power again
Connect Thermostat or Room Sensor runs out of battery
When Connect Thermostat or Room Sensor is low on a battery, a battery icon will shown in the display and the Central Controller will give you an error message. If a Connect Thermostat or Room Sensors runs out of battery, they will go into frost protection mode.
Connect Thermostats and Room Sensors use 2 x AA non-rechargeable batteries each.
The freer passage the radio signal from the Central Controller has, the farther it can reach. House walls, metal objects, special constructions and other obstacles weaken the signal. Your Central Controller will give an alarm if it cannot reach a device for more than 1.5 hours.
If there are obstacles between your devices, you may need to install a Repeater Unit to extend the signal. Follow linkguide.danfoss.com to install the device. If necessary, you can extend the extended signal by adding another Repeater Unit as illustrated below. You only need one Central Controller for your home.
It can measure and control the temperature at a specific spot in your home.
If you place the Room Sensor close to your couch or away from a window, you ensure your desired temperature at this spot, because you optimize the actual temperature measurement in the room.
We recommend adding a Room Sensor in rooms with multiple radiators, because the Room Sensor balances the temperature across radiators based on the room temperature.
If your radiator thermostat is covered, e.g. by furniture, the Room Sensor will ensure your desired temperature in the room.
Add the Room Sensor to your Danfoss Link™ Central Controller in the same room as the Connect Thermostat you want the Room Sensor to be connected to.
Energy savings are achieved through a reduction in room temperature.
As a general rule, you can save 5% of energy consumption for every degree you lower the temperature at night. We recommend, you lower the temperature 3-4 °C at night and during working hours, e.g. from 21°C to 17°C. Also, activate vacation mode when you are on holiday.
When using Connect Thermostat, the average European saving potential is up to 30% on your heat consumption. Read more here.
The older your thermostats are when exchanging them, the greater your energy savings will be.
Connect Thermostat was the first electronic thermostat ever to achieve the prestigious AA energy certificate from eu.bac.
Please go to our Danfoss Link™ App Helpdesk and get the assistance you need.
To ensure that the radiator thermostat can reach the set temperature quickly, we recommend a difference between Away/Asleep mode and At Home mode at max. 4 ˚C.
Danfoss Link™ offers a precise and energy efficient heating regulation by adapting itself to the heating system. This takes approximately one week after installation. Therefore, during the first week you can experience fluctuations as the thermostats are learning when to start heating to reach the specific temperature at the specific time (adaptive learning). After this period, you can enjoy the perfect temperature in your home whenever you want it.
Below is an illustration of which Danfoss Link™ products are room devices and which are service devices.
The Danfoss Link™ Central Controller works in all residential units up to 300 m² with a maximum of 50 units per Central Controller (1 Central Controller + 49 units).
You can connect up to 50 devices in total to Danfoss Link™ Central Controller and thereof max. 30 Connect Thermostat to Danfoss Link™. Danfoss Link™ controls up to 10 devices in one room.
