The Aura Remote service, offered by Thermia AB and its partner Sikom Connect AS, enables remote control of the Thermia Aura ZR and Thermia Aura ZP air-to-air heat pumps.

Aura Remote mainly consists of a central unit and a radio node that ensures remote communication with your heat pump via the Aura Remote app. The central unit you use today uses the mobile network 2G.

Right now, a phase out of the GSM network (2G & 3G) is taking place all over Europe in favor of being replaced with new technology (4G & 5G). The phase out of the GSM network is entirely driven by the respective mobile network operator

• In Sweden: the 2G network, which is operated by two main players (Telia and Telenor), will operate normally until the end of 2025. The phase out of the 2G networks is planned to be carried out by the operators between 2025-2027. For more information on current dates, please visit the website of the respective mobile network operator or visit the various mobile network operators' common information channel bytnät.nu

• In Finland: the 2G network will operate normally until 2029. After the end of 2029, it will no longer be possible to guarantee operational stability or coverage of the 2G network.
• In Norway: the 2G network will work normally until the end of 2025. The phase out is planned to start in 2026 and completed during 2027

The Aura Remote Central Unit is not bound to a specific mobile network operator, which means that as long as there is a functioning 2G network (regardless of operator) within range of the central unit, the Aura Remote service will work. 

However, keep in mind, from the start of the phase out of the 2G network, the risk gradually increases that there is no longer a 2G network within range of the central unit, which means that the Aura Remote service will no longer work.

The solution
Thermia's partner Sikom Connect AS offers a future-proof version of the central unit that uses the 4G mobile network. If you are interested in continuing to have the ability to control your Thermia Aura heat pump remotely, we recommend that you replace the current central unit with the new variant that supports 4G.  We recommend upgrading to the new central unit now, but no later than 2025 to avoid being affected by any disruptions.

The radio node (mounted in the heat pump) and the accessory “humidity sensor” will continue to work with the new central unit.
Instructions on how you easily upgrade your system will be sent together with the new central unit.

Do 4G mobile network have as good coverage as 2G?
As mobile operators shut down 2G and 3G, they are expanding and increasing the capacity of both 4G and 5G networks, which in the long run means that mobile coverage will be better than before. If any uncertainty regarding 4G coverage in your area, we recommend reading more on bytnät.nu (Sweden) and the various local mobile network operators' coverage maps for 4G.

To secure the ability of remote controlling your Thermia heatpump (Thermia Aura ZR or ZP), you as an existing customer are offered to update the Aura central unit to a version with support for 4G.
