How it works

A quick look around the Danfoss Icon2™ system

Danfoss Icon2™ delivers precise and efficient control of underfloor heating with smart-home compatibility and the flexibility of a solution that works with 90% of applications.

Automatic balancing

Maintaining the right balance in every room

With Danfoss Icon2™ automatic balancing, the system will reduce the ”on” time for the shorter pipes found in small rooms and prioritize the longer pipes found in large rooms, in times where heat demand is high. This ensures all rooms will share the limited energy available in the way that delivers the greatest possible comfort and efficiency.

The benefits of automatic balancing

Energy savings
A balanced system can work with a lower supply temperature

Simple design
No calculations are needed as Danfoss Icon2™ takes care of it all

Easy installation
No need for pre-setting

A more accurate room temperature in all areas of the house

Smart home compatibility

Danfoss Icon2™ integrates seamlessly with Danfoss Ally™ solutions and can be controlled from anywhere by the Danfoss Ally™ App, so end-users can enjoy all the benefits of a true smart-heating system. Set the temperature to 21°C degrees and that’s exactly what it will deliver.

The Danfoss Ally™ Gateway is the only extra device needed to get cloud connected and gain all the smart heating features on top.

Because Danfoss Icon2™ is built on Zigbee 3.0 protocol, customers can also control their heating with other 3rd party Zigbee based smart home solutions.
