The Danfoss Icon2™ Main Controller is easily installed onto the wall, either by using the included screws or a DIN rail and the built-in spirit level guides to the perfect positioning.
There are no loose components – just unbox and installation can begin!

The innovative cabling saves you time, and the plug'n' push terminals make installation easy with minimal use of tools.
From here, the most important tool needed is a smartphone.

The Danfoss Icon2™ Commissioning App guides step-by-step and has everything needed to get the job done.
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 Danfoss Ally™ Gateway is the only extra device needed to get cloud connected and gain all the smart heating features on top.
