The fireplace scenario

Daikin systems are flexible and easy to adapt for any room, including spaces that contain additional heat sources, such as a fireplace.

› Rooms that contain a fireplace tend to be warmer and have a temperature that is higher than the original setting.
› When there is a temperature difference in a room and a fireplace is in use, the air conditioner will switch to a “fan only mode,” to distribute heat from the fireplace to other rooms.
› The air flow decreases, the more the room temperature gets to its original setting. Once the room temperature drops below set point, the compressor of the unit will start again.
› If needed this function can be disabled by the user if no fireplace is present. 

Inaudible to hear 

The perfera indoor unit is practically inaudible. The unit runs so quitely, you will almost forget it's there.

Fresh, healthy air and comfortable air flow

Creating a healthy indoor environment is essential for regions with colder climates. Daikin uses Daikin Flash Steamer technology and a Saranet filter to improve the air quality of your office, home or store. Daikin intelligent eye also directs air flow and switches the system to an energy efficient mode when no occupants are detected in a room. The fan (speed and noise level) guarantee a unit’s seamless operation.


The Optimised Heating 4 range includes additional features to reduce ice buildup, including an enhanced bottom plate. The system can also defrost ice faster to achieve more comfort and reliablity.
