Features
UVC sterilisation
The UVC module helps keep the indoor air clean and healthy.
56°C Steri-Clean
The indoor heat exchanger is heated to 56°C for 30 minutes to kill bacteria and viruses, then cooled down at once.
Eco sensor
The sensor detects people up to 8 m away across 120°, sends the air towards them or away from them, and switches to energy saving within 20 minutes when the room is empty.
Silence
The fan, air ducts and motor are designed for a low noise level.
I Feel
The remote control measures the temperature where you are in the room, and the unit works to that reading.
10°C Vacation mode
It switches on when the temperature drops below 10°C, to protect pipes in winter in empty holiday homes, garages and basements.
Heating cable (Nordic)
The Nordic version of the outdoor unit has a heating cable for cold winters.
hOn Wi-Fi
With the hOn app you control the air conditioner from your phone or tablet, also with voice assistants.
