New A/C devices for better comfort

In each apartment, the 16-year-old air conditioning system was replaced with new INVENTOR brand units. These air-to-air heat pumps can be used for cooling, heating and dehumidification. Their efficiency is twice as high as the previous units! In addition, the units can be adjusted on site via remote control and even worldwide via WiFi using my app. During the day, they profit from solar power produced with my own PV-panels.
