With the AirTouch 4 App you can turn on the climate control, change the mode and fan speed, or adjust the temperature when you are out of the house so you can arrive home to the climate the way you want it.
When no one is home, the app can send you a temperature alert if home is getting too hot or cold, inviting you to turn on the air conditioning remotely.
You can even turn off your system away from home to make sure you don’t waste energy cooling or heating an empty building.
