Multiple indoor units can be grouped together for centralized control through the FGLair, Intensis AC Cloud or Airstage Mobile App accounts.
The apps are free to use and a single account can operate up to 24 indoor units. User ID and password can be used to log in from multiple mobile devices with Airstage Mobile app allowing up to 5 accounts per indoor unit.
