Flair works with all mini splits, window units, and portable heaters/air conditioners that use an infrared remote control with a display showing the device's current state and settings (ex: fan speed, temperature, and/or mode).
I don't have a Remote Control
Ducted mini splits may not have a remote control, and instead, have a wall control that is directly wired to the mini split. You may be able to purchase a wall-mounted IR receiver and remote control for your model that is similar to the one below. Once installed, the Flair Puck can communicate with the IR receiver. Check with your mini split manufacturer.
If your remote looks like this one - has a display showing the current temperature and state (ex: fan speed, temperature, and/or mode) - you'll definitely be able to use Flair to control your device.
If your remote looks like either of these - there is no display, or the display only shows temperature and not state (ex: fan speed, temperature, and/or mode) - you may not be able to use Flair to control your device.
Types of Remotes
Remote controls with a display showing the device's current temperature and state (ex: fan speed, temperature, and/or mode) are called "idempotent remotes". These remotes send explicit commands, like "turn on power", "turn off power", "set temperature to 73°" or "set fan speed to high". The Flair App can accurately control devices that use idempotent remotes because sending commands creates predictable results.
Remote controls without a display - or displaying only temperature - are called "incremental remotes". These remotes send "incremental" commands, like "decrease temperature by one degree" or "change to the next fan speed". It's difficult to predict the effect of these commands and Flair may not be able to accurately control these devices.
