It is first necessary to check your unit's compatibility with the Airzone system. To do so, click on the following link Airzone Control.

If your AC unit is included in the list of compatible units, it can be controlled by the Airzone system. The right gateway must be used for this. Each gateway has its own technical data sheet which explains the connection and how it operates.

Check that the gateway's LED light up as indicated in the technical data sheet.

If everything seems to be correct, but the AC unit does not operate, see: The dampers open and close, but the AC unit does not start up.
