BACnet & MTT

1. Smart IoT Communication Output Options

The Smart IoT unit offers BACnet IP (Internet Protocol) and cloud-based environmental monitoring. Either or both options can be used.

AtmosAir provides a BACnet IP configuration tool allowing the installer to program the Smart IoT unit at the installed location. Users can revise the BACnet IP configuration using the same tool eliminating the need for AtmosAir factory assistance.

Cloud-based environmental monitoring is always active and available on the Smart IoT unit; however, a cellular modem option must be purchased from AtmosAir to provide data communication to the cloud. Your salesperson will be glad to assist you with this option.

2. BACnet IP Communication Option

Introduction:

The Smart IoT unit has a BACnet IP option to allow the user to send data to their building automation controls and network.
