MLM INTEGRATION WITH BMS
Notice how the airflow volume decreased with a change in control disk position.
The total airflow volume for the zone is displayed on the master controller for that zone, in this instance the
Wallstat. For this zone (17) only the master controller was fitted with an airflow sensor, hence the distribute
function was selected. The zone consists of three equal size diffusers.
For a BACnet BMS system this total flow value is found in BACnet point variables AI: 60...119.
