First the user will go to the DB Builder app.
Then, once inside the app, the user will navigate to the equips (vav's) they will like to bundle up and make sure they have a ref to the associated equip (ahu) they serve. You can find the all this on our demo project.
Then the user will have to either add new points on the associated equip (ahu) they serve to get the results. The points can be whatever the user is looking for. We recommend adding unique tags like “rollUp” and another tag based on that point.
Historize It would be best to create new points if the user wishes to have histories for those logical points. |
Once that is done, the user will navigate to one of the bundled equips via the Nav Tree (VAV-01 in our case).
Then select the Logic Builder app → New from the App Launcher Menu.
In the below pop up, the user would give the program a name and what it runs on. Then select the points to use, in our case it would be AirFlow, AirFlow Setpoint, Damper, Occ Mode, Room Setpoint, and Room Temp.
Then once the program is created and open, the user needs to add a two variables for the deltaTemp and deltaAirflow that we want to include. To add them, the user would select "+ Add Variables" in the right menu and select Var option.
Then for the new variable, give it a name and make sure its a program variable. The data type for this is going to be Number. Should look like below.
Then hit Okay, to enter a value for the point. Leave it as 0 since it will be written to based on some logic.
That should be it, do that for both variables.
Then create the below logic with the new variables. We want to include deltaTemp and deltaAirflow in our bundle so thats why we created them to use later on.
That would be it for this program. The user would then save it.
