I have 8 VAV dampers (2 per floor) that are controlled using a 0–100% command, corresponding to vMin–vMax.
Currently, some of the VAV dampers have the same vMin and vMax values, but this may change later.
When there is a cooling command, the corresponding VAV damper should switch to vMax = 100% in summer mode.
When this change to vMax occurs, I also need to increase the setpoint of the ventilation system accordingly.
Example – Setpoint Airflow Calculation:
Cooling Command Status Value
Cooling Cmd 1 Not active 250
Cooling Cmd 2 Active 650
Cooling Cmd 3 Active 850
Cooling Cmd 4 Not active 180
Resulting ventilation system setpoint = 1930
The 70% that i first decribe i see was wrong. I have change that part now i the main topic.
