Hi,
I'm trying to control both the setpoint temperature and the mass flow rate of a 5 zone HVAC system. You find the IDF here https://drive.google.com/file/d/1hjnxdoUBych6X7eQp_3Pkk6Z7VWxAoIs/view?usp=sharing.
I can change and the supply setpoint temperature and the overall supply mass flow rate, but I cannot change the individual zone mass flow rate.

Looking at the EDD file I see that for each zone I can use those actuators but none of them makes the change in the zone mass flow rate.

How can I solve this issue? SPACE1-1 ZONE COIL AIR IN NODE
