ERROR(541): VENT for ductnode has a DEVC_ID or CTRL_ID, VENT ID:Inlet01

Hi all,
I am running an old model of 6 years ago with the new fds, and I got this error
"ERROR(541): VENT for ductnode has a DEVC_ID or CTRL_ID, VENT ID:Inlet01 ", which I didn't have in my old case study.
Is it now impossible to apply controls to the vent of a ductnode? How can I set the start of a jetfan without a control?
Thanks

This error was added because people were making VENTs and OBSTs disappear when they were connected to HVAC networks. You control the fan using parameters on the HVAC line.

How can I define the start of a fan? If I want that the fan initiate to work at 280 s, How can I set it without a logic?
Thank you in advance

Please read the User's Guide chapter for HVAC. It discusses this.
