I am modeling a building with basement or below grade parking garage. In the core or middle of the parking area are conditioned spaces cooled by FCUs. Ventilation air to the basement is provided by fresh air supply fans and exhausted by fans. Jet fans provide air circulation directed towards the exhaust. Conditioned spaces draw supply air from outside the room thru inlet air louvers and cooled by the FCUs. CO sensors are provided to check the level of CO in the parking area. To model this in OS 1.5.2, I used an airloop with outdoor air system, supply fan, setpoint manager (follow outdoor air temperature), uncontrolled air terminal to introduce unconditioned air to the conditioned space/zone. With this set up, I am getting warnings shown below:
* Warning * GetAirPathData: AirLoopHVAC="FRESH AIR SUPPLY" has no Controllers.
My question is if my set up is correct and if yes, how to address the warning because I can't locate the controllers mentioned, or if it can be ignored. Thanks in advance.
