I can't seem to get this right... What is the correct way to modify the volume flow rate of a supplyfan (Fan:ConstantVolume) in an airloop based on a time schedule to simulate a four mode operating switch (off/night/day/boost ) in a multizone model? There are no heating/cooling coils in the system, only a HeatExchanger before the OutdoorAir:Mixer. The system should operate with 100% fresh air. At the moment I have AirTerminal:SingleDuct:Uncontrolled in every zone (sum of the max terminal flow rates = max flow rate of fan:constantvolume).
summarizing: How do I make an airloop operate at 50% of max flow rate between time x:xx - y:yy, 75% between time x:xx2-y:yy2 etc.
Is there an example file for a similar case?
