How to control the supply inlet temperature in IdealLoadAirSystem-object?
I'm using the IdealLoadAirSystem-object in energyplus, and can see from the results, that when my internal gains increases (and I then get a cooling demand), the heating of my supply inlet temperature stops and then the room receives unheated outdoor-air e.g. at 4C.
This makes sense since IdealLoadAirObject tries to stick to the thermostat setpoint temperature (21C), but instead of decreasing the inlet temperature, I want to increase the supply air rate. How to do this? 1) Can IdealLoadAirSystem do this via specific settings, or 2) do I have to add another/new HVAC-opbejct?
The calculation is 100% thermal.

Maybe I'm not reading this correctly, you want to keep the same supply temperature from heating and increase the supply air flow when there is a call for cooling?
Yes, I want to keep the inlet temperature at e.g. 21C, but the amount of air coming into the room to go from e.g. 2/hr to 4/hr when a cooling load occurs. Does that make sense? :)
