Subject: Re: [EnergyPlus_Support] AHU air temperature control
For the heating SP manager, it looks at the heating load and using the previous zone supply air mass flow rate, calculates a supply air temperature to meet that load. If there is no heating load, the SP is set very low. for the cooling SP manager, same thing happens, but if there is no cooling load, the SP is set very high. These SP's should be placed at different nodes so they do not get overwritten. And note that there is a mixed air SP manager that accounts for fan heat. Use this SP manager to place a SP at each coil outlet node so the resulting supply air temperature exactly meets the zone load (including fan heat).

Dear Richard,
Your suggestion is very helpful !
I used SetpointManager:Multizone:Heating object (due to multi-zones) at fan outlet air node of AHU, and the results shows that I really want it.
The discharged air temperature was varied from 16 deg to 35 deg. according to the zone load profile.
Anyway,
It was found that the capability of the SetpointManager:Multizone:Heating object also worked fine in summer design day.
I don’t know why E+ separate SetpointManager:Multizone:Heating and SetpointManager:Multizone:Cooling objects.
Could you please let me know the differences?
