Is SetpointManager:MixedAir only for Coil:Cooling:Water? SetpointManager:MixedAir is often used to calculate a supply air temperature setpoint by accounting for supply fan air temperature rise in an airloop. It works with Coil:Cooling:Water, but when I change the cooling coil to Coil:Cooling:DX:SingleSpeed with CoilSystem:Cooling:DX, SetpointManager:MixedAir does not work. The supply air temperature at the drawthrough supply fan outlet becomes much higher than I expect.
