The Zone Heating Supply Air Temperature is for the purpose of sizing the zone heating air flow. The "Rated Outlet Air Temperature" is used to infer the physical size of the heating coil. Neither of those are for control purpose.
To control water coil outlet air temperature in AirLoopHVAC, you need to used Controller:WaterCoil object associated with Setpoint Manager object to set the water coil outlet node temperature setpoint. You can refer to 5ZoneVAV-ChilledWaterStorage-Mixed.IDF in the EnergyPlus ExampleFiles folder for how to do that.
