My EnergyPlus model contains IT Equipment with Supply Air Node name =ZoneIN.

When outputting ITE Air Inlet DryBulb Temperature (HVAC System Type Step) and corresponding System Node Temperature ZoneIN (HVAC System Type Step) , these values however deviate in a way which is difficult to interpret, although the two output time series logicall should be identical.

Can anyone explain why these two output variables differ, and why ITE Air Inlet DryBulb Temperature (HVAC System Type Step) has only a fraction of valid values as a time series with System Time Step. ? What is the underlying algorithm by which the output values are derived (mere averageing for skipped time steps is apparently not the case).
