[EnergyPlus_Support] Question about enthalpy opening control.

I wonder one thing more about Airflow Network enthalpy control.

In the AirflowNetwork:Multizone:zone

When I control the openings by enthalpy control, I can't understand delta H = 0

Where can I set the setpoint enthalpy?

There's setpoint regarding "temperature" only. 

Is this also refers to  "Ventilation Control Zone Temperature Setpoint Schedule" ? 

But I think this is only defining temperature, there's no humidity included.

When control the openings by delta T. it's clear. 

At first this refers to "Ventilation Control Zone Temperature Setpoint Schedule"

If the outdoor air is lower than set point (I set 26'C), ventilation is available. 

and then multiplier on venting open factor is multiflied based on the delta T(indoor air temp - Outdoor air temp)


When it comes to enthalpy. 

all the process is the same, except setpoint H.

I don't know where can I set this. 

Please give me your help.
