AHU Supply Air Temperature

Hi all,

I have the Control sequence for this building I am working on and have noticed something that I really have no clue how to implement in my design. I have a portion of it in my model but the other portion is not modelled and I am not even sure if I can model it.

The AHU SAT is initially based off of OAT. Then if the average deviation of space temperature and the space setpoint is big enough, the SAT is then further modified. I have the values for the SAT based on OAT and have implemented that in the model using the OutdoorAirReset Setpoint manager which is working fine. Just I am wondering if there is a way the implement the second portion of the control.

If anyone has any tips they are greatly appreciated.

Thanks
