Hi,

I am trying to modify the "Server exit air temperature" as calculated by EnergyPlus. Basically EnergyPlus uses a steady-state equation to compute this temperature and I am trying to incorporate a transient scheme using EMS. The variable that I am trying to map for this purpose is "ITE Outlet Dry-Bulb Temperature". I have declared this as an EMS Sensor object and created the variable Taex for this purpose. However, no matter what I do, I cannot access this variable and modify its value using my code. I tried to use an EMS actuator but cannot find a suitable one that will control temperature. How can I accomplish this. Any help would be greatly appreciated.

Thank you for that answer, I appreciate it. Can you give me any guidelines on how to access the source code and make changes (to add an actuator). I would like to work with the source code from v8.4, which is available in C++. Thanks.
