Hi, i create a chiller system with 2-pipe circulation loop, to which i attached heating and cooling coils.Now what i want is that cooling and heating loads do not appear for same months. for example in july their is a cooling load so what i wanted is that heating load do not show up for that month. I know i need to define cooling and heating schedules separately, and then apply those schedules to "loop operation" of 2-pipe loop, but i dont know how to do this, as i did but nothing happened.  will anyone explain me how to do that?
