How to simulate the on/off time for an FCU using OS or E+?

Hi all: I am working on an FCU serving an open office. I want to simulate the FCU working status, compare with the actual working status to check if they match. In my model, I have an indoor setting temperature, supply air temperature, etc. seems I can simulate the FCU working time because it should depend on the indoor temperature. but in OS, the FCU has a schedule, "Always On Discrete", I am not sure how it impacts the simulation. I was wondering know if there is any way to simulate the on/off time for the FCU using Open Studio or E+? or can I decide the time using the simulated temperature? Thanks and any comments are welcome!
