How to put schedule for switching on SPLIT HVAC in Openstudio?

In my model there are 2 thermal zone swith an unitary SPLIT HVAC System each that are operated independently. In reality, these Split AC are operated manually when the building is occupied, e.g. for example in a residential building when people come home after work they switch on AC.

Now I am not sure which class to address while creating the schedule? For example, I could put the schedule for the cooling set point very high when the building is not occupied. But I was wondering if there is a cleaner solution, e.g. operational schedule of HVAC system or I saw something like Availability Manager.

If you are modeling this with a ZoneHVAC system like a PTAC, then you could use the availability schedule.

If you are modeling with an AirLoopHVAC based system, then you could use the "HVAC Operation Schedule" on the "Control" tab of the air loop interface.

@Kyle Benne Thanks al lot. I got it. Is there also an options for an operational/availability schedule when I am simulating with IDEAL AIR LOADS?
