I'm trying to understand how the HVACTemplate:system:unitary, defined with a dx:singlespeed cooling coil, works to meet the setpoints I specify. From my reported output, it looks like the zone in question is meeting its setpoint almost exactly every hour (to 0.001 degrees).
I know in reality this is not how a central air system works; with more of a "margin" before it kicks on and off. Essentially:
A) How do I tell when the dx:singlespeed coil is kicking on and off, so I can tell if it is cycling too fast?
B) If possible, can I modify the margin of the HVAC cooling system so that if I set the room setpoint to 70, with a "margin" of 2, it will kick on at 72, and cool till 68, then wait till it gets larger again.
Thanks for your assistance. If you could point me to any resources related to this that would be great as well. Just trying to fully understand how a central air system in E+ is modelled.
