I am trying to control HVAC states in EnergyPlus with more flexibility than the predefined thermostat. One example scenario is, in the simulation of multistage heating, my control logic would like to energize stage-1 heating only at some time point. Is it possible to do so in EnergyPlus?
My guess is that this may require a customized thermostat module that controls HVAC system via a set of pins/flags. But I did not find how to get it started in the tutorials. How shall I get it started?
