EnergyPlus Dual Thermostat Set point
I have a fairly simple question about the Dual thermostat schedules in EnergyPlus simulation.
I am trying to make some changes to the default schedule set points and learn the effects for several months in an year.
I am wondering how EnergyPlus decides which schedule to use? For instance, if I want to run the simulation in month of May, whether the EPlus takes the cooling set point only for the calculation? So my question is whether EPlus takes heating set point for some winter months (Jan-April) and then cooling set points for summer months (May-October) and again the heating set point for November and December? Something like this or is the calculation measures are entirely different?
In other words, if I am doing a simulation for the month of April, which setpoint schedule it takes? Heating, Cooling or takes both and calculates the set point from that?
Thanks in advance and any suggestion would be great.
Thanks Albert Thomas
