Re: [EnergyPlus_Support] Turning system on/off based on temperature predictions



This is certainly possible in E+. There are several ways to do this in 
E+. The control type schedule in the thermostat object could be used to 
switch between uncontrolled and cooling/heating, or the temperature set 
point schedule could be set to 0 and 99 as necessary to turn the unit on 
and off. The availability schedule could also be used in this same 
fashion by setting the schedule to 0 when you want the unit off and 
non-zero values when you want the unit on.  The AC system could turn 
full on or run at part-load depending on which method you decide to use.
