Re: [EnergyPlus_Support] Re: Zone controls and thermostats
You must add an HVAC system to control to the set point if the loads are
to be meaningful. I recommend using the Compact HVAC:Zone:Purchased Air
system and to also use the Compact HVAC:Thermostat object. These compact
HVAC objects make it much easier to set up the system.
