Re: [EnergyPlus_Support] Re: Zone controls and thermostats



It looks like you are using a single cooling set point. Does your 
control type schedule have all 4's? 4 means dual set point. Your 
thermostat objects should look like this.

  ZONE CONTROL:THERMOSTATIC,
    MyTSTAT,                     !- Thermostat name
    YourControlZoneName,         !- Control zone name
