Hi, thank you very much for the reply. I should have clarified in my original post that I'm not using a curve-fit coil model but implementing a different model directly into EnergyPlus. It sounds like the EMS is my only option, so I will look into it and see if I can get the driftpoints to work there. Thank you again for the reply.

I'm working on a simulation in EnergyPlus and I'm trying to figure out how to set drift points/a dead band for a thermostat (i.e. if the thermostat setpoint is 74F and I want to let it drift to 75F before cooling turns on, whereupon it can cool down to 74 or maybe 73F). I've been reading the Input Output Reference and it looks like the thermostat I'm currently using (ZoneControl:Thermostat) doesn't have any capability for drift points. The thermostat control ThermostatSetpoint:DualSetpoint (which I'm using) has dual setpoints for heating and cooling (i.e. cooling turns on at 74F and heating turns on at 65F but between 74F and 65F nothing happens) but apparently not for drift points as I described above.

I did find ZoneControl:Thermostat:StagedDualSetpoint, which lets the user input a throttling temperature range (i.e. if the zone air temperature exceeds the setpoint by more than a set delta T (or throttling range), it will cool the air down below the setpoint by the set delta T, if I'm reading it right). However, that also calls for staged heating and cooling coils, which I am not using.

So, my question is: Is there a way to use controls or setpoints in EnergyPlus to model the above-mentioned drift points? Or is adding false "stages" to the coils and using ZoneControl:Thermostat:StagedDualSetpoint my best bet?
