I noticed that only dual setpoint is available for "ThermostatSetpoint" in the Inspector in OpenStudio plugin for Sketchup.
So, how to define a single cooling/heating setpoint in Openstudio?
OpenStudio only supports ThermostatSetpoint:DualSetpoint. It does NOT support neitherThermostatSetpoint:SingleHeating nor ThermostatSetpoint:SingleCooling.
While it could be checking on forward translation to create a proper object, it just deletes the Thermostat altogether!
So if you have a heated-only zone you MUST input a cooling schedule as well: pick a high number, like 120°F/50°C.
If you have a cooled-only zone, you MUST input a heating schedule as well: pick a low number, like 32°F/0°C.

I added this functionality circa October 2017: see PR #2813. The ThermostatSetpointDualSetpoint in OpenStudio now behaves like this during the Forward translation:
Any version after 2.3.1 included will have this feature.
@finorths: yes, see my edit of the answer in response to your comment.
Not planned, no one has requested it in the past 10 years, and I don't have a good use case for it. But you can always open a feature request https://github.com/NREL/OpenStudio/is.... Try to explain carefully why you need the object, to make a case for it.

See this post, I think it will answer your question.
noted with many thanks, David!
So, a dual setpoint thermostat is required by default in OpenStudio even if the heating setpoint will not be used at all, right?
Correct. There may be a time when we support additional thermostat types, but for now we just support dual setpoint.
I feel like this is an important enough question that it warrants having an answer so I'm reopening it. I just came across this thread after running into problems of my own.
