Is there a way to set a temperature dead band in OpenStudio?

I am trying to set up my heating and cooling setpoints to have a dead band range so that the HVAC system can potentially be turned on and off as needed, instead of being constantly on. However, when setting up a heating or cooling schedule, it appears that I can only set one static value.

For example, in the screenshot below, I set a cooling setpoint of 23.9C. I want a dead band of 1.1C, so I set the upper and lower limits as 22.8C and 25C. However, those limit settings seem to be only for display purposes. When I run the simulation, the zone temperature is still constant. Is there a way around this?

UPDATE: Temperature fluctuation is noticed when the building model is changed from three thermal zones to one. My original building model is made up of an unconditioned crawlspace, a conditioned main floor, and an unconditioned attic. The secondary model is made up of just the conditioned main floor. Both have exactly the same construction materials, but the indoor temperature (in blue) is almost steady in one but fluctuates between the setpoints in another.
