Sounds like a user issue.

As Thunder points out, the vent controls can be set regardless of what temperature you select. The vents are what people usually sense as the output of the HVAC system. If you are asking for 84 degrees as a hold temperature, while simultaneously instructing the vents to blow cold, (because you can) you will understandably create a situation whereby you are not getting a steady internal temperature, because the system can't figure out the competing instructions. This comes under the category of the system having two many knobs and adjustments for just about any user. Complexity rules.
