Fixed it! I managed to significantly reduce my unmet hours to reasonable numbers. The issue in my case - which may not apply elsewhere - is that unmet hours for JV3 in Australia is defined by whether the AC is operating or not - i.e. air conditioning schedule. However, the occupancy schedule that we are required to use has occupants still in the building - albeit at a low occupancy - outside the air conditioning schedule. Which results in an "occupied" hour when the AC isn't allowed to run and can't control the temperature, resulting in an unmet occupied hour if the load is sufficient to bump it outside setpoint - not an unmet operating hour.
I fixed it by having a huge jump in my cooling and heating setpoints when the AC comes on and switches off. Thought this might help someone else down the track
