Hi everyone,

I'm working with a model which VRF system. I'm using detailed HVAC, and I have set the heating and cooling setpoints to 18 and 28 degrees respectively. There is no natural ventilation in the model. Occupancy is always on. However, these setpoints are not always met. See some images below:

I'd like the operative temperature to adjust as accurately as possible to the heating and cooling setpoints once these are exceeded.

I have no constraint in terms of the settings of the VRF system; could anyone please tell me what can I change to meet these setpoints? Also, I have had similar problems when applying unusually higher cooling setpoints, such as 32 degrees.

Please, find attached the dsb and idf files.

Thank you very much in advance.
