"Inverter" was written on the IDU as well as the ODU. Additionally, I checked the model number in Daikin's website and found it to be a R-22 based inverter model.
Since the ODU was installed in the balcony (balcony could be accessed), I saw the fan turning off. Additionally, with the fan (ODU) turned off, the ODU was absolutely silent- I stood in front of it and could hear absolutely no sound or feel any vibrations. So, I am assuming that the ODU would have shut off completely. All my observations are based on the "cool operating mode" set at 24C temperature on a sunny afternoon.
