Ok have tried putting on high fan speed and monitoring the energy usage and were looking at 150watts less if its on high fan speed compared to if its on low fan speed. Still no where near the quoted ratings in the specs. My question is why doesnt the inverter ramp right down if it knows that the indoor is on low fan speed so as to not have to gather as much heat. Or is it using more power when the compressor is having to compress the vapour back into a liquid because it hasnt all turned back to a liquid due to it still retaining some heat? Or am i missing a point here?
