* Performance values refer to the following conditions:
Cooling: room air temperature 27.0°C DB RH 50%, ambient air temperature 35°C;
Heating: room air temperature 21.0°C DB, ambient air temperature 7°C DB / 6°C WB.    
** Noise level measured by adopting average value in the noise lab with background noise of 25 dB (A), at a distance of 1.5m high fan speed.
