Low Specific Fan Power is the current industry buzz, but it requires some forward thinking to get and then keep your SFP's low.
The SFP (Specific Fan Power) of a fan coil is measured in W/(l/s). This is Watts per litre per second of conditioned air moved.
The Watts element of this formula is the Watts consumed by the motors alone. So while the controller and other electronic components on the unit may themselves take power, they should not and do not figure in the calculation.
