Electrical data
Noise levels
Reference conditions
Performances referred to units operating in heating mode at nominal conditions A7W35.
Unit placed in free field on reflecting surface (directional factor equal to 2).
The sound power level is measured according to ISO 3744 standard.
The sound pressure level is calculated according to ISO 3744 and is referred to a distance of 1 meter from the external surface of the unit.
