The values are referred to units without options and accessories.
Data declared according to EN 14511:
EER (Energy Efficiency Ratio) = ratio of the total cooling capacity to the effective power input of the unit
COP (Coefficient Of Performance) = ratio of the total heating capacity to the effective power input of the unit

* The factory refrigerant charge allows a maximum length of the refrigeration lines of 15 meters. The maximum length of the refrigeration lines is 30 meters: in this case it is necessary to integrate the charge during
installation.
** : SWL = Sound power levels, with reference to 1x10-12 W with unit operating in conditions:
A7W35 = source : air in 7°C d.b. 6°C w.b. / plant : water in 30°C out 35°C
A7W55 = source : air in 7°C d.b. 6°C w.b. / plant : water in 47°C out 55°C
A35W18 = source : air in 35°C d.b. / plant : water in 23°C out 18°C
A35W7 = source : air in 35°C d.b. / plant : water in 12°C out 7°C
Max = at maximum conditions in heating / cooling mode
Sil. 1 = if silent level 1 active in heating / cooling mode
Sil. 2 = if silent level 2 active in heating / cooling mode
The Total sound power level in dB(A) measured in compliance with ISO 9614 standards.
