(2) Temperature of input-output water to/from source-side heat exchanger 10/7°C; temperature of input-output water to/from user-side heat ex
-
changer 40/45°C. Values compliant
with standard EN 14511
(4) Unit operating at nominal operating capacity, with no options of any kind, with source-side heat exchanger input/output water temperature of
10/7°C and user-side heat exchanger water inlet-outlet temperature of 40/45°C. Values obtained from measurements carried out in accordance
with standard ISO 3744.
(5) Values obtained from the sound power level (conditions: note 4), related to a distance of 1 m from the unit in free field with directivity factor Q=2.
Non-binding values.
(6) Theoretical values referred to the basic unit (without DC). The amount of gas actually charged in the unit may differ.
(7) Approximate value. The minimum capacity reached by the unit depends on the operating conditions. The value shown may not be suitable for
calculating the minimum volume of water: to do this, consult the “Minimum water content in the system” section.
** Basic unit without included accessories
