(1) Source-side heat exchanger inlet/outlet water temperature 30/35°C; user-side heat exchanger inlet/outlet water temperature 12/7°C. Values com
-
pliant with standard EN 14511
(3) 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.
(4) Unit operating at nominal operating capacity, without any accessories, with source/side heat exchanger inlet/outlet water temperature 30/35°C
and user/side heat exchanger inlet/outlet water temperature 12/7°C.Binding values. Values obtained from measures taken according to standard
ISO 3744 and to the Eurovent certification programme where applicable.
(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.
(8) Reference to IS16590:2017, user-side heat exchanger outlet temperature 7 °C. Source-side heat exchanger inlet temperatures : part load 100 -
W39°C; part load 75 - W32°C; part load 50 - W26°C; part load 25 - W20°C.
(9) Reference to AHRI 550/590, user-side heat exchanger outlet temperature 6.7 °C. Source-side heat exchanger inlet temperatures : part load 100 -
W 35°C; part load 75 - W 26,7°C; part load 50 - W 18,3°C; part load 25 - W 12,8°C.
(10)
Former Eurovent’s seasonal efficiency index. Value not certified by Eurovent from 2019. Reference: base unit, without any accessories
** Basic unit without included accessories
