Performance figures relate to the following conditions:
(1) Cooling: external air temperature 35°C; intake/outlet water temperature 12/7°C.
(2) Cooling: external air temperature 35°C; intake/outlet water temperature 23/18°C.
(3) Heating: external air temperature 7°C d.b. 6°C w.b.; intake/outlet water temperature 40/45°C.
(4) Heating: external air temperature 7°C d.b. 6°C w.b.; intake/outlet water temperature 30/35°C.
(5) Sound level power: determined based on the measurements carried out in accordance with ISO 3744.
(6) Sound pressure at 1 m obtained in free field over a reflecting plane. Tolerance values ± 2 dB. Sound levels refer to the unit under
maximum operating conditions. The data refer to the operating conditions with outside air temp 35°C, water temp. 7/12°C.
NOTE
The stated performance data are guideline and may be subject to variation.
Furthermore, the yields stated in points (1), (2), (3) and (4) are to be understood referring to the instantaneous power according to EN
14511.

Blow are shown the head-flow rate curves net of hydronic kit pressure drop. Each curve shows the optimal operating point under the
conditions specified at the peak (4) of Chapter 13 “Technical data”.
The system must be designed in a manner which guarantees the nominal flow rates for the duty points specified below.
