water thermal head = 5°C
Min/max temperature Delta=3/8°C
ATTENTION: IN CASE OF PREDOMINANT WINDS, WINDBREAK BARRIERS ARE NECESSARY.
Data refer to unit operating with fans at max. flow-rate. It follows an energy efficiency increase, but also a sound pressure increase of about 2/3 dB(A).
(1) internal exchanger water = 12/7°C
(2) external exchanger air intake 30°C
Maximum exchanger inlet water temperature 32°C during max. 15 minutes, thanks to the variable flow rate device for the circulator (standard).

(3) Antifreeze (std)
(4) Data referred to still air
internal exchanger water = 40/45°C
Internal exchanger water outlet temperature=38°C
(6) room temperature = 7°C (RH = 85%)
(7) Minimum water temperature at exchanger inlet 14°C during max. 15 minutes, thanks to the variable flow rate device of the circulator (standard).
