CALIDO1
DHW heat pump with tank
34
NOTES:
* Heating capacity and power input detected in the following conditions:
ambient temperature 20°C, water temperature from 15°C to 55°C (these data are obtained by internal laboratory tests based on the uniform
reintegration of the tank temperature).
** Related to the auxiliary resistance. During the disinfection cycle, the temperature is raised to 70°C by the auxiliary resistance.
*** Energy efficiency of water heating based on ERP (EN 16147), profile L (200L) and XL (300L), Ambient temperature 7°C / 6°C, water tempera

**** Referred to tank with air temperature at 20°C and storage with water at 65°C.
(1) Technical label values referred to integration with boiler in accordance with DIN 4708 norms (primary 80/60°C, secondary 10/45°C)
(2) Measured according to EN 12102 standard in the conditions of EN 16147.
(3) Calculated according to ISO 3744:2010 algorithm at a distance of 1 m from the unit.
16. HEAT PUMP OPERATING LIMITS
It is recommended that the unit is operated within the following operating limits to avoid possible intervention of the protective devices.
In any case, for high temperatures (water temperature between 47 and 65°C, air temperature between 25 and 43°C), if the user sets a tempera
-
ture set outside the operating region, the heat pump automatically adapts its set to the limits shown in the diagram below.
