NOTES:
* Capacity and power input based on 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 supplementary e-heater. During disinfection, the water temp could be up to 70°C by electrical heater
*** values referring to integration with boiler in accordance with DIN 4708 norms (80/60°C on primary circuit, 10/45°C on secondary circuit)
**** measured in free field at 1 m from the unit according to EN 12102 standard
