ECODESIGN AND ENERGY LABEL Tower Green HE Hybrid system: A+ class Tower Green HE Hybrid, together with a Hydronic Unit LE B heat pump, form a system in A+ class. According to the European Directive ErP, which came into force on 6.09.015, all products for central heating and domestic hot water production, with nominal output lower than or the same as 70 kw, must be classified through a proper Energy Label, showing the efficiency class. Besides the single "product label", the European rules foresee a "system label" in case of systems made of different appliances, components and relevant controls. Thanks to the virtuous synergy among the different components, the "system label" can achieve higher levels of efficiency than each relevant component. The compulsory labelling aims at giving the enduser the possibility to easily identify the efficiency of a product or a system, allowing a comparison with other products or systems with the same technology. As a consequence, also boilers will help to reach by 00 the "0-0-0" target, consisting in 0% reduction of gas emissions, 0% increase in the use of renewable energy and 0% reduction in global energy consumption within the EU countries.

It is possible to choose among different preset programs or to set a different customized program to suit your needs. 4

TECHNOLOGY AND ADVANTAGES Fixed point on cooling During the summer funcion in cooling mode, via heat pump, the flow temperature is fixed, with the possibility to choose different temperatures on the mixed zones. At the end of the demand on the direct cooling zone, in case of demand on the mixed zone, the control logic, that always pursues the maximum saving, provides that the cooling is produced at the right temperature, without need of corrections. The system allows to set one or more zones also in heating mode only, regardless of what is chosen on other zones. Therefore on these zones, in the summer function, cooling will not be produced. Sliding temperature on heating In the heating function both with the boiler and the heat pump, the flow temperature is "sliding", that is it is determined by the thermoregulation curve selected by the outdoor temperature. Heat pump integration on DHW The built-in DHW tank is heated by the heat pump and the boiler heat. The priority is on the heat pump, while the boiler covers the heat demand only in case the temperature probe asks its intervention. Frost protection and defrost function of the generator The boiler has its own logic in the management of frost protection (in case of non working heat pump) and defrost function (in case of working heat pump). Frost protection and defrost functions are protections conceived in order to preserve the generator in the energy saving perspective. Nightly attenuation It is also possible to program the nightly attenuation of the power of the heat pump to keep the noise level down to the wished values. 5
