[. . . ] NEW ELITE Wall hung gas fired boilers with micro-storage heater for indoor installation NEW ELITE introduction FERROLI, in line with its position as a comfort multinational, one of the major players at a world level, permanently carries out research and trials on new products, so as to respond to the continuously evolving expectations of the users and the market. [. . . ] The appliances are factory set for semiautomatic mode, however the user can switch to automatic mode using the special button on the control panel. In addition, if the system needs to be filled to the required pressure (the recommended pressure is 1 bar), and the boiler is disconnected from the mains power supply, it can be filled completely manually (this mode is recommended for the first filling). L'elettrovalvola per il riempimento automatico/semiautomatico 3 NEW ELITE strong points CONTINUOUS FLAME MODULATION All models feature PID (that is, Proportional, Integral, Derivative) flame modulation, commonly known as the most evolved and technologically most advanced control system, which ensures maximum comfort in both central heating operation - and, above all - for the production of domestic hot water, as users now demand the maximum in terms of constant temperature throughout the delivery of hot water. In this regard, flame modulation in DHW production is based on two measurements: the temperature (using an electronic sensor) and flow-rate (using the flow meter). Outside probe COMPENSATION CURVE DIAGRAM "TEMPERATURE SCROLLING" AND CLIMATE CONTROL The NEW ELITE boilers are pre-fitted for "temperature scrolling" operation; that is, they are able to keep the outlet temperature at a minimum value, depending on the outside temperature. This operating mode can be activated by simply connecting the boiler to a special outside probe (optional). The automatic correlation between the two temperatures, outlet and outside, is the so-called "compensation curve". The user can choose, from the ten compensation curves available, the one that best suits the characteristics of the building and the radiators used, in order to achieve the maximum comfort with minimum fuel consumption.

REMO: THE REMOTE TIMER CONTROL The NEW ELITE boilers can connected to any type of room thermostat or timer-thermostat; if required, a modulating remote timer control (optional) can be used, with two-wire connection for remote control and daily/weekly room temperature settings.
