1. TECHNICAL CHARACTERISTICS AND DATA
1.1 Introduction
Our unit is a high-efficiency heat generator for heating and hot water production running on natural or liquefied
petroleum gas (configurable at the time of installation) and regulated by an advanced microprocessor control
system.
The boiler shell consists of a copper laminar exchanger whose particular shape guarantees high exchange
efficiency under all operating conditions and an open-flue burner equipped with electronic ignition and ionization
flame control.
The boiler is totally sealed off from the installation room: the air needed for combustion is drawn from outside
and the flue gases are expelled by a fan. The boiler outfit moreover includes a variable speed circulator,
expansion tank, flow meter, safety valve, filler cock, air pressure switch, water pressure switch, temperature
sensors, safety thermostat and an antifreeze thermostat with the relevant heating elements.
Thanks to the microprocessor control and adjustment system with advanced self-diagnosis, unit operation is
for the most part automatic. The power for heating is automatically governed by the control system according
to the indoor and outdoor characteristics (with an optional outdoor sensor installed), the characteristics of the
building and of its location. The power for hot water is automatically and continually governed to ensure a fast
delivery and comfort under all operating conditions.
The display continuously provides information on the unit's operating status and it is easily possible to obtain
additional information on the sensor temperatures, set-points, etc. or configure them. Any operating trouble
associated with the boiler or system is immediately signalled by the display and, if possible, corrected
automatically.
