CONTROL INTRODUCTION

Control introduction
FreeStyle
™ boiler is a high-efficiency condensing pre-mix ap-
pliance for central heating and hot water production, running
on Natural gas or Liquefied Petroleum (Propane) gas, generating
extremely low emissions.
The boiler is constructed with a stainless steel heat exchanger
providing effective condensation of the water vapor contained
in the flue gases, permitting extremely high efficiency.
Inside the boiler there is a premix burner with a large stainless
steel surface.
The boiler is sealed from the installation room: the air needed for
combustion is drawn from outside. The boiler also includes a gas
valve, pump, (Combi boiler), safety valve, flow sensor, (Combi
boiler) dual safety and control temperature sensor, a safety ther-
mostat and a low water pressure switch.

user s information manual
Thanks to the microprocessor control and adjustment system
with advanced self-diagnosis, unit operation is for the most part
automatic. The system heating temperature is automatically
governed by the control system.
The display continuously provides information on the unit's
operating status and it is easily possible to obtain and adjust
temperature set-points, etc. or configure them. Any operating
problems associated with the boiler are immediately signalled by
the display and, if possible, corrected automatically.
