1. OPERATING INSTRUCTIONS

1.1 Introduction

Dear Customer,
Thank you for choosing the FERSYSTEM TECH 31 C, a FER wall-mounted boiler of the latest generation,
featuring advanced design and cutting-edge technology.
FERSYSTEM TECH 31 C is a high-efficiency condensing pre-mix appliance for heating and hot water
production with extremely low emissions, running on natural gas or LPG.
The boiler consists of an aluminium laminar heat exchanger providing effective condensation of the
water vapour contained in the flue gases, permitting extremely high efficiency.
Above the heat exchanger, in the boiler, there is a pre-mix burner, with a large ceramic surface, equip-
ped with electronic ignition and ionization flame control, which achieves extremely low emissions while
ensuring high reliability and long life operation.
The boiler is totally room sealed from the installation room: the air needed for combustion is drawn from
outside. The boiler also includes a modulating speed fan, modulating gas valve, pump, expansion vessel,
safety valve, flow sensor, temperature sensors, a safety thermostat and a low water pressure switch.
Thanks to the twin 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.
The user only has to set the temperature desired inside the home by means of a room thermostat and
appliance temperature control. The adjustment and control system will provide optimum operation
throughout the year.
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 problems associated with the boiler or system is immediately signalled by the display and, if
possible, corrected automatically.
