OPERATING BY ROOM THERMOSTAT
In compliance with current standards in
terms of energy saving, the device must be
connected to a room thermostat for optimal
temperature adjustment and maintenance
in domestic environments.

SPECIAL FUNCTIONS
FAULTS
CH Anti-Frost function
The anti-frost function is always active and
prevents the CH system water from freezing.
In the CH water temperature probe detects
a too low temperature, the circulator is
activated and the burner ignites at the
minimum power. The functions remains
active until a preset temperature (30°C)
is reached which prevents the CH system
water from freezing.
All functions supported by the boiler are
managed by a microprocessor-based system
which, aside from allowing the system to run
perfectly in order to maintain the greatest
level of comfort possible, constantly monitors
the functional parameters, ensuring they fall
within the necessary safety interval by a wide
margin, and therefore that all devices present
are functioning perfectly.
Whenever the malfunction of any component
or conditions which could compromise safe
operation of the system are detected, the
microprocessor system places the device into
a limited operation mode or even completely
prevents it from operating. The microprocessor
system is able to detect and issue warnings for
the main fault conditions to allow the system to
be brought back to normal conditions as soon
as possible. Fault warnings are given on the
LCD display. The malfunction is detected and
an intermittent warning displayed immediately,
consisting of a number preceded by the “E”
error symbol (Pict. 7). Faults are displayed on any
screen of the main menu.
Conditions causing transitory faults are possible.
Many of these are recognized and cause a
temporary block which is automatically reset
once the condition causing the fault has
stopped. Some of these provide for the possibility
to attempt to restore operation manually.
IF THE UNIT IS EXPECTED TO WORK IN VERY COLD ENVIRONMENTS, ALWAYS KEEP
THE SYSTEM POWERED ON WITH ALL THE SHUT-OFF VALVES BEING LEFT OPEN.
THIS FUNTION DOES NOT FULLY PROTECT THE UNIT AGAINST FREEZING, SINCE IT
DEPENDS ON CONTINUOUS POWER SUPPLY AND GAS SUPPLY.
ASK YOUR AREA INSTALLER FOR INFORMATION ABOUT CONFIGURING THE UNIT
INORDER TO PROTECT IT FROM VERY COLD TEMPERATURE.
