Safety devices
Water temperature probe:
if the water temperature
approaches the blocking
temperature (100 °C), the
probe requires to interrupt
the supply of pellets.
Flue gas temperature
sensor:
thermocouple that
measures the temperature
of the fumes while keeping
the operation or shuts the
boiler
when the flue gas
temperature
drops
below the preset value.
Pressure switch:
monitors
depression in the smoke
duct. It is designed to shut
down the pellet feed screw
in the event of an obstructed
flue or significant back-
pressure in the presence
of wind. At the time of the
pressure switch will show
“
A L A R - D E P - F A I L
”.
Safety thermostat with
manual reset for the
water temperature:
if
the temperature of the
water
tank
exceeds
the preset safety level
of 100 °C immediately
stops the operation of the
boiler
and the display will show
“
A L A R - S I C - F A I L
”.
To
restart you need to reset
manually.
Electrical safety:
the
boiler
is protected against
violent surges of current
(ex. lightnings) by the main
fuse 4 A which is located
on the control panel at the
rear of the
boiler
. Other
fuses
to
protect
the
electronic boards are
to be found on the boards
themselves.
Reduction motor:
if the motor stops, the
boiler
continues to function
until the flame goes out for
lack of fuel, and until It has
cooled
down
to
the
minimum level.
Automatic vent valve:
this valve eliminates the air
inside the
boiler
and of the
heating system.
Safety valve:
this valve
acts to prevent over
pressurization
of
the
hydraulic system.
If the pressure of
the
boiler
or
plant
exceeds 2.5 bar it drains the
water from the circuit.
Anti-freeze function:
if the probe in the
boiler
detects a water temperature of less than 5°C, the circulation pump
is automatically activated to keep the system from freezing.
Pump anti-seizure function:
if the pump is not used for prolonged periods, it is activated periodically for 10
seconds, to prevent it blocks.
Tampering with the safety devices is prohibited.
It is only after eliminating the cause which
gave rise to the intervention of the safety system, that it is possible to relight the
boiler
and thus
reset the automatic operation of the sensor. To understand which anomaly has occurred, consult
this manual at paragraph relating to alarms which explains what to do based on the alarm
message the
boiler
display.
