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
Hydro Insert when the ue
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 ue or
signi cant 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 Hydro
Insert and the display
will show “
A L A R - S I C -
F A I L
” . To restart you
need to reset manually.

WATER
Electrical safety:
the
Hydro Insert 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
Hydro Insert. Other fuses
to protect the electronic
boards are to be found on
the boards themselves.
Reduction motor:
if the motor stops, the
Hydro Insert continues to
function until the ame
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 Hydro Insert
and of the heating system.
Safety valve:
this valve
acts to prevent over
pressurization
of
the
hydraulic system.
If the pressure of the Hydro
Insert or plant exceeds 2.5
bar it drains the water
from the circuit.
Anti-freeze function:
if the probe in the Hydro Insert 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 Hydro Insert 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 Hydro Insert display.
