Safety Devices - Cadel Thermostove 28 Manual De Instrucciones

Safety devices

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- FA IL A L A R- D E P- FA IL" " .
RESTART
WATER
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
thermostove and the display
will show " " AL AR- SIC-
AL AR- SIC-
FA I L" " . To restart you need to
FA I L
reset manually.
Anti-freeze function: if the probe in the thermostove 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 stove 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 stove display.
Reduction motor:
if the motor stops, the
thermostove continues to
function until the flame goes
out for lack of fuel, and until
It has cooled down to the
minimum level.
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
thermostove when
flue gas temperature drops
below the preset value.
Automatic vent valve: this
valve eliminates the air inside
the thermostove and of the
heating system.
Electrical safety:
stove is protected against
violent surges of current (ex.
lightnings) by the main fuse
4 A which is located on the
the control panel at the rear of
the thermostove. Other fuses
to protect the electronic
boards are to be found on
the boards themselves.
Safety valve: this valve acts
to prevent over pressurization
of the hydraulic system.
If the pressure
thermostove or plant exceeds
2.5 bar it drains the water
from the circuit.
