27-SAFETY DEVICES AND ALARMS

SAFETY DEVICES
The product is fitted with the following safety devices
ACTIVE +
Besides adjusting the stove operation, it also guarantees that the pellet loading auger is blocked if unloading or there is significant back
pressure.
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops
below the preset value.
CONTACT THERMOSTAT IN THE FUEL HOPPER
If the temperature exceeds the preset safety level, it immediately shuts down the running of the stove.
WATER THERMOSTAT
If the temperature exceeds the preset safety level, it immediately shuts down the running of the stove.
WATER TEMPERATURE SENSOR
When the water reaches the stop temperature (85°C) the probe automatically instructs the boiler to carry out
automatic "OFF Stand-by" shut-off.
ELECTRICAL SAFETY
The stove is protected against violent changes in current by a general fuse located in the control panel at the back of the
stove. Other fuses that protect the circuit boards are located on the latter.
SMOKE FAN
If the fan stops, the electronic board shuts off the supply of pellets in good time, and an alarm message is displayed.
GEAR MOTOR
If the reduction motor stops, the stove will continue to run until the flame goes out due to lack of fuel and until
a minimum level of cooling is reached.
TEMPORARY POWER CUT
When a power cut is less than 10" the stove returns to its previous operating state; if it is more, it executes a
cooling/re-ignition cycle.
FAILED START-UP
If during ignition no flame develops, the stove will go into alarm condition.
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 a few seconds to keep it from
seizing up.
