SAFETY DEVICES
The product is fitted with the following safety devices
PRESSURE SWITCH
Monitors pressure 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. (caused by wind)
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 boiler.
CONTACT THERMOSTAT IN THE BOILER
If the temperature exceeds the preset safety level, it immediately shuts down the running of the boiler.
WATER TEMPERATURE SENSOR
When the water reaches the stop temperature (85°C) the probe automatically instructs the boiler to turn off "OFF Stand-by".
ELECTRICAL SAFETY
The boiler is protected against violent changes in current by a general fuse located in the control panel at the back of the boiler. Other fuses
that protect the electronic boards are found 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 boiler 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 boiler returns to its previous operating state; if it is more, it executes a cooling/re-ignition cycle.
FAILED START-UP
If the fuel fails to ignite during the start-up phase, the boiler will go into alarm status.
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.
