SAFETY DEVICES
The product is supplied with the following safety devices
AIR PRESSURE SWITCH
Monitors pressure in the smoke duct. It is designed to shut down the pellets feed screw in the
event of an obstructed flue or significant back-pressure (wind).
WATER PRESSURE SWITCH
If water pressure drops below 0,2 bar in the circuit, stove is not operated to protect the
product and the pump being fired without water.
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, there by enabling start-up or stopping the product
when the temperature drops below the preset value.
CONTACT THERMOSTAT IN THE BOILER
If the temperature exceeds the preset safety level, it immediately shuts down stove operation.
WATER TEMPERATURE PROBE
If the water temperature approaches the shutdown temperature (85°C) the probe makes the
boiler perform the “OFF Stand-by” automatic shutdown.
ELECTRICAL SAFETY
The product is protected against sudden current surges by a main fuse in the power supply
panel on the rear part of the product. Other fuses that protect the electronic boards are found
on the latter.
SMOKE FAN
If the fan stops, the electronic board promptly shuts off the pellets supply and an alarm
message is displayed.
GEAR MOTOR
If the gear 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
If the power cut lasts less than 10" the stove returns to its previous operating status; if it lasts
more it carries out a cooling/restart cycle.
FAILED START-UP
If during ignition no flame develops, the boiler will go into alarm condition.
ANTIFREEZE FUNCTION
If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is
automatically activated to prevent 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
prevent it from seizing up.
