• BULB TEMPERATURE PROBE IN THE WATER TANK
If the temperature exceeds the preset safety level, it immediately
shuts down the running of the stove, and has to be reset manually
before the stove will restart
• WATER TEMPERATURE PROBE
If the temperature of the water approached shutdown temperature
(85°C), the probe causes the stove to go through a series of
cooling cycles or "ECO-STOP" automatic shutdown to prevent
blocking of the bulb temperature probe as described above.
• ELECTRICAL SAFETY
The stove is protected against violent surges of current by the
main fuse, which is located on the control panel at the rear of the
stove. Other fuses to protect the electronic boards (main board
and heat-exchanger board) are to be found on the boards
themselves.
• SMOKE FAN
If the fan stops, the electronic board shuts off the supply of pellets
in good time, and an alarm message is displayed.
• REDUCTION 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 OUTAGE
After a brief power outage, it automatically goes into cooling
mode.
• FAILURE TO LIGHT
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 teh
system from freezing.
•
PUMP ANTI-SEIZURE FUNCTION
If the pump is not used for prolonged periods, it is activated
periodically for 10 seconds to keep it from seizing up.
TAMPERING
PROHIBITED
Only after eliminating the cause of the intervention of the
safety is it possible to relight the stove and thus restore its
operation. To understand which anomaly has occurred,
consult this manual
to do based on the alarm message the stove displays.
