SAFETY DEVICES
The product is supplied with the following safety devices:
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the smoke temperature drops below the
preset value.
PELLET HOPPER TEMPERATURE PROBE
If the temperature exceeds the preset safety value, it immediately stops the product, which must cool down before the probe is restored
and the product restarted.
BOILER TEMPERATURE PROBE (ALARM A18)
If the water temperature reaches the shutdown temperature (95°C) the product switches off.
WATER TEMPERATURE PROBE (ALARM A17)
When the water temperature reaches 80°C the product gradually starts to decrease its power to 85°C. If 85°C are exceeded there is a safety
shutdown; the product restarts when the structure has cooled down sufficiently.
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 FAULT
If the fan stops, the electronic board promptly blocks the supply of pellets and the alarm is displayed.
GEAR MOTOR FAULT
If the gear motor stops, the product continues to work until the minimum cool level is reached.
TEMPORARY POWER CUT
If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then restarts.
FAILED START-UP
If no flame is developed during start-up, the product will go into alarm status.
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 1 minute every 24 hours to prevent it from seizing up.
IT IS FORBIDDEN TO TAMPER WITH THE SAFETY DEVICES.
The product can be started-up and the automatic function of the probe restored only after having eliminated the cause that
triggered the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene
according to the alarm message displayed on the product.
