Safety devices
ELECTRICAL SAFETY
The insert is protected against violent current changes by two fuses (4A 250V) inserted inside the master switch positioned on the right side of the insert
and another fuse (4A 250V) inserted inside the control unit.
SYSTEM OVER-PRESSURE SAFETY
The insert is equipped with a safety valve calibrated at 2.5 bar.
92°C WATER OVER-TEMPERATURE SAFETY
The insert is equipped with a water probe inserted on the bulb-holder well positioned on the upper part, which detects the temperature of the water.
If the temperature should reach 92°C, the probe indicates the alarm in the control unit.
"ALAR HOT H2O" will be shown on the display followed by an acoustic alarm.
During the alarm, the speed of the flue gas intake device is taken to maximum, the pellet flow is interrupted, switching the motor reducer off.
After 10 minutes the intake device also switches off.
WATER SAFETY PROBE FAULT
If the probe that detects water temperature should break or if the latter is disconnected, the display will show "ALAR SOND H2O" followed by an acoustic
alarm.
During the alarm, the speed of the flue gas intake device is taken to maximum, the pellet flow is interrupted, switching the motor reducer off.
After 10 minutes the intake device also switches off.
95°C WATER OVER-TEMPERATURE SAFETY
The insert is equipped with a manual/rearm thermostat positioned under the front panel, which intervenes if the water inside the insert should reach 95°C.
The manual rearm thermostat directly removes the power supply from the motor reducer making the insert switch-off.
In the event of over-temperature, the thermostat rearm is manual.
280°C FUMES OVER-TEMPERATURE SAFETY
The insert is equipped with a fumes probe inserted near to the fumes intake (right side), which detects the temperature of the outlet fumes.
If the temperature of the fumes should reach 280°C, the probe indicates the alarm in the control unit.
"ALAR HOT TEMP" will be shown on the display followed by an acoustic alarm.
During the alarm, the speed of the flue gas intake device is taken to maximum, the pellet flow is interrupted, switching the motor reducer off.
After 10 minutes the intake device also switches off.
FUMES SAFETY PROBE FAULT
If the probe that detects fumes temperature should break or if the latter is disconnected, the display will show "ALAR SOND FUMI" followed by an acoustic
alarm.
During the alarm, the speed of the flue gas intake device is taken to maximum, the pellet flow is interrupted, switching the motor reducer off.
After 10 minutes the intake device also switches off.
BLOCKED FLUE OR TOO ARTICULATED SAFETY
The insert is equipped with a fumes pressure switch, positioned on the right side and connected with a small pipe near to the fumes intake (right side),
which intervenes if the flue is blocked or too articulated (RESISTANCE FACTOR TOO HIGH)
The pressure switch directly removes the power supply from the motor reducer making the insert switch-off.
NO IGNITION
If the insert does not switch-on during ignition, the ignition cycle is repeated. If the insert does not switch-on after the second ignition cycle, the display will
show "NO PELL" followed by an acoustic alarm.
OPEN DOOR SAFETY DEVICE
the insert has a micro switch positioned on the door, which intervenes if the door is not closed well.
The micro switch removes the power supply directly from the motor reducer, making the insert switch off or not switch on during the ignition phase.
INSERT UNATTACHED SAFETY
the insert has a micro switch positioned on the rear of the boiler body, which intervenes if the front retainer is not attached well.
The micro switch removes the power supply directly from the motor reducer, making the insert switch off or not switch on during the ignition phase.
The fumes and water temperatures can be displayed during normal functioning, by holding key 1 down.
