Safety devices
ELECTRICAL SAFETY
The thermo stove is protected against violent current changes by two fuses (4A 250V) inserted inside the master switch positioned on the rear of the
thermo stove and another fuse (4A 250V) inserted inside the control unit.
SYSTEM OVER-PRESSURE SAFETY
The thermo stove is equipped with a safety valve calibrated at 2.5 bar.
92°C WATER OVER-TEMPERATURE SAFETY
The thermo stove 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 thermo stove is equipped with a manual-rearm thermostat positioned on the rear, which intervenes if the water inside the thermo stove should reach
95°C.
The manual-rearm thermostat directly removes the power supply from the motor reducer making the thermo stove switch-off.
In the event of over-temperature, thermostat rearm is manual.
280°C FUMES OVER-TEMPERATURE SAFETY
The thermo stove is equipped with a fumes probe inserted near to the fumes intake (left 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 thermo stove is equipped with a fumes pressure switch, positioned on the left side and connected with a small pipe near to the fumes intake (left 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 thermo stove switch-off.
OPEN DOOR SAFETY DEVICE (pellet side)
The thermo stove has a micro switch positioned on the door of the pellet side, which intervenes if the door is not closed correctly.
The micro switch removes the power supply directly from the motor reducer, making the thermo stove switch off or not switch on during the ignition phase.
NO IGNITION
If the thermo stove does not switch-on during ignition, the ignition cycle is repeated. If the thermo stove does not switch-on after the second ignition cycle,
the display will show "NO PELL" followed by an acoustic alarm.
NO WATER LEVEL
The thermo stove has a level switch, positioned in the top part of the boiler body, which signals "no H2O" on the display at the moment when the water
inside the thermo stove does not reach a level sufficient to cover the copper heat exchangers.
When the following alarm is displayed, the upper majolica must be removed along with the lid in order to verify that the water inside the boiler body is at a
level such to cover the exchangers completely.
If the water is not at the correct level, it is good practice to open the cock on the right side in order to restore the water inside the boiler body. It is
recommended to close the cock.
The fumes and water temperatures of the pellet side can be displayed during normal functioning, by holding key 1 down.
However, it is possible to display the temperature of the fumes of the wood side during normal functioning, by holding key 2 down.
