WHAT HAPPENS IF...
...the thermo stove does not switch on
In case of no ignition, the
“NO FIRE”
alarm is displayed.
Hold button 4 (switch on/off) for a few seconds to restore the thermo stove to standard conditions (remove the alarm).
...lack of power for a few seconds
Once the power is restored, the thermo stove immediately restarts from the status it had before the power outage (recovering the set work power).
... lack of power
As soon as the power is restored after a power outage, the thermo stove sets on
“STOP FIRE”
mode and carries out the entire switch off cycle until its
cooling. Once this phase is completed, the thermo stove can be normally switched on to proceed working at the set power.
…the fire-door is open or closed improperly
In case the door is open or closed improperly, the motor reducer cannot be powered electrically, not allowing the thermo stove to switch on. If the thermo
door is opened during the normal operation, the thermo stove burns all the pellet in the brazier, activating the
“ALAR NO FIRE”
alarm (sudden switch off).
The flue is dirty, blocked or not manufactured correctly.
In case the flue is dirty, blocked or not manufactured correctly, the motor reducer cannot be powered electrically not allowing the thermo stove to switch on.
If the flue blocks during the normal operation, the thermo stove burns all the pellet in the brazier, activating the
“ALAR NO FIRE”
alarm (sudden switch off).
...the stove is overheated
In case of water over-temperature in the boiler, the message
“ALAR HOT H2O”
is first displayed followed by an acoustic alarm. At this point the motor
reducer is not electrically powered, because the rearm safety thermostat is activated. Therefore the thermostat must be rearmed before switching on the
stove.
