DESCRIPTION
The cooker is off
The coil pre-heating phase has started and the pellets start to fall
into the brazier. The pellets ignite and take advantage of the heat
in the intake air that passes through the incandescent coil tube
The cooker has completed the switching-on phase and works at
the set capacity.
The desired room temperature is reached.
The periodic cleaning of the brazier is in progress (it does not turn
off the cooker).
With Climate Comfort active, the cooker switches to automatic
switch-off mode when the room temperature set is reached (see
the dedicated section).
The cooker is in the switch-off phase and the cooling phase has
not been completed yet.
The external thermostat requests the switching-off of the cooker,
if the latter is on, or keeps it off.
The external thermostat requests the switch-on of the cooker, if
the latter is off, or keeps it running, if already on.
Cooker switch-on is requested but with the cooker in cooling pha-
se; once this condition is met, it restarts automatically.
The HOT restart phase is activated.
Functioning is similar to the SWITCH ON phase
The maximum fume temperature threshold has been reached.
To facilitate cooling, the cooker brings the power to a minimum
with ventilation at power level 5, leading to a decrease in fume
temperature.
When the switch-on request from ECO-STOP mode coincides
with an automatic switch-off condition (from TIMER), the cooker
turns on ensuring total cleaning of the brazier before switching to
FINAL CLEANING.
CONDITION: pellet setting (set pellets +5) is near the continuous
load condition.
SOLUTION: Set the value back to 0.
