OPERATING PHASES OF THE APPLIANCE
Sequence of ignition phases
SWITCH-ON - initial pellet loading phase;
WAIT FLAME - flame development wait phase;;
FLAME PRESENT - flame stabilization phase and reduction of combustible inside the brazier;
WORK - operation phase described in the dedicated chapter;
Modulation
During the work phase, the appliance should reach the room temperature set; when this condition is met, the stove switches to MODULA-
TION mode in which fuel consumption is minimum.
📌
When the set room temperature is reached, the stove goes into Modula mode and the pump switches off. In the event of an
increase in the water temperature, the pump is automatically reactivated.
Eco stop
With the “COMFORT CLIMA” function activated, the stove switches off when the room / water temperature set has been reached.
With the “Summer” season set, the stove switches off when the DHW (boiler) temperature has been reached.
Stand-by
The STAND-BY mode is activated when the temperature of the water reaches 85°C, this function is aimed at protecting the circuit
especially when COMFORT CLIMATE function is not active on boiler H2O. If the boiler is not in this condition , it switches to STAND-
BY mode to guarantee protection of the hydraulic circuit. The boiler restarts automatically after it cooled down, on the condition that
heating is requested.
Sanitary
If there is an external rapid exchanger with flow switch, when the domestic water is opened the stove goes to “Sanitary” power. This
function is enabled only with scheme 0. If the stove is off, it remains off.
