- Make sure to check the pellet level in the hopper so that the flame does not go out due to lack of
pellets.
- Make sure the unit is off when loading pellets.
- The pellet hopper lid must always remain closed; it must only be opened when loading fuel.
- The bags of pellets must be kept at least 1.5 m from the stove.
4.4.1 Modifying the water temperature setting
To modify the water temperature, press button P1 and then increase or
decrease the temperature parameter with buttons P1 and P2.
When the water temperature has reached the set value, the power is
automatically brought to the min. value, MODULATION status.
Want to change the room temperature is necessary to continue with the
SET button and then increase or decrease the temperature parameter
with buttons P1 and P2
When the fume temperature reaches a set max. value the message
'MODULATE F' appears on the control panel and the stove activates
the flame modulation procedure without any user intervention, whereas
if the temperature exceeds 285°C the alarm 'AL3 HOT FUMES'
appears and the stove activates the shutdown procedure.
4.4.2 Cleaning the brazier
During normal operation in work mode, the 'BRAZIER CLEANING'
mode is activated at fixed intervals for a set duration.
4.4.3 Water heater with storage tank
To modify the temperature it is necessary to press button P2 on the control panel and then increase or decrease the
temperature value with buttons P1 and P2.
The DHW function is activated when the temperature falls below the SET temperature. During the STANDBY phase,
the stove automatically lights and goes to WORK mode. Once the work temperature of the heating chamber water is
reached, the supply of water to the storage tank (puffer) is activated. The stove display shows the message DHW
and the respective LED lights up.
When the SET temperature of the storage tank is satisfied, the STOVE activates the heating system. If there is no
further demand, the stove goes on STANDBY or to MODULATION, depending on the settings (see par. 4.6.2).
If the stove is in OFF status, it does not light and does not provide the service.
4.4.4 System with puffer / heat storage
This type of installation requires the use of an external thermostat or a water probe, which measures the puffer water
temperature.
In the former case, temperature SETTING is obtained by adjusting the puffer thermostat controller.
In the latter case, to modify the temperature it is necessary to press button P2 on the control panel and then increase
or decrease the temperature value with buttons P1 and P2.
When the temperature drops below the SET external thermostat temperature:
If the stove is in the AWAITING REQUEST stage, it automatically turns on and goes to WORK status and the supply
of water to the puffer is activated when the work temperature of the heating chamber water is reached.When the
puffer SET temperature is met, the stove goes to AWAITING REQUEST (make sure to set the STANDBY function to
ON, see par. 4.6.2 ).
If the stove is in OFF status, it does not turn on and does not provide the service.
It is possible to choose the temperature SETTING of the DHW storage tank and of heating from a min. of 54°C (STD
pump start value) to a max. of 70°C with minimum return temperature not lower than (50-55)°C in order to prevent
condensation inside the chamber.
