Failed ignition
If the system does not detect the ignition of the flame within the preset time, operation will be blocked with the “No ignition” alarm.
Before relighting the stove, check that there are pellets in the hopper, that the door and ash drawer compartment are closed, that there
are no obstructions to the combustion air inlet system and above all that, in models without self-cleaning brazier, the brazier is empty,
clean and correctly positioned. If the problem persists, it could be due to a technical problem (ignition plug, adjustments, etc ...), so plea-
se contact a Ravelli CAT.
⚠
The accumulation of unburned pellets in the brazier after a failed ignition must be removed before proceeding with a new
ignition.
⚠
The brazier could be very hot: danger of burns!
⚠
Never empty the brazier inside the hopper.
Setting operating temperature and power:
Set the two values following the indications given in the chapter “Description of the display”
OPERATING PHASES OF THE APPLIANCE
Sequence of ignition phases
IGNITION - initial pellet loading phase;
FLAME LIGHT - flame stabilization phase and reduction of combustibl e 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 MODULATION
mode in which fuel consumption is minimum.
📌
If you wish to detect the ambient temperature by means of an external thermostat (optional), this must be connected to
the appropriate connector on the rear side of the stove; and you will have to activate the reading in “SETTINGS - ENABLE
THERMOSTAT.” On display appears the writing TON / TOFF based on thermostat request.
⚠
Connect an external thermostat with a simple dry contact, therefore, not powered, moreover, we reccomend you use a
thermostat with a minimum offset of 3°C if you ntend to use the comfort clima function.

USING THIS METHOD, IT IS NECESSARY TO VERIFY THAT AFTER EACH AUTOMATIC SHUTDOWN
THE GRATE IS ALWAYS VERY CLEAN TO GUARANTEE CORRECT AUTOMATIC SWITCH ON.
AUTOMATIC SWITCH ON.
The first setting allows the activation of the CLIMATE COMFORT function. This function is intended to ensure that the room tem
-perature set is maintained steady upon setting the maximum period of “X” minutes (SWITCH-OFF DELA
Y: 5 MIN) before switch-ing to ECO STOP phase. The STOVE maintains this state until the temperature drops below the set
value (CLIMATE COMFORT DELTA : 5℃).
For example, with the room temperature at 21 ° C, the stove switches of f when this temperature is
reached and restarts when the temperature reaches 15°C (21°C - 5°C - 0,5°C tolerance).
You can also activate the function using an external thermostat, keeping in mind that this does not include the value of the hyster
-esis.
We recommend you use an external thermostat with a histeresys value that can be set to maximum 3°C.
The operation of the stove could activate the switch ON/OFF phases for several times during the day;
this may affect the service life of the ignition coil.

Chronothermostat
With the Chrono-thermostat function you can program the automatic switch ON/OFF of the stove for each day of the week
for each day of the week in 4 independent time intervals (SET CHRONO 1-2-3-4)
Below are given the steps for accessing the relative menu starting from Stand-By mode.

to quickly switch to
CRONO-THERMOSTAT.
By pressing the Increment key you can change each value and, at step 3, enable the days of the week;
By pressing the Increment key you can change each value and, at step 3, enable the days of the week;
Press “confirm” to confirm the settings and switch to the next value;
Press the “back” button to return to the CHRONO-THERMOSTAT page.
As per the above example, it has been set as CHRONO 1 an ignition from 08.30 to 21.30 from MONDAY to FRIDAY at the oper -
ating power 5 with a room temperature set at 21 ° C. Programmes 2-3-4 can be set in the same manner.
To exit the CHRONO-THERMOSTAT function and return to Stand-by page, press the button repeatedly.
AIR / PELLETS setting
Setting of the PELLET-FLOW mix enables you to immediately change the quantity of pellet loaded in the brazier and the air inflow.
The stove is tested and inspected with DIN PLUS certified pellets. If using another type of pellets or uncertified pellets, fuel may
need adjustment. Usually, the variation involves the FLOW percentage to adjust the input air and, therefore, the combustion; should
the regulation of flow be insufficient, it may be necessary to also change the percentage of PELLET load.
Below are given the steps for accessing the relative menu starting from Stand-By mode.
Press the key “access
menu” to access
the
MENU page
Press the key
“confirm”
to access the
USER page
Press the key
“selection”
to quickly switch to
SET AIR / PELLETS.
As per the above example, you have set a percentage of -2 for PELLETS and +3 for the FLOW , an indication
that a setting like this is a consequence of the fact that the oxygen needed for combustion is insufficient and pellet
size is smaller than the average size of 2 cm.
To exit the SET AIR - PELLET function and return to Stand-by page, press the button repeatedly.
NOTE: The number indicated during the change of parameters refers only to a percentage value that acts on the default
parameters set on the electronic board (exclusively in the WORK phase). These values should be changed in the event
of poor combustion, due in many cases to the purchase of pellets differing from those used during stove testing.

The TECHNICIAN and PRODUCER menus are password protected. Changing parameters within these menus could
compromise the operation and safety of the stove. In this case the warranty will be invalidated.
