Start-up
To switch on the boiler, keep the “B” (ON) key on the panel pressed. The boiler starts an ignition procedure that brings the ame to a
suitable level to Supply Power.
Supplying power
The power supply of the boiler is indicated by “power level bars”: one bar corresponds to minimum power, 5 bars to maximum power;
this level is determined by the heating system heat requirements, the boiler adjusts pellet loading parameters, fumes extraction, and
combustion air ow to comply with this requirement.

In the MENU screen, move the cursor with arrows“C”-”D”and select PROGRAMS, press ok“E”to conrm. Next select the programme you
wish to set.
Once completed, always press “ACTIVATE” to conrm the choice of programme.
The TIMER 1 and 2 programs are freely programmable for each 1/2 hour of the day on three dierent temperature indicators (T1-T2-T3)
and in dierent ways for each day of the week.The OFF level requires that the boiler is switched o in that interval.
Example of temperature programming for Monday.
Select the TIMER 1 item from the PROGRAM menu and press the ENTER “E” key, using arrow“D”highlight Monday and press OK (“E”) to
enter programming.
Using the centre arrow keys “C” and “D” select the half hour interval to be selected and use the “E” key to set the temperature T1-T2-T3
(depending on whether the key is pressed 1-2-3 times, the corresponding temperature can be read in the bottom right of the display).
Once temperature programming for Monday is complete press the ‘’B’’ SALVA (SAVE) key. If the same temperature scale of Monday is
desired for other weekdays, after saving (“E” key) press the “C” key (COPIA-COPY), select the day where the programme is to be copied
using the“D”key and press the“C”key (INCOLLA-PASTE). Repeat the same procedure until the programmes for all weekdays are complete.
At this point the boiler is programmed according to your temperature needs, which can be modied at any time.
ATTENTION:
In order to facilitate using the boiler, RED provides Timer 1 with preset weekly temperatures and times (according to the table below),
whereasTimer 2 is empty. In any case, it is possible to change times and temperatures ofTimer 1 at any time.
PANEL OFF DISPLAY FROM TIMER
When timer 1 (for example) has no set temperature, the panel highlights that the boiler is in OFF.
If the boiler is o from the MANUAL command, the
timer will have no eect.
For the boiler to come on with the timer, the panel
must display the image shown on the side; if this
should not be the case, it may be necessary to press
the ON (“B”) key.

MANUAL
This function can be activated from the menu PROGRAMME by pressing the key“C” ACTIVE. When this function is activated, the boiler no
longer follows time programming of TIMER 1 or 2 programs, but it keeps the temperature set in the main screen throughout the 24-hour
time period. It is possible to switch to programmes at any time.
TEMPERATURE LEVELS
It is possible to change the 3 temperature levels referenced by timers in this menu.
From the PROGRAMS menu use arrow key “D” to move and select TEMP LEVELS, press the “E” key, and enter the temperature settings
screen. Choose which temperature you want to set: AMBIENT or DELIVERYWATER.
With the centre arrow keys “C”and “D”, it is possible to increase/decrease the temperature value, while the “B”key is used to move to the
next temperature. With the“E”key (OK), the set values are conrmed.
SLEEP FUNCTION
The sleep function is only activated when the boiler supplies power and makes it possible to programme a boiler shut-o time. Shut o
can be delayed up to a maximum of 8 hours from current time and with a 10-minute resolution.
To activate, enter the PROGRAM menu, scroll using arrow key“D”up to Funct. SLEEP press the ATTIVA (ACTIVATE)“C”key. In the next screen,
using keys“C”and “D”, increase or decrease the minutes (10 minutes each time the key is pressed) and press OK (“E”key) to conrm the
boiler shut o time.
NOTE: If the boiler is not supplying power the display shows the wording“NOT AVAILABLE”.

PELLET RECIPE
This function is for adapting the boiler to the type of pellet in use. As there are many types of pellet available on the market, boiler
operation can vary considerably according to the quality of the fuel. When the pellets clog up the brazier due to excess loading of fuel,
vice-versa if the ame has a tendency to shut-o, it is possible to decrease/increase the amount of pellets in the brazier:
The available values compared to factory settings are:
+15% +10% + 5%; 0%; -10% -20% -30%
To modify the pellet recipe, in sequence, press:
from the Settings menu- press ok (E key), press the D key (arrow key) scroll up to pellet recipe and press OK (E key) and enter the function,
using the“C”and“D”keys to modify the parameter and press Ok (“E”key).
ACTIVE +
The pellet type is not a problem because the stoves are equipped with the Active system and automatically adapt to pellet of any length
with a diameter of 6-8 mm. Eective and ecient combustion is independent from any type of connection to the ue which, with
traditional systems, may constitute a problem during the installation phase.
Thanks to an internal sensor, the boiler is extremely reliable and precise, combustion air is constantly adjusted based on the quantity of
pellets present in the brazier, thus guaranteeing an eective and ecient combustion that is translated into decreased consumption,
emissions, and less frequent cleaning.
Thanks to Active plus, it is possible to control and communicate with the boiler, even by way of Smartphone and tablet. Since it is possible
to manage more evolved gear motors (with continuous operation), the new pellet stoves equipped with active plus are more silent.
This function is used to adjust combustion air if the ame is too high or too low.
It can be activated from the SETTINGS menu, scroll using the“D”arrow key up to the“Ricetta Aria”(Air recipe) function, press OK using the
“E”key, and, using the“D”arrow key modify the parameter and press“ok”“E”key.

Note:The storage cylinder probe/thermostat choice implies the three-way aux output designation.
The puer probe/thermostat choice implies the pump aux output designation.
• Room Therm.2
The boiler heat request may take place from any part of the room probe or from the “Termostato Amb 2”(Room thermostat 2) installed
in a room that is dierent from the one where the boiler is positioned and is connected to terminals 1 and 2 of the back terminal board.
Closing the contact of the terminals kicks o the heat request.
Notes: Installation of this thermostat is optional, the boiler can also operate without it. Since the contact is N.O., the room probe is the
only heat request command.
Possible active weekly programming does not act on Room Thermostat 2 but rather on the probe on board the boiler.
Attention! The room input contact (terminal board contact 3-4) leaves the factory jumpered, so as to always have
heat request from heating.
When installing room probe or thermostat, remove the jumper (see page 22 “puer thermostat”).

• External probe
It makes it possible to work with system temperature adjustment. If installing an external probe on terminals 1 and 2 (NTC 10KOhm at
25°C b=3435) water temperature is automatically calculated by the electronics based on external temperature according to the curves
shown below:
The external probe must be installed on an external wall exposed towards North or North-West. If necessary, it is possible to correct the
value read by the probe by + 5 -5°C.
• Storage cylinder probe
To activate this option, connect a probe (NTC 10KOhm at 25°C b=3435) to points 1 and 2 of the back 9-pole terminal board.
The heat request occurs when the storage cylinder probe reads a temperature that is 2°C below the one set by the accumulation
temperature marked by a tap in the temperature menu.
In this conguration the 3-way valve must be connected to contacts 10-11-12.
• Storage cylinder thermostat
To activate this option, connect a Normally Open (N.O.) contact thermostat to points 1 and 2 of the back 9-pole terminal board.
The heat request occurs when the storage cylinder thermostat closes the contact.
In this conguration the 3-way valve must be connected to contacts 10-11-12.
• Puer probe
To activate this option, connect a probe (NTC 10KOhm at 25°C b=3435) to points 1 and 2 of the back 9-pole terminal board.
The heat request occurs when the storage cylinder probe reads a temperature that is 2°C below the one set by the accumulation
temperature marked by a radiator in the temperature menu.
During installation with the puer, boiler operation is only and exclusively determined by the puer probe and not by the room probe.The
room probe on the boiler is only to control the heating system pump controlled by the NO potential-free contact: if the system pump is
activated in Aux out mode (max 5 ampere, not suitable for brushless pumps with upper start-up current) on terminals 8-9.
