To shut off the heater / boiler simply zero the power bars on the display.
DO NOT shut off the heater by disconnecting the generator from the electric power outlet. This operation could generate smoke that may not
be evacuated due to the construction characteristics of your system's smoke discharge tube and chimney.
The shut down time for the smoke exhaust is roughly 25 minutes.

The thermal value is adjusted through 2 buttons (1) and (2) described in para. 5.1.
5.12.1 COMBUSTION ADJUSTMENT IN MANUAL MODE (see para. 5.9.3 ).
5.12.2 COMBUSTION ADJUSTMENT IN AUTOMATIC MODE (see para. 5.9.4).
CAUTION: The manufacturer denies all responsibility for the life of the electrical heater if subjected to excessive start ups. It is
advisable, therefore, to set the correct power level to avoid this danger.
- Press the button (1) to begin the start up phase and the word START will appear on the display. Press the button (1) repeatedly to set the
appliance in AUTO or manual operating mode. The mode will be activated at the end of the start up phase. Press button (2) to adjust the
water temperature in the boiler that you wish to reach. During the 20 minutes of the start up phase any set thermal power level is ignored to
deal with correct fill up and suction values preset by the Manufacturer. The electrical heater will start to heat and after a few minutes the
first lot of pellets will start dropping into the brazier. This occurs because the screw feeder has to fill up because it is completely empty. The
first time the heater / boiler is started up the start up phase will have to be carried out twice for this very reason. Before beginning the
second start up phase empty and vacuum the brazier.
- Once again check the pressure inside the appliance and if necessary purge any existing air bubbles from the valve provided for this
purpose.
CAUTION: The start up phase (word START appearing on the display) takes approx. 20 minutes during which the heater / boiler
ignores any commands transmitted to it. After this time has elapsed the word RUNNING appears on the display.
When the machine is in the running phase the combustion can be adjusted manually or in AUTO mode.
CAUTION: The circulator pump begins operating as soon as the temperature in the boiler reaches 61°C.
CAUTION: If the appliance does not start up correctly check that the brazier and electric heater are clean. It is very important to
ensure that the tube lodging of the electric heater is clean; there must be no deposits or dust. This operation must be carried out
with a good vacuum cleaner.

ADDITIONAL ROOM TEMPERATURE THERMOSTAT / ADDITIONAL CHRONOTHERMOSTAT (not supplied)
The control panel ensures that your heater / boiler is provided with all the required programming and
temperature adjustment functions:
Two pairs of cable clamps are installed at the back of the heater / boiler near the power inlet. They
refer to two operating modes:
à
With the room temperature thermostat.
à
With the chronothermostat or modem.
Contacts 1-2 are defined as "CLEAN" contacts and they must never
be fed with 220 V. If the board is energised with 220V or with
voltages exceeding 6 V the control board will be permanently
damaged and will not be covered by the GUARANTEE.
When the external room temperature thermostat or the external room
temperature chronothermostat trips and switches on the generator,
the word EXT appears on the display (see figure on the right).
6.1 OPERATING WITH THE ADDITIONAL ROOM TEMPERATURE
THERMOSTAT (NOT SUPPLIED )
An additional room temperature thermostat can be installed by connecting it to the back of the heater / boiler, through a cable clamp inserted
in the socket labelled “THERMOSTAT” (see drawing in para. 5.2). .It has a clean contact, that is a low voltage contact. The operating principle
is as follows:
-
When the environment reaches the set temperature the thermostat closes the contact and the heater / boiler runs at the minimum
combustion power: the situation is described by the appearance of the 1st power bar on the display. Simultaneously, the circulator pump is
shut off and a few minutes later the symbol disappears from the display.
-
When the room temperature drops the thermostat opens the contact and the heater / boiler returns to its original position in terms of thermal
power.
