ENGLISH
Extraame has an optional additional board that allows the
boiler the following further functions when managing the
system. The table below indicates the various possibilities that
the optional can oer.
DHW Storage Management *
Puer Management *
3 heating areas *
Instant DHW option *
Puer pump or 4th heating area management *
Anti-legionella management for DHW storage *
DHW storage chrono management *
Auxiliary output management and control *
FUNCTIONING CYCLE 13.
BASIC INSTRUCTIONS13.1.
The following recommendations must be followed the rst times
the stove is ignited:
It is possible that slight odours are produced due to the
drying of the paints and silicones used. Do not remain in the
environment for long periods.
Do not touch the surfaces as they could still be unstable.
Air the room well several times.
The hardening of the surfaces is terminated after several
heating processes.
This appliance must not be used to burn waste.
IGNITION13.2.
ATTENTION!!!
DO NOT USE ANY INFLAMMABLE LIQUIDS FOR
IGNITION
DO NOT ALLOW THE BAG OF PELLETS TO COME INTO
CONTACT WITH THE BOILING HOT STOVE DURING
THE FILLING PHASE
IN THE EVENT OF CONTINUOUS NO IGNITION,
CONTACT AN AUTHORISED TECHNICIAN
Before igniting the stove, the following points must be veried:
the feed-box must be full of pellets
the combustion chamber must be clean
The burn pot must be completely free and clean
check the hermetic closure of the re door and the ash
drawer
make sure the power supply cable is connected correctly
The bipolar switch in the rear right part must be positioned on 1
Press key 1
P1
for 3 seconds.
If the machine has not ignited, the NO IGNITION alarm
occurs.
In the event of the alarm due to no ignition:
wait for the machine to cool down
Press key 1
P1
for 3 seconds.
WORK13.3.
The boiler will work to reach the water temperature set by the user
(see user menu). The pump will start to function as soon as the
factory-set parameters are reached. An always open heating area
is recommended to make the product functioning homogenous,
avoiding overheating blocks The boiler will automatically modulate
when approaching the temperature set, going to minimum power
and then switching-o (H OFF) if it will exceed the set over the
factory set-parameters. When the temperature of the water drops
within the factory-set parameters, the boiler will re-start.
Nota bene: the general times of the various functioning status
are variable on the basis of the type of system and on the basis
of the parameters set.
PUMP FUNCTIONING13.4.
The pump activates water circulation when the temperature of the
water inside the stove reaches approx. 60°C. As the pump always
functions above 60°, an always-open heating area is recommended
to make product functioning homogenous, avoiding overheating
blocks. Normally this area is dened “Safety zone”.
SWITCHOFF13.5.
Switch-o can take place manually by pressing key
P1
for three
seconds, automatically (due to a control programmed from the
utility in CHRONO mode), due to a contact of an additional external
thermostat satised or H OFF. i.e. temperature of the water reached
and exceeded.
When the operation has been performed, the appliance
automatically enters the switch-o phase, blocking the supply of
pellets; Display
D1
will show "OFF".
The ue gas exhaust motor will remain on until the stove
temperature has dropped below the factory parameters.
ADDITIONAL THERMOSTAT 14.
N.B. : Installation must be performed by an authorised technician
It is possible to thermostat a room adjacent to the room where
the stove is positioned: just connect a thermostat following the
procedure described in the next point (it is recommended to
position the optional mechanical thermostat at a height of 1.50m
from the ground).
The STBY function is always active from the factory (led
on) and the STBY clamp leaves jumpered (contact closed).
ADDITIONAL THERMOSTAT 14.1.
FUNCTIONING WITH STBY ACTIVE
When the contact or external thermostat is not satised (open
contact/temperature reached), the stove will switch o. As soon
as the contact or external thermostat passes to the "not satised"
status (closed contact/temperature to reach) it will re-ignite.
Nota bene: stove functioning depends on the temperature of
the water inside the same and relative factory restrictions set.
If stove is in H OFF (water temperature reached), any additional
contact or thermostat request will be ignored.
