4. TEMPERATURE PROBES
The used temperature probes' features are given below.
4.1 Room/water temperature probe
The room/water probe used to measure water or room (in case of air stoves) temperature has the
following features:
IP67, NTC Thermoplastic probe: like NTC 10K ± 1% = 3435
Measuring field: -50/+120°C
Obtain a tester to check if probe is faulty, set it in ohm and measure the two probe pins (wire ends):
The probe measures about 10kohm at 25°C if it works correctly
If the probe is faulty: - resistance greater than 1Mohm (open)
- resistance to 0 ohm (in short)
The tester can also be used to check if the probe connection to the power board contacts are in short;
if 0 ohm resistance is measured by connecting the tester to the contacts, these are in short.
The lower display shows water (or room) temperature at 02°C if the room/water probe is not
connected to the power board. The display appears as in figure 10.

4.2 Pellet flue gas temperature probe
The flue gas probe used to measure the pellet's flue gas temperature has the following features:
Thermocouple probe: J type
Measuring field: 0/+350°C
Obtain a tester to check if probe is faulty, set it in ohm and measure the two probe pins (wire ends);
however, this only verifies if the probe is interrupted (no change compared to value shown on
unconnected tester).
The tester can also be used to check if the probe connection to the power board contacts are in short;
if 0 ohm resistance is measured by connecting the tester to the contacts, these are in short.
The upper display shows the pellet flue gas temperature (by pressing key 1) at 284°C if the pellet flue
gas probe is not connected to the power board. The display appears as in figure 11.

flue gas temperature if the wires' polarity is inverted.
4.3 Wood flue gas temperature probe (BI-FIRE MID –BI-FIRE wood side)
The flue gas probe used to measure the wood's flue gas temperature has the following features:
2 Wires PT1000 probe: PT 1000 class B
Measuring field: 0/+500°C
Obtain a tester to check if probe is faulty, set it in ohm and measure the two probe pins (wire ends):
The probe measures about 1k 1.1kohm at 25/30°C if it works correctly
If the probe is faulty: - resistance greater than 1Mohm (open)
- resistance to 0 ohm (in short)
The tester can also be used to check if the probe connection to the power board contacts are in short;
if 0 ohm resistance is measured by connecting the tester to the contacts, these are in short.

5. WHAT HAPPENS IF...
...the stove does not ignite
In case of no ignition, the “NO FIRE” alarm is displayed.
Hold button 4 (switch on/off) for a few seconds to restore the stove to standard conditions (remove the alarm).
...lack of power for a few seconds
Once the power is restored, the stove immediately restarts from the status it had before the power outage
(recovering the set work power).
... lack of power
As soon as the power is restored after a power outage, the stove sets on “STOP FIRE” mode and carries out
the entire switch off cycle until its cooling. Once this phase is completed, the stove can be normally switched
on to proceed working at the set power.
…the fire door is open or closed improperly
In case the door is open or closed improperly, the motor reducer cannot be powered electrically, not allowing
the stove to switch on. If the fire door is opened during the normal operation, the stove burns all the pellet in
the brazier, activating the “ALAR NO FIRE” alarm (sudden switch off). The flue is dirty, blocked or not
manufactured correctly.
In case the flue is dirty, blocked or not manufactured correctly, the motor reducer cannot be powered
electrically not allowing the stove to switch on. If the flue blocks during the normal operation, the stove burns
all the pellet in the brazier, activating the “ALAR NO FIRE” alarm (sudden switch off).
...the stove is overheated
In case of water over-temperature in the boiler, the message
“ALAR HOT H2O” is displayed first, followed by an acoustic alarm. At this point the motor reducer is not
electrically powered, because the rearm safety thermostat is activated. Therefore the thermostat must be
rearmed before switching on the stove.
...pellet insert unhooked or hooked improperly
In case the pellet insert is unhooked or hooked improperly, the motor reducer cannot be powered electrically,
not allowing the insert to switch on. If it is unhooked during the normal operation, the insert burns all the pellet
in the brazier, activating the “ALAR NO FIRE” alarm (sudden switch off).
6. ALARMS
The board intervenes and signals the occurred irregularity in case of functioning anomaly, operating in
different mode depending on type of alarm. The following alarms are foreseen in the board.
DISPLAY
ORIGIN OF ALARM
ALAR SOND H2O
Faulty or disconnected water temperature probe
ALAR HOT H2O
Water over-temperature. When water temperature exceeds 92°C
ALAR SOND FUMI
Faulty or disconnected flue gas temperature probe.
ALAR HOT TEMP
Flue gas over-temperature. When flue gas temperature exceeds 280°C
ALAR NO FIRE
No ignition. When flue gas minimum temperature (Pr13) is not reached within
maximum ignition cycle time (Pr01).
ALAR NO FIRE
Sudden switch-off during work phase. When, during work, the flue gas
temperature drops below minimum threshold (Pr13).
NO H2O
No water level. When water in boiler does not reach minimum level (only on
Sicuro Top BI-FIRE and BI-FIRE MID system)
Every alarm causes the equipment to immediately switch-off.
After time set on Pr11 (alarms delay) alarm state is reached; press key 4 to reset it.

7. FUNCTIONING PRINCIPLE
7.1 Ignition cycle
The ignition cycle can last max 18 minutes and is divided into three phases:
1 - FUN ASP : Intake device function
duration 8 seconds
2 - LOAD PELL : Pellet loading and resistance ignition
Pr01 = “LOAD PELL” duration
A pre-load phase may be present in “LOAD PELL” phase with specifications according to parameters Pr45,
Pr46 and Pr47.
3 -FIRE ON : Resistance switch-off and flame stabilising
Pr02 = “FIRE ON” duration
The stove goes to work phase at power set in ignition using buttons 1 and 2 after ignition cycle.

14
IGNITION PHASE

15
7.2 Work phase
The set work power or 1, 2, 3, 4, 5, SANI (optional) is shown on upper display during the stove's normal
functioning.
A “SET H20” (maximum temperature) can be set by working from Power 1 to Power 5. The stove enters
Functioning Economy “ECO-H2O” upon reaching of such set.
Before reaching temperature set on “SET H20”, the stove starts modulating power by decreasing pellet intake
and reducing flue gas intake device speed.
Example: “SET H2O” set at 75 °C
Work power set at 5
- The work power automatically changes to 4 upon reaching 71°C.
- The work power automatically changes to 3 upon reaching 72°C.
- The work power automatically changes to 2 upon reaching 73°C.
- The work power automatically changes to 1 upon reaching 74°C.
- The work power automatically changes to Functioning economy “ECO H2O” upon reaching 75°C.
The stove now automatically switches off if at least one of the following conditions exist:
If it remains in Functioning Economy “ECO-H2O” for a time set on Pr23 (120 minute default setting).
If it exceeds temperature differential set on Pr12 (10°C default setting) or H2O Temperature > (“SET
H2O” + Pr12)
With the following condition the stove automatically ignites:
If it drops below temperature differential set on Pr12 (10°C default setting) or H2O temperature < (“SET
H2O” –Pr12)
If the above-mentioned condition occurs when the stove is still carrying out the switch off cycle, it is required to
wait until it ends.

16
WORK PHASE

17
7.3 DHW power work phase
The domestic hot water is produced instantly via a double heat exchanger immersed in the water inside the
stove.
Therefore, the stove must be at temperature (60°C at least) to have domestic hot water.
Set stove in DHW power “SANI”if a large amount of domestic hot water is required.
The DHW power function “SANI”delays start-up of the heating pump at higher temperatures so that all heat
produced at such DHW temperature, is transferred.
Press SET to set the pump's start temperature when working in “SANI”and use keys 1 or 2 to change the
“SET SANI”temperature (we recommend keeping this temperature at 70–75°C). Pump will only start upon
reaching of said temperature.
We recommend re-setting stove with work power from 1 to 5 when DHW is no longer required.
If the water is particularly hard, it is indispensable to install a lime scale device at the inlet to the heat
exchanger, which must be selected on the basis of the features of the water.

18
DHW POWER WORK PHASE

19
7.4 Work phase with open room thermostat contact
A bridge clamp is found at back of stove for connecting a room thermostat.
OPERATION PRINCIPLE
With open contact:
1. The stove passes directly to the “ECO TOFF” operation economy mode.
2. The stove pump switches off.
3. The temperature in the boiler increases due to thermal inertia until reaching the
temperature set on “SET H2O”, displaying “ECO H2O”.
4. The stove now automatically switches off if at least one of the following
conditions exist:
If it remains in Functioning Economy “ECO-H2O” for a time set on Pr23
(120 minute default setting).
If it exceeds temperature differential set on Pr12 (10°C default setting) or
H2O Temperature > (“SET H2O” + Pr12)
N.B.: the pump is calibrated to start with SET H2O + 5°C temperatures in all
stoves (DHW set-up).
ATTENTION: The above-described functioning on BI-FIRE MID and BI-FIRE stove only works on pellet
side. Room thermostat connection is automatically excluded with wood side on.
The stove will automatically reactivate if both of the following conditions occur:
If the contact of the room thermostat closes.
If it drops below temperature differential set on Pr12 (10°C default setting) or H2O temperature < (“SET
H2O” –Pr12).
If the above-mentioned condition occurs when the stove is still carrying out the switch off cycle, it is required to
wait until it ends.
