OPERATION
RANGE
40°C ÷ 82°C
By pushing the buttons “+” o “-“,you can see on
the display (for 4 seconds) the set temperature.
Through the parameters 425 (min) and 426 (max) is possible to set the maximum and the minimum heating
temperature.
HEATING
REQUEST
Three-way valve ON
Pump ON
The heating request can be performed by: room
thermostat 1, room thermostat 2, programming
clock, REMOCON and room sensor. Icon
and set temperature will be displayed.
When the boiler is at rest the valve is on the
“sanitary” position. When heating is turned on
the motor is supplied (inside shaft in), that
closed the outlet of the secondary exchanger
and puts pump intake in communication with the
heating circuit
The circulating device start is delayed 7 seconds
after heating request in order to allow switching
the 3 way valve; when it starts, the circulating
device intakes the water coming from the
heating system backflow and sends it to the
primary exchanger

To 80% of the set power for Soft Ignition,
adjustable with parameter 220
Flame ionization if checked. (by the detection

Display 5 P1 will indicate if there is no ignition
and there will be a second attempt with 90% of

of the set power for the Soft Ignition. If the third
attempt is unsuccessful block shutdown will
occur 5 01 .

Air pressure switch enabling allows to pass to
the following phase (after the enabling the air

following restart anymore).
If this doesn’t occur, after 20 seconds, the boiler
will stop for safety 6 P1 the Fan remains on
waiting for consent (sealed chamber models).
On the open chamber models instead a
thermostat control is performed (which continues
even while it is operating). If the Flue Control

the temperature rise 102°C a lock out occurs,

Overheat control
NORMAL BOILER OPERATION
After flame detection the boiler is free to
modulate the power according to the required
thermal load. Modulation is carried out
between the maximum heating power values
(adjustable from the control panel with
parameter 231) and the minimum power
value (set made on the gas valve). The shut
down temperature of the burner is operated
as follows:
1° min after flame detection:
T off = T set-point + 8°C
2° min after flame detection:
T off = T set-point + 6°C
starting from the 3rd min after flame
detection:
T off = T set-point + 4°C
This logic is used to prevent the burner from
shutting down too quickly with the system at
temperature.
Next ignition can be delayed from 0 to 7
minutes (default value = 2 min., adjustable
from the control panel with parameter 236)
FLAME
MODULATION
N.B. Starting from heating request, the “limit temperature” (88°C, not adjustable fixed
value) remains on executed by the primary exchanger outlet probe (NTC 1).
If there is a bad circulation through the heating system, the automatic by-pass can be
opened (max capacity 350 l/h).

This function is used to perform proper boiler combustion analysis and maximum and minimum gas
calibration.
Follow the instructions below to enable it:
PRESS
DISPLAY
The display will show this indication
Press Reset button for 5 continuous seconds
With the boiler on “Winter” mode, the 3-way valves is positioned on “heating” and the burner turns on
even without heating requested.
With the boiler on “summer” mode:
owithout sanitary demand the burner turns on in heating;
owith sanitary demand the burner turns on in sanitary.
The delivery temperature (NTC1) is checked during the “Flue cleaner” function, as follows:
“summer” mode → Off: 86°C; On: 81°C;
“winter” mode → Off: 89°C; On: 84°C.
Three different powers can be selected when the function is enabled, after the activation of the function the
boiler goes at the maximum heating power, after that is possible change it:
