FUNCTIONS CODES
CODE TYPE OF FUNCTION DESCRIPTION
CHIMNEY-SWEEPER
FUNCTION ON
THE CHIMNEY-SWEEPER FUNCTION IS ACTIVATED BY KEEPING PRESSED
"SERVICE" PAD FOR 5 SECONDS. TO CANCEL IT RESET THE UNIT BY
PUSHING ON/OFF BUTTON.
THIS FUNCTION BRINGS THE UNIT TO THE MAX HEATING GAS PRESSURE
FOR 15 MINUTES WITHOUT MODULATING DOWN. IT IS USEFUL WHILE
CARRYING ON THE COMBUSTION TEST.
ANTI-FROST FUNCTION
HEATING CIRCUIT
THIS FUNCTION COMES INTO OPERATION WHEN THE HEATING SENSOR
SENSES A 5°C TEMPERATURE. THE BOILER STARTS AT THE MINIMUM GAS
PRESSURE, WITH THE 3-WAY VALVE IN WINTER POSITION. THE BOILER
STOPS WHEN THE TEMPERATURE TAKEN BY THE SENSOR HAS REACHED
30°C .
ANTI-FROST FUNCTION
DOMESTIC HOT WATER
CIRCUIT
THIS FUNCTION COMES INTO OPERATION WHEN THE HOT WATER SENSOR
SENSES A 4 °C TEMPERATURE. THE BOILER STARTS AT THE MINIMUM GAS
PRESSURE, WITH THE 3-WAY VALVE IN SUMMER POSITION AND HEATS THE
HOT WATER CIRCUIT. THE BOILER STOPS WHEN THE TEMPERATURE TAKEN
BY THE HOT WATER SENSOR HAS REACHED 8°C .
ANTI-FROST FUNCTION
D.H.W. CIRCUIT - STORAGE
BOILERS.
SAME OPERATION AS THE ANTI-FROST FUNCTION OF D.H.W. CIRCUIT FOR
INSTANTANEOUS BOILERS.
LEGIONELLA PREVENTION
FUNCTION.
FUNCTION ACTIVE FOR STORAGE BOILERS ONLY. IT COMES INTO
OPERATION EVERY 7 DAYS .
IT BRINGS THE HOT WATER TEMPERATURE OF THE STORAGE CYLINDER UP
TO 60°C WHATEVER TEMPERATURE VALUE IS SET FOR HOT WATER.
NOT COMPATIBLE
REMOTE CONTROL.
THIS CODE IS DISPLAYED WHEN THE REMOTE CONTROL OR OUTSIDE
TEMPERATURE SENSOR CONNECTED ARE NOT ORIGINAL RADIANT PARTS.

MANOMETRO
9: Mechanical minimum gas pressure setting
The mechanical minimum gas pressure is factory calibrated on all boilers at 17/18 mmH20.
When replacing the gas valve adjust the mechanical minimum pressure as follows: :
•Using a single cut screwdriver turn Dscrew (fig.1 ) clockwise and tight it ;
•To adjust the mechanical minimum, turn Dscrew (fig.1) counter-clockwise for
two complete turns.
Parameter 10 setting: MINIMUM HEATING OUTPUT SETTING
To check or modify the existing pressure value:
a. insert a manometer into the gas valve pressure point B(fig.1);
b. Put ON / OFF button 1in OFF position ( );
c. Push pad 6and simultaneously and keep them pressed;
d. Put ON / OFF button 1in ON position ( ) and wait until the display shows - ;
e. Release pad 6and ;
f. Keeping pad pressed, press pad 6and select parameter no. ;
g. Release service pad , press and release service pad ;
h. The display will show the parameter value to be set or modified;
i. The manometer inserted in the pressure point B(fig. 1) will show the minimum gas pressure;
j. If that value is different than the one stated on the data plate, modify it by pressing pad 6to increase or pad to decrease gas pressure ;
k. Once the minimum gas pressure has been adjusted, switch the boiler OFF by putting ON / OFF button 1in OFF position ( );
l. Remove the silicon pipe from the pressure point B(fig.1), close tightly the pressure point screw and make sure there are no gas leaks;
m. Position the ON / OFF button 1in ON position ( );

l. Open the hot water tap at the maximum flow and temperature to switch the boiler ON;
m. The manometer inserted in the pressure point B (fig. 1) will show the maximum gas pressure
n. If that value is different than the one stated in the data plate (see Gas Pressure adjustment table) modify it as follows:
o. Remove the aluminium cap A(fig.1) and, with a screwdriver, turn the plastic screw;
p. Turn clockwise to increase gas pressure and counter clockwise to decrease gas pressure;
q. Once the maximum gas pressure has been adjusted screw aluminium cap A back to position onto the gas valve;
r. Switch the boiler OFF by putting ON/OFF button 1in OFF position ( );
s. Remove the silicon pipe from the pressure point B(fig.1), close tightly the pressure point screw and make sure there are no gas leaks.

WIRING DIAGRAM FOR REMOTE CONTROL INSTALLATION (no zone valves)
Fit the interface (fig. 2) on the circuit board (fig. 1) into the holes A and B provided (see fig. 1).
Connect plug M1 on the interface circuit board (fig. 2) to plug M11 on the modulation circuit board (fig. 1).
Connect the grey and orange wires in plug M2 of the interface circuit board (fig. 2) and in the terminal block (fig.
4).
Connect the wires of plug M3 on the interface circuit board (fig. 2) in the terminal (fig. 4).
Remove the link TA-TA (fig. 3) and set the boiler to SUMMER mode.
Connect the remote control to the terminal block (fig. 4) using a cable with a minimum section of 2 x 0.5 mm2
section and max. length of 50 m being careful to observe the +/- polarity.
THE EXTERNAL SENSOR IS OPTIONAL. The connection can be made to either the remote control (fig. 5) or to
the terminal block (fig. 3 - dotted line) on the terminals marked SE-SE.
WARNING! The remote control connection cable must pass through a channel which is separate from any system
supplied with power. If this is not possible, fit a screened cable.
