10.1 BASIC CONTROL PANEL SETTINGS

INITIAL IGNITION CONFIGURATION PROCEDURE

When igniting the boiler for the first time, perform the following procedure (the text is written in 

ENGLISH

 until the user is requested 

to set his/her language as illustrated in sequence A-B-C of the figure indicated below):

• 

B

 for 

5 seconds;

• 

the display shows a percentage value from 1 to 100. Data synchronisation takes a few minutes to complete;

• 

set the language, date and time.

11. FILLING THE SYSTEM

The pressure displayed on the pressure gauge has to be between 

1

 - 

1.5

 bar, with the system cold. If it is lower, turn the system 

filling tap installed by the fitter.

IMPORTANT: open the tap very slowly in order to vent the air.

The boiler is fitted with a hydraulic pressure switch which prevents the boiler from working if there is no water.

If pressure drops occur frequently (monthy basis), have the system checked by the Authorised technical service agent.

12. SYSTEM AIR EXTRACTION FUNCTION

This  function  is  used  to  facilitate  the  elimination  of  the  air  inside  the  heating  circuit  when  the  boiler  is  first  installed  or  after 

maintenance when the water is drained from the primary circuit and re-filled.

The electronic board will activate a pump on/off cycle lasting 10 minutes. The function will automatically stop at the end of the 

cycle.

To manually interrupt the function, repeat the procedure described above. When the function is disabled, “ 

off

” is shown on 

the display. 

During this phase it is recommended to keep the pressure in the system at a value between 1 and 1.5 bar.

13. GAS VALVE COMMISSIONING

To commission the gas valve, enable the commission function as described in 

section "SPECIAL FUNCTIONS" and carry out the following operations:

1) Calibrating MAXIMUM heat output.

Check that the

/O

2

  measured  on  the  flue  duct,  with  the  boiler  operating 

at maximum heat capacity, matches that indicated in table 1C. If it does not, 

remove the threaded cap on the gas valve and turn the adjustment screw (

V

). 

Turn  the  screw  clockwise  to  decrease  the  level  of 

  and  anti-clockwise  to 

increase it.

2) Calibrating REDUCED heat output

Check that the 

/O

2

 measured on the flue duct, with the boiler operating at 

minimum heat capacity, matches that indicated in table 1C. If it does not, remove 

the threaded cap on the gas valve and turn the adjustment screw (

K

). Turn the 

screw clockwise to increase the level of 

 and anticlockwise to decrease it.

V

Gas flow adjustment screw

Pi

K

OFFSET adjustment screw

For each CO

2

/O

2

 value found at the maximum thermal capacity, there is a range 

of CO

2

/O

2

 values at the minimum thermal capacity shown in the same line of 

the table.

The nominal calibration values of the gas valve for each type of gas used are shown in bold.

The CO

2

/O

2

 values are with the cover closed.

The maximum permitted CO value must be lower than 250 ppm.
