100% calibration, manual

Calibration procedure

.

•Put the boiler (preferably) in heating mode or else in DHW mode. Press the 

Reset

 button (detail 6 - fig. 1) for 10 se-

conds.

•The display shows 100 and the text 

”Co”

 flashing; press the "H" button (ref. 4 fig. 1) to set and view 120.

•Then press the "DHW +" button (ref. 2 fig. 1) to set 123.
•Press the 

Reset

 button (ref. 6 fig. 1) once.

•The display shows 

Ts

 flashing; press the "h" button (ref. 4 fig. 1) once.

•The display shows 

Sc

 flashing; press the 

reset

 button once.

•The display shows 

Sc

 alternating with 01 flashing;

•Press the "h" button (ref. 4 fig. 1) until displaying 

Sc

 alternately with 15 flashing;

•Press the "DHW +" button and the display shows "00";
•Press the "DHW +" button and the display shows "01";
•Press the "h" button (ref. 4 fig. 1) and the 100% calibration mode will activate, displaying the message “CA ”

and “LI” alternating.

•After calibration, the display will show 

Sc

 alternating with 15 flashing.

•Press Reset (ref. 6 fig. 1) for 10 seconds to exit the 

Sc

 menu.

100% calibration, automatic

Automatic calibration can take place in some cases in the absence of a DHW or heating demand or after a reset due to
a fault and is indicated on the display by the flashing flame symbol.

Loading parameters with “BCC KEY”

The 

“BCC KEY”

 device allows the updating of combustion parameters for boiler type.

It is used in case of replacement of the PCB of some boiler models.

To use the 

“BCC KEY”

, refer to the instructions contained in the 

kit code 3980H730

.

TEST mode activation

Perform a heating or DHW demand.

Press the heating buttons (detail 3 and 4 - fig. 1) together for 5 seconds to activate 

TEST mode

. The boiler lights at the

maximum heating power set as described in the following section.

The heating and DHW symbols (fig. 32) flash on the display; the heating power will appear alongside.

fig. 32- TEST mode (heating power = 100%)

Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power (Minimum=0%, Maximum=100%).

By pressing the DHW 

“-” button

 (detail 1 - fig. 1), boiler output is immediately adjusted to minimum (0%).

Wait about 1 minute for stabilisation.

By pressing the DHW 

“+” button

 (detail 2 - fig. 1), boiler output is immediately adjusted to maximum (100%).

If the TEST mode is activated and enough hot water is drawn to activate the DHW mode, the boiler remains in TEST
mode but the 3-way valve goes to DHW.

To deactivate the TEST mode, press the heating buttons simultaneously (details 3 and 4 - fig. 1) for 5 seconds.
