ADJUSTING THE MINIMUM OUTPUT (P. LL)
- Select parameter LL (with the boiler OFF) and wait until the boiler
ignites.
- Check the minimum CO
2
value shown on the flue gas analyser
(see "combustion check") corresponds to the values shown in
table 4.
If the CO
2
is different from the values shown in the table, turn the
minimum output adjustment screw (clockwise to increase the value)
with a screwdriver until the value shown in table 4 is indicated.

POSSIBILITY OF ADJUSTING THE HEATING MAXIMUM (P. 23) -
RANGE RATED
- Select parameter 23.
- Press the ENTER key to be able to modify the parameter value.
- Turn the encoder to modify the maximum fan speed (table 5).
- Confirm the new value by pressing ENTER.
The newly set value must be indicated on the adhesive label (sup-
plied) and will become the reference for subsequent checks and ad-
justments, including combustion checks.

POSSIBILITY OF ADJUSTING THE HEATING MINIMUM (P. 24)
- Select parameter 24.
- Press the ENTER key to be able to modify the parameter value
- Turn the encoder to modify the minimum fan speed.
- Confirm the new value by pressing ENTER.
Exit the CALIBRATION & SERVICE functions by pressing the ES
-
CAPE key.
The boiler switches off and ENERGY FOR LIFE is displayed.
Disconnect the pressure gauge and re-tighten the pressure test point
screw.
To restore operation, press the
key.
After each intervention on the adjustment element of the gas
valve, seal it with sealing varnish.
A power failure during the adjustment phase causes the non-in-
troduction of the modified parameters in the memory, which is
indicated by fault 54 on start-up.
Reprogram all the parameters you want to change.
The boiler is supplied with the adjustments shown in the table. De-
pending on plant engineering requirements or regional flue gas emis-
sion limits it is, however, possible to modify this value, referring to the
graphs below.
