Setting the "programming access" password
- The programming of the parameters is accessed by pressing the
key and then pressing the
key for 3 seconds.
- PROG appears on the display followed by CODE.
- Press the ENTER key to confirm.
- Enter the adjustment code by rotating the encoder until the neces-
sary value is reached.
- Confirm the adjustment code by pressing the ENTER key.
- The programming access password is located inside the command
panel.
Setting the "Combustion analysis" password
The programming of the parameters is accessed by pressing the
key and then pressing the
key for 3 seconds.
PROG appears on the display followed by CODE.
Press the ENTER key to confirm.
Enter the adjustment code by rotating the encoder until the neces-
sary value is reached.
Confirm the adjustment code by pressing the ENTER key.
The programming access password is located inside the command
panel.
Calibration stages
The CALIBRATION & SERVICE phases scroll in sequence by turn
-
ing the encoder:
01 type of gas (do not modify this parameter)
02 boiler output (insignificant parameter)
03 degree of insulation of the building (only displayed if an external
probe is connected)
10 DHW mode (do not modify this parameter)
45 thermoregulation curve inclination (only displayed if an external
probe is connected)
47 2CH thermoregulation curve inclination (only displayed if an
external probe is connected)
HP maximum fan speed (do not modify this parameter)
LP minimum fan speed (do not modify this parameter)
SP ignition speed (do not modify this parameter)
HH boiler at maximum output
LL boiler at minimum output
23 maximum heating electrical value adjustment
24 minimum heating electrical value adjustment (do not modify this
parameter)
Parameters 2 - 10 - HP - LP - SP - 23 - 24 must only be modi-
fied by professionally qualified personnel, and only if absolutely
necessary.
The manufacturer declines all responsibility if the parameters
are incorrectly set.

MAXIMUM FAN SPEED (P. HP)
- Select parameter HP.
- press the ENTER key to be able to modify the parameter value.
The maximum fan speed is linked to the type of gas and the boiler
output - table 1.
- Turn the encoder until the desired value is reached
- Confirm the new value by pressing ENTER.
Modify this parameter only when absolutely necessary.
The value is expressed on the display in rpm/100 (e.g. 3.600 = 36).

MINIMUM FAN SPEED (P. LP)
- Select parameter LP.
- press the ENTER key to be able to modify the parameter value.
The minimum fan speed is linked to the type of gas and the boiler
output - table 2.
- confirm the new value by pressing ENTER.
Modify this parameter only when absolutely necessary.
The value is expressed on the display in rpm/100 (e.g. 3.600 = 36).
The value set during this operation will automatically modify the
maximum value of parameter 24.

FAN SWITCH-ON SPEED (P. SP)
- Select parameter SP.
- Press the ENTER key, then modify the value of the parameter. The
standard slow switch-on value is 3300 r.p.m. for model 2.5 IS E
and 3.5 IS E and 3.700 r.p.m. for model 3.0 IS E.
- Confirm the new value by pressing ENTER.
ADJUSTING THE MAXIMUM OUTPUT (P. HH)
- Switch off the boiler.
- Select parameter HH and wait until the boiler ignites.
- Check the maximum CO

value shown on the flue gas analyser
(see paragraph "combustion check") corresponds to the values
shown in table 3.
If the CO

complies with the values in the table, move on to the next
parameter (LL - adjustment of the minimum). If it is different, modify
the value by using a screwdriver to turn the maximum output adjust-
ment screw (clockwise to reduce the value) until the value shown in
table 3 is indicated.
