4.23 Keyboard lockout function
Pressing buttons 1+3 for at least 2sec activates the key lockout; pressing buttons 1+3 again for
at least 2sec re-activates the key.
The display will show LOCK.

Key 2 can stay active if there is a fault to allow the alarm to be reset.
4.24 Interface Stand by
Usually, when there are no faults or heat requests, the display always shows the temperature
measured by the flow sensor.
If within 10 seconds there is no heat request without any key being pressed the interface goes
into stand by.
The display shows the current time, the two points separating the time from the minutes blink
with a frequency of 0.5sec ON and 0.5sec OFF, while the status icons will be active if necessary:
4.25 Replacing interface
The system configuration operations need to be carried out by professionally qualified personnel
of the Technical Assistance Centre.
When replacing the interface board, it might happen that when power up the user is requested
to reset the time and the day of the week (see paragraph "4.5 First commissioning" ). Remember
that no programming of the configuration parameters is needed, the values are recovered from
the control and adjustment board in the boiler. You may need to reset the DHW and heating
setpoints.

4.26 Replacing the board
When replacing the adjustment and control board it might be necessary to re-programme the
configuration parameters. In this case see the P1 to find the board default values, i the factory
settings and personalised settings.
The parameters to be checked and reset if necessary in the event of a board replacement are:
P2.01
P2.02
P3.01
P3.02
P3.03
P3.06
P3.07
P3.09
P3.10
4.27 Combustion Control Parameters
Even if the parameters regarding the new ACC active combustion control system are pre-set
in the factory, it might be necessary to re-programme them if the electronic board is replaced.
ƒ Access the technical parameters as explained in the paragraph "3.23 Access to the parame-
ters" . entering the INSTALLER password.
ƒ Select P2 with the keys and
ƒ Select P2.01.
ƒ Set this parameter based on the type of gas the boiler is using. The values for this parameter
are METHANE = 0 - LPG = 1
ƒ Set the SERVICE password.
ƒ Select the P2 menu and the parameter P2.02
ƒ Set this parameter based on the type of boiler as shown in the table
25 KIS
30 KIS
35 KIS
40 KIS
ƒ Select P2.03.
Value 1 = ZERO RESET : select this option when replacing the detection electrode on the burner
Value 2 = RESTORE select this option when replacing the AKM electronic board

If after maintenance work on the elements of the combustion unit (Repositioning the
detection electrode or else replacing/cleaning the primary heat exchanger, condensate
siphon, fan, burner, flue gases conveyor, gas valve, gas valve diaphragm), the boiler
generates one or more alarms regarding combustion faults, we recommend setting the
main system switch to off for at least 5 minutes.

MAINTENANCE AND CLEANING

Periodic maintenance is an "obligation" required by the law and is essential to the safety, effi-
ciency and duration of the boiler. It allows for the reduction of consumption, polluting emissions
and keeping the product reliable over time.
Before starting maintenance operations:
- close the fuel and water taps of the heating and domestic hot water system.
To ensure product characteristics and efficiency remain intact and to comply with prescriptions of
current regulations, it is necessary to render the appliance to systematic checks at regular inter-
vals. When carrying out maintenance work, observe the instructions given in the "1 WARNINGS
AND SAFETY" chapter.
This normally means the following tasks:
- removing any oxidation from the burner
- removing any scale from the heat exchangers
- checking electrodes
- checking and cleaning the drainage pipes
- checking the external appearance of the boiler
- checking the ignition, switch-off and operation of the appliance, in both domestic water mode
and heating mode
- checking the seal on the couplings, gas and water and condensate connecting pipes
- checking the gas consumption at maximum and minimum output
- checking the position of the ignition electrode
- checking the position of the detector electrode/ionisation probe (see specific paragraph)
- checking the gas failure safety device.
b
After carrying out the maintenance operations the analysis of the combustion products
needs to be carried out to make sure it is operating correctly.
