4.24 Replacing the REC10CH Master
b
The system configuration operations need to be carried out by professionally
qualified personnel of the Technical Assistance Centre.
When replacing the REC10CH MASTER, at the subsequent restart it displays an initial
screen with the firmware revision. Pressing "OK" starts a guided procedure for configuring
the system, see the section "Configuring the system".
Follow the procedure and carry out the MAIN PCB type of configuration.

4.25 Replacing the MAIN PCB board
The system configuration operations need to be carried out by professionally qualified
personnel of the Technical Assistance Centre. The systems continually carries out a
consistency control between the configuration data saved on the MAIN PCB electronic board
and that saved in the REC; therefore, when replacing the MAIN PCB electronic board, it might
happen that the system detects an inconsistency between the data saved on the MAIN PCB
and that in the REC. In this case, the latter will ask the user which of the two configurations is to
be considered valid; selecting to recuperate the configuration from the REC itself it is possible
to avoid reconfiguring the machine:
- select REC10CH.
4.26 Combustion Control Parameters
Even if the parameters regarding the new ACC combustion control system (active
combustion control) are preset in the factory, it might be necessary to programme them, this
is in the case where both electronic boards (MAIN PCB and REC10CH MASTER) need to
be replaced at the same time.

If after maintenance work on the elements of the combustion unit (Repositioning
the detector 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 in these
cases we recommend setting the main system switch to off for at least 5 minutes.
COMBUSTION SELF-CALIBRATION
Function used by the after sales service to make an automatic combustion bend correction if
the CO values (shown in the technical data) are outside the permitted range.

- Set the values to:
RESTORE = use the old bend (if the CO
RESET = use the new bend (if the CO
This parameter is only available when the system is OFF.

Maintenance and cleaning

Periodic maintenance is an "obligation" required by the law and is essential to the safety,
efficiency 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 intervals. When carrying out maintenance work, observe the instructions
given in the "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
During boiler maintenance the use of protective clothing is recommended, in order
to avoid personal injury.
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.
b
If, after replacing the electronic board or having carried out maintenance on the
detector electrode or the burner, the analysis of the combustion products returns
values outside tolerances, it might necessary to change these values as described
in the section "4.26 Combustion Control Parameters".
Note: When replacing the electrode there could be slight variations of the
combustion parameters that fall within nominal values after a few hours of
operation.
b
Do not clean the appliance or its parts with inflammable substances (e.g. petrol,
alcohol, etc.).
b
Do not clean panels, painted parts and plastic parts with paint thinner.
b
Panel cleaning must be carried out only with soapy water.
