1 CONTROL PANEL MENU

The following procedure is used to access the four boiler programming menus:

from the main menu C; A e C for approx. 6 seconds; B to see menus 1 - 2 - 3 - 4; B to confirm the selected menu; C to go back one menu at a time to the main menu.

The four menus are:

1 ENDUSER (visible pressing the button C)2 COMMISSIONING (visible with a buttons combination)3 ENGINEER (visible only with PASSWORD 10101)

4 OEM (visible only with PASSWORD)

1.1 ENGINEER menu

Access Engineermenu as described in section 1.This level includes all parameters present on Enduser and Commissioning menus.The details of this menu are given in next section.Some menus are avaible only if the system is correctly configured (e.g. solar menu).The parameters with grey underlight are different default values depending on boilermodel.

4 GAS ADAPTIVE SYSTEM

LUNA4 is provided with a brand new system GAC (Gas Adaptive Control): the electroniccontrol together with the gas valve grant an automatic control of the combustion and ensurethe following advantages during the installation as well as for the end user:

Reduction of the time for the installation, as any manual intervention has been deleted(adjustment or nozzles change); The boiler is able to adapt to the quality of the gas and to the length of the flue tubesmaintaining a constant efficiency helping a reduction of the gas consumption and generatingless pollution.

The Gas Adaptive System maintains correct combustion by comparing the measured FlameSignal and the Reference Flame Signal. The Reference Signal follows a set curve dependingon fan speed and it is part of the software.

The system measures constantly the signal during the operation of the boiler and adjusts thegas flow rate in order to maintain the correct signal and the correct CO level. In this way isalso considered the oxidation of the component (flame electrode and burner).

The electronic gas valve has a modulator used to set the properly flame signal and so thecorrect air / gas ratio (LAMBDA).If the system is not able to assure the correct flame signal the boiler goes in lockout.

The flame signal detected by the burner control is independent from:- value and type of supply voltage;- quality of the ground in the installation.

5 FAULT FINDING1 Initial Fault Finding Checks

1. Check that gas, water and electrical supplies are availableat the boiler.

2. Electrical supply = 230V ~ 50 Hz.

4. The preferred minimum gas pressure is 10 mbar.

5. Carry out electrical system checks, i.e. Earth Continuity,Resistance to Earth, Short Circuit and Polarity with a suitablemeter.

6. Ensure all external controls are calling for heat and checkall external and internal fuses. Before any servicing orreplacement of parts, ensure the gas and electrical suppliesare isolated.

18.2 Error Codes1. If a fault occurs on the boiler an error code may be shownby the facia display.

2. The codes are either a flashing two or three digit, numberpreceded by the symbol 'E'.

E20, E28, E40, E50, E83, E151, E160 and E384 indicate possiblefaulty components.

E110 and E111 shows overheat of the primary.

E117 is displayed when the primary water pressure is morethan 2.7 bar.

E118 is displayed when the primary water pressure is lessthan 0.5 bar.

E133 indicates that the gas supply has been interrupted,ignition has failed or the flame has not been detected.

E125 is displayed in either of two situations:-i) If within 15 seconds of the burner lighting the boilertemperature has not changed by 1.ii) If within 10 minutes of the burner lighting the boilertemperature twice exceeds the selected temperature by 30.In these instances poor primary circulation is indicated.

E128 is displayed if there has been a flame failure during normalburner operation.

3. By pressing the 'Reset' button for between 1-3 seconds whenE 110, E125 & E133 are displayed it is possible to relight theboiler.

4. If this does not have any effect, or error codes are displayedregularly further investigation is required.

.

NOTE: These checks must be repeated after anyservicing or fault finding.

NOTE: When instructed press and hold

the Reset for between 1-3 seconds toreset the boiler.
