CONTROL CONTROL PANEL MENU

The following procedure is used to access the four boiler pro- gramming 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 2 COMMISSIONING 3 ENGINEER 4 OEM

(visible pressing the button C) (visible with a buttons combination) (visible only with PASSWORD 10101) 10101) (visible only with PASSWORD)

ENGINEER ENGINEER menu men u

 Access Engineer  menu  menu 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 boiler model.

GAS ADA PTIVE SYSTEM

LUNA4 is provided with a brand new system GAC (Gas Adaptive Control): the electronic control together with the gas valve grant an automatic control of the combustion and ensure the 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 t he flue tubes maintaining a constant efficiency helping a reduction of the gas consumption and generating less pollution. The Gas Adaptive System maintains correct combustion by comparing the measured Flame Signal and the Reference Flame Signal. The Reference Signal follows a set curve depending on fan speed and it is part of the software. The system measures constantly the signal during the operation of the boiler and adjusts the gas flow rate in order to maintain the correct signal and the correct CO level. In this way is also 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 the correct 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.

FAULT FAUL T FINDING 1 Initial Fault Finding Checks 1. Check that gas, water and electrical supplies are available at the boiler. NOTE: When instructed press and hold the ‘Reset’ for between 1-3 seconds to reset 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 suitable meter. NOTE: These checks must be repeated after any servicing or fault finding. 6. Ensure all external controls are calling for heat and check all external and internal fuses. Before any servicing or replacement of parts, ensure the gas and electrical supplies are isolated.

E20, E28, E40, E50, E83, E151, E160 and E384 indicate possible faulty components. E110

and E111 shows overheat of the primary.

E117 is displayed when the primary water pressure is more than 2.7 bar. E118 is displayed when the primary water pressure is less than 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 boiler temperature has not changed by 1°. ii) If within 10 minutes of the burner lighting the boiler temperature 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 normal burner operation.

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

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

CH system pressure less than 0.5 bar or more than 2.7 bar. NO

J

Ensure that the system and boiler are fully vented.

YES

Restore System Pressure YES

Check wiring and pcb connection at connector x22 is there approx. 5 V DC between the green and black terminals

Replace pressure sensor  NO

Replace PCB

NO

System fault, correct.
