List Of The Modt Commonly Used Parameters; Initial Lighting - Baxi LUNA HT 1.450 Installation And Servicing Instructions

WARNING
Do not confuse these requests for heat with the "flue sweep" or "calibration" functions during which LEDs 2 and
3 both flash quickly on and off in alternation.
12.6 LIST OF THE MOST COMMONLY USED PARAMETERS
QAA73:
parameters which can be set by installation engineer (service)
By pressing the two PROG buttons together for at least three seconds it is possible to access the list of parameters that
the installer can display and/or set.
Press either of these buttons to change the parameter to display or change.
Press the [+] or [-] key to change the value displayed.
Press either of the PROG buttons again to save the change.
Press the information button (i) to quit programming.
Line no. Parameter
HC1 gradient

Selection of central heating circuit temperature curve "kt"
HC1 max. output
72
Central heating system maximum output temperature
74
Type of building
Room compensation
75
Activation/deactivation of the influence of the room temperature. If it is deactivated, the
outdoor temperature sensor must be installed.

Opt Start Max
78
Maximum time the boiler is switched on ahead of the timed program to optimise the
temperature in the premises.
Opt Stop Max
79
Maximum time the boiler is switched off ahead of the timed program to optimise the
temperature in the premises.

PROG HC-1h = as HC1 central heating program less one hour
PROG HC = as central heating program
PROG ACS = specific domestic hot water program (see also program lines 30-36)
FAULT MESSAGES
In the event of fault, the display panel on the QAA73 shows the flashing symbol . Follow the procedure indicated in
paraghraph 14.2.
Note:
Remove the protective plastic coating from the boilers painted panels before lighting.
1. Ensure that the gas and electrical supplies to the boiler are off and that the cold water supply inlet valve and the central heating
flow and return valves are open.
2. Turn on the gas and electrical supplies to the boiler.
3. Ensure all external controls are calling for heat.
4. Set the hot water and central heating temperature selectors to maximum.
5. Set the selector switch to
solenoid will open allowing the main burner to light from the ignition electrodes.
6. The safety shutoff valve device must be tested. To test this device, close the gas cock and verify that the main PCB tries to
relight the gas boiler three times. After the third attempt to relight the boiler, the display carries out the error code E133. To
reset the boiler, turn selector 1 (figure 30) to "R" for at least 1 second (see section 3.3 of the user manual).
