Resetting The Boiler
ii
There are two types of errors that can be found on the controller:
Fault and Block.
Fault:
If a fault occurs, the display shows symbols flashing with the writing <ERROR>.
The fault is identified by the error code followed by the letter “E” and is not resettable
unless the problem is corrected.
Block:
If a block occurs, the display shows the symbols flashing together with the <ERROR> and
<>>>OK> symbols alternating.
The block fault is identified by an error code (see the table below) followed by the letter “E”.
Press the OK button on the controller to reset the boiler. The display shows the
<RESET> writing followed by the >>>OK writing.

CONTROLLER
FUNCTIONS
Types of Functions
• Normal functioning (RUN)
This level is what appears on the controller during normal operation.
• User programming (PROGR)
This level allows the user to set the clock, the date, temperature setpoints and time
programs.
• Advanced information (INFO)
This level allows the installer to set a group of advanced parameters and obtain a
sequence of advanced information on the system functioning.
The programming functions operate as follows:
1. To change from RUN to PROGR shortly press the IP button (on the display you should see the running inscription
<PROGR>) for two seconds then the time will appear.
2. To change from RUN to INFO press the IP button for 3 seconds (you should see the running inscription <INFO>)
appear.
3. To return from PROGR or INFO to RUN shortly press the IP button (you will see the running inscription < RUN>) for
two seconds and the screen will go back to normal.

INFO MODE AND ADVANCED SETTINGS
• “HW O>” DHW inlet or storage tank temperature.
• “HW S^” Set-point water sanitary inlet. Value set up with buttons +/-
• “HW MX” Maximum setpoint sanitary circuit (max. setting value)
• “HW Mn” Minimum setpoint sanitary circuit (min. setting value)
DHW CIRCUIT
• “CH Sl” Maximum setpoint heating circuit, setting value with buttons +/- .
Notice: by pushing the comfort button it is possible to change the temp. value from °C to °F.
• “EXT°c” External temperature (with external connecting probe).
• “CH O>” Temperature water heating inlet pipe.
• “CH S^” Set-point water heating circuit.
• “CH MX” Maximum setpoint heating circuit (max. setting value).
• “CH MN” Minimum setpoint heating circuit (min. setting value).
HEATING CIRCUIT
To enter the Information and Advanced Setting modes it is necessary to press the IP button for at
least 3 seconds; the running words “INFO” should appear.
Once the running words appear, press the OK button to scroll through the parameters; when the
big numbers are blinking it is possible to modify the value using buttons +/- .
v

ADVANCED INFORMATION
• “PWR %” Power level/flame modulation (in %).
• “P BAR” Water pressure heating circuit (in bar).
• “F l/M” Water flow outlet sanitary circuit (in liters/min).
Advanced Functions
To setting the boiler’s parameters:
1. Press the IP button for at least 3 seconds
2. Hold the button and press the button
When the function is active on the display the F01 will appear and the value of the selected parameter.
3. Use +/- for scrolling through the parameters;
4. Use +/- for changing parameter values;
5. The new value is automatically saved after 3 seconds;
6. Press the IP button to exit.

Anomalies
The electronic PCB for the LUNA 3 Comfort is able to memorize the last 10 anomalies which have occurred.
Every anomaly has a counter which increases only if the same anomaly is consecutive; the same mistake non-consecutively is recognized as
new.
To see all the information of every single anomaly you have, go to the Advanced Functions and run down the list of parameters to F32.
Parameters F32 to F38 refer to volatile anomalies which means mistakes with no necessity to Reset (for example DHW probe mistake);
parameters from F39 to F41 refer to anomalies that need to be Reset (e.g. safety thermostat).

By using the OK button at each of these parameters you can read:
1. ANOMALY CONSECUTIVE NUMBER (F32 is the last one that occurred so it has a 00 value)
2. ANOMALY CODE (xxE – for example 06E, DHW NTC failure)
3. CONSECUTIVE EVENTS FOR THE SAME ANOMALY
4. TIME (days) PASSED FROM THE SIGNALLING (00 means “today”)
5. SYSTEM STATUS
6. SYSTEM PHASE
7. CENTRAL HEATING DELIVERY TEMPERATURE WHEN THE ANOMALY OCCURRED
By using this information you can keep a SERVICE CHART for the boiler.
