Programming Board Parameters Using The Avs 77 Climate Controller - Baxi LUNA3 COMFORT HT Gebrauchsanleitung Für Den Benutzer Und Installateur

21. PROGRAMMING BOARD PARAMETERS USING THE AVS 77 CLIMATE CONTROLLER

To set the boiler parameters, proceed as follows:
• press and hold down IP for at least three seconds;
• press and hold down and then press
When the function is enabled, "OF 725" appears on the display
followed by the software version of the LMU34 board.
To modify boiler parameters, proceed as follows:
• Press +/- and
together and hold down for 3 seconds;
(this accesses the list of parameters, the display shows OF
504 alternating with the parameter itself).
• press buttons +/- to scroll the parameters (see table be-
low);
• press buttons +/- to modify individual parameters;
• press OK to confirm the modified parameter and return to the
list of parameters;
• press IP to exit
