The editable parameters are those between 504 and 652 (parameters 650 and 652 are reading only
parameters).
Proceed as follows to access this parameters:
1) Simultaneously press keys 1-4on QAA73 temperature regulator for about 3 seconds. The
“Initialising BMU parameters” appears on the display (line 725).
2) Simultaneously press keys 1-2on QAA73 temperature regulator for about 3 seconds. The
“Initialising BMU SERVICE” (line 504 “TkSmax”).
3) Press keys 1-2to scroll through the list of parameters.
4) To change the value of the selected parameter, press key 3-4 to decrease or increase the value
respectively.
5) Press key 5 to enter the new values and exit programming of the boiler’s electronic main board.
