7.5.1 Setting the heating capacity with QAA 73
You can set the heating capacity alongside the above-named
settings on QAA 73.

You can end the control stop function by pressing the chimney
sweep button (9) (> 1 sec).
Changing the max. heating capacity
If you press and hold the chimney sweep button (9) (> 9 seconds)
the newly set capacity will count as the maximum heating
capacity; the LMU...parameter NHzMax or PHzmax will adjust
accordingly depending on whether the speed limit for each
parameter specification is active or not.
7.5.2 Programming of LMU via QAA 73
Below is the description of the button operation on QAA 73.
Entry into LMU input...Programming level
On QAA73 press ... «+
 » or «+  » buttons in the info level
simultaneously (approx. > 3 seconds). You are now in the
programming levels of the LMU.
End user level
After input in LMU programming levels, you will land directly in the
end user level.
Specialist level
On QAA 73 press «

/

» buttons simultaneously (approx. > 3
seconds)
OEM level
On QAA 73 press «
 /  » buttons simultaneously (approx. > 9
seconds) and enter code.
Change the parameter
To conform with QAA73 system with subsequent line change
(In this type of programming, the value will be assumed. After the
first parameter change, «183» will appear on the display code
(12).
Complete the programming
Press the information or operation type button. If no change or
setting occurs for 8 minutes, the programming will end
automatically
In the ending of the program described, no parameters
changed afterwards will be assumed!
After completing the programming display code
«183» will disappear from display (12)
The programming described here applies only to the
values of the LMUs connected on QAA 73...
This will not affect QAA 73 parameters.
If QAA 73 is used for programming, then connection and
disconnection may be carried out only in dead-voltage status.
