Connection of QAA73 To LMU34 via AGU2.002
The LMU34 can be configured for different applications by setting parameters via the
QAA73.
To make this procedure easy for the installer, several sets of parameters have been
defined, every set consisting of several parameters, and one set for each application.
The installer will only select the particular parameter set he needs. He cannot select
single parameters.
Only the manufacturer of the LMU34 can define these parameter fields.
The boiler manufacturer is able to set the parameters via OCI425 / ACS425.
