6.28 Parameter stick AGU2.56...
6.28.1 Wrong use and risks
The parameter settings of units installed in the field can be changed with the help of the
parameter stick. Using the stick, the heating engineer can create a spare LMS14... and
set basic parameters. This means that he can use an LMS14... with factory-set
parameters and replace these parameters by any parameters defined by the OEM. The
LMS14... is supplied with a number of safety mechanisms and checks that prevent
inadvertent parameter settings. For practical reasons, some of these checks can be
deactivated. This chapter contains notes to be observed when creating data sets,
aimed at preventing any inadvertent parameter settings.
6.28.2 Checks made by the LMS14...
Before a data set is transferred to the LMS14..., the unit checks and evaluates the
following features (among other things):
-
Parameter version
-
Device family
-
Parameter set number
-
OEM parameter set number
-
OEM parameter set group number
-
OEM boiler type
If the data set contains an online DD, the online DD group number is checked also.
When creating a data set, the person producing it can define the criteria to be checked
or not checked.
If checks are canceled here, it might be possible to transfer the data set to a larger
group of devices.
The following checks can be canceled:
-
Parameter set number
-
OEM parameter set number
-
OEM parameter set group number
-
OEM boiler type
Note!
It is not possible to import a data set from one device family into a different one.
Therefore, it may be necessary to create a separate data set for each device family
even if the data sets themselves are not device-specific.
Warning!
Before canceling checks, identify the units to which the data set shall be
transferred and find out what consequences this will have for the respective
unit. In the worst case, the parameter settings of the unit will be wrong!
