Important

The parameters can only be set on models L1+L2 or L1 only; no settings are required on the dedicated board
for L2.
If line 2 is confi gured to use a custom refrigerant, the parameters are automatically confi gured via the pLAN
connection to the L1 controller.
Practical example
Insertion of custom refrigerant (R449a) for single line application.
On KSA or following a request to BU-RET, a document is issued containing all the parameters validated by CAREL
to confi gure and use the required refrigerant.
