of the possible function (most functions are on FCQ, less functions are on FBQ)
4 Between brackets are the required Refnet kits mentioned, that are necessary to install the
combination
5 For unit specification of the outdoor units and the indoor units refer to the unit specifications
mentioned for pair systems.
6 Nominal cooling capacities are based on the following conditions: indoor air temperature: 27°CDB,
19°CWB, outdoor temperature 35°CDB. Nominal heating capacities are based on the following
conditions: indoor air temperature: 20°CDB, outdoor temperature 7°CDB, 6°CWB.
