CONNECTING TO THE HEAT PUMP
ERS S10 contains an accessory board (AA5) that con-
nects directly to the main product’s PCB (terminal block
AA2-X30).
The communication cable (W102) is connected to the
accessory board (AA5) from the factory.
If more accessories are to be connected, or are already
installed, the boards are connected in series.
Because there can be different connections for accessor-
ies with accessory board (AA5), you should always read
the instructions in the manual for the accessory that is
to be installed.
