Notes:
▪ The P1P2 connection between the remote controller, the EKEA
master and the EKEA slaves is always required.
▪ All other connections are optional depending on the situation:
▪ In general, all inputs and outputs only need to be connected to
the EKEA master.
▪ If C1C2 is used, it needs to be connected to the EKEA master
and to all EKEA slaves.
▪ If T5T6 is used, it only needs to be connected to the EKEA
master, the connection can be short-circuited on the EKEA
slaves.
▪ If T5T6 is not used, the connection needs to be short-circuited
on the EKEA master and on all EKEA slaves, see
"11.3Operation signals"[413].
▪ If K7K8 is used, it only needs to be connected to the EKEA
master.
▪ There are other electrical connections to the EKEA control box
that are not shown in the figure, these are left out for the clarity of
the figure.
11.9.2 Separate refrigerant circuits system
The figure below shows how the inputs and outputs must be
connected in case of a separate refrigerant circuit system. This
means that the expansion valve kits of the EKEAs configured as
master and slave, are connected to different refrigerant circuits.
