For the combined refrigerant circuit, there can be one or more
outdoor units that are connected to the same refrigerant circuit.
For the separate refrigerant circuits, there is always more than one
outdoor unit, so the number of outdoor units for this system is two or
more.
Additionally, there may be other electrical connections in reality that
are not shown in these examples. These are left out to make the
figure more clear. See other parts of the manual to find out which
electrical connections are required, and see the manual of the
outdoor unit for more information about the system.
Note:
▪ The remote controller is used to share signals between the master
and the slave EKEAs. To ensure proper functioning, the master
EKEA must have the lowest unit number of the remote controller
group. See the user reference guide of the remote controller for
instructions on how to change the unit number.
▪ When you want to use T3T4 on the EKEA master, this EKEA
master must be set as the cooling/heating master first. See:
▪ User reference guide of the remote controller
▪ "16.1To configure the control box"[427]
11.9.1 Combined refrigerant circuit system
The figure below shows how the inputs and outputs must be
connected in case of a combined refrigerant circuit system. This
means that the expansion valve kits of the EKEAs configured as
master and slave, are connected to the same refrigerant circuit.
