16 Configuration

16.1 To configure the control box

Follow the steps below to configure EKEA. For the configuration of other parts of the system (example: outdoor unit, (BS/)SV unit, other indoor

units,… ; see the corresponding manuals). Do NOT start the operation of EKEA before the configuration steps have been completed. If EKEA

is started while the configuration is not completed, the system could be damaged.

EKEAs in group control?

Will master-slave configuration of EKEAs be

used?

▪ Inputs and outputs are connected to the EKEA(s). This includes the T5T6 jumper, if needed. This jumper is only allowed for R410A applications (see "11.3

Operation signals").

▪ A remote controller is connected to the EKEA(s).

▪ Connect the power supply cable to the EKEA(s).

▪ Exceptions:

▪ In case of master-slave configuration, do NOT connect any inputs/outputs to the EKEAs yet.

▪ In case of group control (but not master-slave configuration):

▪ Do NOT connect C1C2 input in case it is used for Z control yet.

▪ Do NOT connect T3T4 and T1T2 wires yet.

▪ Do NOT connect the cables of the expansion valve yet. This should NOT be done before setting the capacity class, because it may damage the expansion

valve body.

▪ Do NOT connect F1F2 transmission cables to the outdoor unit or (BS/)SV units yet. This can only be done after the capacity class is set.

Only in case of master-slave applications this can be set with

group setting (21-11). Otherwise, use 11-11.

In case of EKEAs in group control make sure that all the EKEAs are

set to the same control type.

Group control = Multiple EKEAs are connected to one remote

controller (R/C). 1 remote controller –to– many EKEAs pairing.
