 Ventilation Fan speed setting
The setting of the ventilation Fan speed can be changed when using the remote controller for air conditioners
(RBC-AMT32E, RBC-AMS41E) or using the system without the remote controller.
* Adjusting this setting is necessary for the header unit when using a system equipped with the Air to Air Heat
Exchanger with DX Coil Unit only (RBC-AMT32E can not be used.), and for the Air to Air Heat Exchanger with
DX Coil Unit with the smallest address number when using a system equipped with the Air to Air Heat Exchanger
with DX Coil Unit and air conditioners.
* When the remote controller NRC-01HE is installed, this setting is invalid. (The remote controller can be used for
operation.)
• Select [EB] in step 3 on page 70.
• Select a value from the table on the below in step 4 on page 70.

* When [0004] is selected, adjust setting of the unbalanced ventilation Fan speed (Code: 48).
 Setting for changing the operation output
Terminals 1 and 2 on the terminal block 3 for external devices can be used to connect an auxiliary fan or to use the
operation output for operating external devices connected to the terminal. It can be specified when the operation
output is used.
* Apply this setting for the Air to Air Heat Exchanger with DX Coil Unit to which an external device is connected.

 Abnormal signal / bypass mode signal output setting
Terminals 3 to 5 for external output can be used to detect an abnormal signal / bypass mode signal output. Output
signal to be detected can be selected.
* Adjust this setting for the Air to Air Heat Exchanger with DX Coil Unit to which an external output is connected.
* When [0000] is selected, signal transfer is on if one of the units in the group has trouble.
