Air to Air Heat Exchanger with DX Coil Unit

Ventilation mode setting

The setting of the ventilation mode can be changed when using the remote controller for air conditioners
(RBC-AMT32E).
* 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 [EA] in step 3 on page 18.
• Select a value from the table on the below in step 4 on page 19.
