Air to Air Heat Exchanger
Installation Manual
1) When switching the remote controller between invalid/valid from an external device
SW1 [Remote controller Invalid: ON, Valid: OFF]
• For NRC-01HE (remote controller for the Air to Air Heat Exchanger), when one of the buttons below is
pressed,
blinks and the operation is invalid.
* [ON/OFF] button
* [VENT] button
* [VENT MODE] button
* [VENT FAN] button
• For RBC-AMT32E, AMS41E (remote controller for the air conditioner), pressing the [ON/OFF] button has
no effect.
• When the remote controller is inoperable, the 24-hour ventilation mode and nighttime heat purge operation
are not available.
• If a command is sent to one of the units in the group, the invalid/valid setting of the remote controller in the
group can be switched.
2) When switching between low/high from an external device
SW2 [Low: ON, High: OFF]
• For NRC-01HE (remote controller for the Air to Air Heat Exchanger), the message on the display is
changed. However, when the air conditioner operates Air to Air Heat Exchanger system linked with air
conditioners, ventilation fan speed (Low/High) is changed though the ventilation amount is not shown on
the display.
• If a command is sent to one of the units in the group, all the Air to Air Heat Exchangers in the group operate
together.
• The latter operation of the remote controller or the external device overrides the former.

3) When switching between Bypass mode/Heat exchange ventilation from an external device
SW3 [Bypass mode ventilation: ON, Heat exchanging ventilation: OFF]
• For NRC-01HE (remote controller for the Air to Air Heat Exchanger), the message on the display is
changed.
• If a command is sent to one of the units in the group, all the Air to Air Heat Exchangers in the group operate
together.
• The latter operation of the remote controller or the external device overrides the former.
NOTE
The operation mode will be automatically changed to Heat exchange mode when outdoor air temperature is below 15°C
during Bypass mode. The display remains Bypass mode.

Contact is on during normal operation as factory default.
• Contact is off during 24-hour ventilation mode, nighttime heat purge operation, delay mode or cold mode
(temperature is below -10°C) as factory default.
• The operation output settings can be changed. Refer to "Setting for changing the operation output" on
page 21.
