Installation Manual
Operation
• The central controller can be used to ON/OFF the whole
system and separately ON/OFF groups of the Air to Air
Heat Exchangers.
• The central controller cannot be used to control the
ventilation fan speed or ventilation mode of the Air to Air
Heat Exchanger.
• If the central controller and the remote controller for the Air
to Air Heat Exchanger are used, the latter operation
overrides the former.
Air to Air
• The remote controller for the Air to Air Heat Exchanger
Heat
(NRC-01HE) can be used to control the ventilation fan
Exchanger
speed and ventilation mode of the Air to Air Heat
Exchanger.
A B
* The remote controllers for the air conditioners (RBC-
A B
AMT32E) cannot be used to control the group of the Air
to Air Heat Exchangers. Only on/off operation is
available for RBC-AMS41E.
• The central controller can be used to ON/OFF the whole
system and separately ON/OFF groups of air conditioners
and the Air to Air Heat Exchangers. (Air conditioners and
Air to Air Heat Exchangers are not linked in this system.)
• The central controller cannot be used to control the
ventilation fan speed or ventilation mode of the Air to Air
Heat Exchanger.
• The operation of the central controller overrides that of the
remote controllers for the Air to Air Heat Exchangers and
the air conditioners. However, the operation of the remote
controller for the Air to Air Heat Exchanger does not affect
that of the remote controller for the air conditioner and vice
Air to Air
Heat
versa.
Exchanger
• The remote controller for the Air to Air Heat Exchanger
(NRC-01HE) can be used to control the group of the air
A B
conditioners instead of using the remote controller for the
air conditioner.
A B
• The remote controller for the Air to Air Heat Exchanger
(NRC-01HE) can be used to control the ventilation fan
speed and ventilation mode of the group of the Air to Air
Heat Exchangers.
* The remote controllers for the air conditioners (RBC-
AMT32E) cannot be used to control the group of the Air
to Air Heat Exchangers. Only on/off operation is
available for RBC-AMS41E.
• The central controller can be used to ON/OFF the whole
system. It can also be used to ON/OFF the Air to Air Heat
Exchanger separately (*).
• The central controller cannot be used to control the
ventilation fan speed or ventilation mode of the Air to Air
Heat Exchanger.
• If three control devices are used; the central controller and
the remote controllers for the Air to Air Heat Exchanger and
the air conditioner, the latter operation overrides the former
regardless of which device is used.
• The remote controller for the Air to Air Heat Exchanger
Air to Air
NRC-01HE can be used to control the ventilation fan speed
Heat
Exchanger
and ventilation mode of the Air to Air Heat Exchanger.
• If the remote controller for the air conditioner (RBC-
A B
AMT32E and RBC-AMS41E) is used; the ventilation fan
speed or ventilation mode of the Air to Air Heat Exchanger
can not be controlled.
A B
• The remote controller for the air conditioner or the Air to Air
Heat Exchanger can be used to ON/OFF the Air to Air Heat
Exchanger separately.
* Setting modifications are required for separate control.
