Outline of specifications
1)
Setting at the centerl controller side enables to select the
contents which can be operated on the remote controller
at indoor unit side.
1)
Selecting [AUTO] mode enables an energy-saving to be
operated.
2) When using the remote controller RBC-AMSU5 ,
"Energy saving operation" can be performed even in
cooling mode and heating mode.
3)
The setup temperature is shifted (corrected) in the range
not to lose the comfort ability according to input values of
various sensors.
4)
Data (Input value room temp. Ta, Outside temp. To, Air
volume, Indoor heat exchanger sensor temp. Tc) for
20 minutes are taken the average to calculate correction
value of the setup temperature.
5)
The setup temperature is shifted every 20 minutes, and
the shifted range is as follows.
In cooling time: +1.5 to – 1.0K
In heating time: –1.5 to +1.0K
1) This control is operated by selecting [AUTO] operation mode.
2) COOL operation mode:
It is controlled according to the
following figure if To < 28°C.
Remarks
3) HEAT operation mode:
It is controlled according to the
following figure if To > 15°C.

In case of the wireless type, the display lamp does not
change but the contents are same. If operating an item
which is prohibited by the central control mode from the
remote controller, it is notified with the receive sound,
