Central control mode<br />
selection<br />
1) Setting at the centerl controller side enables to select the<br />
contents which can be operated on the remote controller<br />
at indoor unit side.<br />
2) Setup contents<br />
• 64 line central controller (TCB-SC642TLE2)<br />
[Individual]: Operated on the remote controller<br />
(Priority to second pushing)<br />
[Central 1]: ON/OFF operation cannot be operated on<br />
the remote controller.<br />
[Central 2]: ON/OFF, mode selection, temp. setup<br />
operations cannot be operated on the<br />
remote controller.<br />
[Central 3]: Mode selection and temp. setup operations<br />
cannot be operated on the remote controller.<br />
[Central 4]: Mode selection cannot be operated on the<br />
remote controller.<br />
∗ In case of the wireless type, the display lamp does not<br />
change but the contents are same. If operating an item<br />
which is prohibited by the central control mode from the<br />
remote controller, it is notified with the receive sound,<br />

Energy-saving<br />
control<br />
1) Selecting [AUTO] mode enables an energy-saving to be<br />
operated.<br />
2) The setup temperature is shifted (corrected) in the range<br />
not to lose the comfort ability according to input values of<br />
various sensors.<br />
3) Data (Input value room temp. Ta, Outside temp. To, Air<br />
volume, Indoor heat exchanger sensor temp. Tc) for<br />
20 minutes are taken the average to calculate correction<br />
value of the setup temperature.<br />
4) The setup temperature is shifted every 20 minutes, and<br />
the shifted range is as follows.<br />
In cooling time: +1.5 to – 1.0K<br />
In heating time: –1.5 to +1.0K<br />
