3.3.1 Appearance and Functions
Remote Controllers
Note: For connection unit series
∗ If indoor units from the Connection unit series are connected within a single refrigerant system to indoor units from any
other series, cooling/heating switchover will not be possible using the remote contoroller of the Connection unit series
indoor units, However, if the remote controller of an indoor unit from the other series is set as a master remote
controller, cooling/heating switchover will be possible.
∗ If all indoor units are from the Connection unit series, an outdoor unit Cool/Heat selector will be needed to enable
cooling/heating switchover.
∗ In case of Heat Recovery System
Cooling/Heating changeover is possible when connecting with BS unit.

� Large liquid crystal screen displays complete operating status.
� Digital display lets you set temperature in 1°C units.
� Lets you individually program by timer the respective times for operation start and
stop within a maximum of 72 hours.
� Equipped with a thermostat sensor in the remote controller that makes possible
more comfortable room temperature control.
� Monitors room temperature and preset temperature by microcomputer, and can
select cool/heat operation mode automatically. (VRV System Heat Recovery
Series only)
� Enables you to select cool / heat / fan operation mode with the indoor remote
controller of your choice without using the cool / heat selector. (VRV System

Note: 1. 2-remote controller control: By connecting two remote controllers to one indoor unit, control may be made
freely from two places.
*2 When using 2 remote controllers, combined use with group remote control adapter is impossible.
2. Group control: A maximum of 16 indoor units may be controlled simultaneously by one remote controller.
3. Remote control: Remote control wiring may be extended to a maximum of 500 m and therefore the indoor unit
may be controlled from 500 m away. (Separate operation wireless remote controller type may be operated
from 200 m away.)
4. Combined control: Combined simultaneous control of the HRV unit with indoor units may be made.
