2.3.8. Centralized draining method
•
• •
•
Even when multiple outdoor units are installed to a wall, the
drain outlets can be concentrated into a single drain pipe.
This makes installation easier and also improve
appearance.
2.4. A brand-new control method
1.
Easier power supply wiring connection
Power supply wiring and other wiring tasks can be carried out more easily.
•
• •
•
Twin non-polar wires used to connect indoor and outdoor units.
•
• •
•
Adoption of connection error prevention circuits for drive wires and signal wires. If a connection error is made, the relay does
not operate and current does not flow to the circuit boards.
2.
Twin and Triple operation
•
• •
•
Simultaneous air conditioning of wide spaces and corners is possible. Indoor units of different horsepowers can even be
used in combination.
•
• •
•
Master unit and slave-units can be set automatically in twin and triple systems. No address setting is necessary.
•
• •
•
Multiple indoor units can be operated simultaneously with a single remote control. Note that individual operation is not
possible.
3.
Separate indoor/outdoor unit power supplies
The power supply can be connected to (1) just the outdoor units, or (2) to both the indoor and outdoor units.
4.
Easy test operation
Test operation can be carried out for both indoor and outdoor units.
5.
Automatic setting initialization function
(Remote control and Indoor unit)
In accordance with the indoor and outdoor units connected and the connection methods, conditions such as the connection
configuration (twin or triple format) and remote-control functions such as automatic louvre operation and cooling or heating
mode are automatically detected and set instantly.
