•
• •
• Additional refrigerant charging unnecessary for 10 m
−
− −
− All models do not require any additional charging of
refrigerant for 10 m of pipe length. This makes
installation much easier.
•
• •
• Drain water dripping-prevention structure
−
− −
− The base of the outdoor unit is provided with a single
drain hole in order to prevent drain water from leaking
out of the unit. By connecting a drain elbow and a
discharge pipe, water leakages can be prevented even
when the unit is installed to a wall.
•
• •
• Long pipe design for refrigerant pipes
−
− −
− Maximum piping length of 25m for all models.
2.10. A brand-new control method
using the latest in technology
•
• •
• 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.
•
• •
• 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.
•
• •
• 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.
•
• •
• Easy test operation
Test operation can be carried out for both indoor and
outdoor units.
•
• •
• 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.
2.11. Wired Remote Control
•
• •
• The new design includes an easily-visible red pilot lamp.
The power can be turned on and off at a single touch,
without opening the cover.
•
• •
• Has a build-in thermistor, allowing indoor temperature
detection in accordance with indoor conditions by switching
with main unit thermistor.
•
• •
• Twin non-polar wires make installation work easy. (10 m
cable supplied as accessory.)
