FEATURES
 Microprocessor Controlled Operation The interior compartment of the remote controller c ontains several 
features to facilitate automatic operation, easy lo gically displayed 
for easy use.
 24-Hour ON or OFF Timer This timer can be set to automatically turn the uni t on or off at any 
time within a 24 hour period.
 1-Hour OFF Timer This timer can be set to automatically turn off the  unit at any time 
after one hour.
 Night Setback This function saves energy by controlling operation  to provide a 
quieter operating sound than normal.
 Automatic and 3-step Fan Speed Auto/High/Medium/Low  Air Sweep Control
This function moves a flap up and down in the air o utlet, directing 
air in a sweeping motion around the room and providi ng comfort in 
every corner.
 Automatic Restart Function for Power Failure Even when power failure occurs, preset programmed o peration 
can be reactivated once power resumes.
 Automatic Switching between Cooling and Heating This unit automatically switches between cooling op eration and 
heating operation according to the difference betwe en the room 
temperature and the temperature setting. 
(This function is available only for “Single use” o f COOL/DRY/
HEAT Model.)
 Hot Start Heating System Right from the start, the air is warm and comfortab le. This system 
prevents any cold blasts at the beginning while the  heat pump is 
warming up, or even defrosting. 
(This function is available only for COOL/DRY/HEAT  Model.)
 Since the wired remote controller is designed to b e commonly used for various air conditioners, some  of the functions of the wireless 
remote controller supplied with the indoor unit can not be used.
 “Single use” means that only one indoor unit is con nected with one outdoor unit in a one-unit-to-one-unit configuration.
 “Multiple use” (i.e. Flexi-Multi system) means that  two or more indoor units are connected with one ou tdoor unit in a multiple-unit-to-one-unit 
configuration.

INSTALLATION LOCATION
We recommend that this wired remote controller be  
installed properly by qualified installation techni cians 
in accordance with the Installation Instructions 
provided with the unit. 
Avoid:  
To protect the air conditioner from heavy corrosion , avoid installing 
the outdoor unit where salty sea water can splash d irectly onto it or 
in sulphurous air near a spa.
ELECTRICAL REQUIREMENTS
1. All wiring must conform to the local electrical cod es. 
Consult your dealer or a qualified electrician for  details.
2. Each unit must be properly grounded with a ground ( or 
earth) wire or through the supply wiring.
3. Wiring must be done by a qualified electrician.
Pull off the power plug from a receptacle, or switc h off the breaker, or 
switch off the power disconnecting mean to isolate  the air conditioner 
from the main power supply when not in use for a lo ng time.
SAFETY INSTRUCTIONS
 Read this Instruction Manual carefully before usin g 
this air conditioner. If you still have any difficu lties 
or problems, consult your dealer for help.
 This air conditioner is designed to give you 
comfortable room conditions. Use this only for its  
intended purpose as described in this Instruction 
Manual.  Do not install this wired remote 
controller where there are fumes or  
flammable gases, or in an extremely  
humid space such as a greenhouse.
 Do not install the wired remote 
controller where excessively high  
heat-generating objects are placed.
 Confirm to authorized dealer or specialist on usag e of 
specified refrigerant type. 
Using of refrigerant other than the specified type  may cause 
product damage, burst and injury etc.
 Never touch the unit with wet hands. 
 Never use or store gasoline or other flammable vap or or 
liquid near the air conditioner — it is very dangerous.
