USIING THE REMOTE CONTROL UNIT OPERATION
HOW TO INSTALL BATTERIES
Remove the lid in the rear part of the remote control unit.
Insert two AAA alkaline batteries of 1,5 V-DC.Make sure to insert the batteries
according to the polarity(+/-) marked in the battery compartment.
Push the lid back on.
General Note:
Replace the batteries when the remote control unit display fails to light, when the air
conditioner does not receive the remote control unit signals or when the low battery icon
is displayed.
Remove the batteries if you do not use the remote control unit for more than one
month.
The batteries last about six months, depending on how much you use the remote
control unit.
The batteries of the remote control contain polluted substances Exhausted batteries
must be disposed according to local laws.
TEMPERATURE SENSOR SELECTOR
OPERATION WITH THE REMOTE CONTROL UNIT
Under normal conditions the room temperature is detected and checked by the
temperature sensor placed in the air conditioner.
Press the remote control I FEEL button to activate the temperature sensor placed in
the remote control. This function is designed to provide a personalised environment
by transmitting the temperature control command from the location next to you.
Therefore, in using this function, the remote control should always be aimed,
without obstruction, at the air conditioner.
Check that the circuit breaker on the power panel is turned ON and the STANDBY lamp
is light up.
When using the remote control unit, always point the unit transmitter head directly at the
air conditioner receiver.
HOW TO TURN ON THE AIR CONDITIONER
Press the ON/OFF button to turn the air conditioner on. The indicator OPERATION
will light up, indicating the unit is in operation.
HOW TO REMOVE BATTERIES
Remove the lid in the rear part.
Remove the other battery in the same way.
Press the battery toward the negative end and lift it out by its positive end as shown.
1. Press the CLOCK button. The time indication alone flashes.
2. Press the + or - buttons until the present time is displayed.
3. Press the CLOCK button to stop the indication flashing.
HOW TO SET THE PRESENT TIME

COOLING
Verify that the unit is connected to the main
power and the STANDBY lamp is lighted up.
1. Set the MODE selector to COOL .
2. Press the ON/OFF ( ) button and switch the
airconditioner ON.
3. Press the - or +. buttons to set the desired
temperature The temperature range is between
16and 30(61-86 F).
THE DISPLAY SHOWS THE
SELECTED TEMPERATURE..
4. Press the FAN SPEED button to select the fan
speed.
1. Set the MODE selector to HEAT .
2. Press the ON/OFF button and switch the air condioner ON.
3. Press the + or -. buttons to set the desired temperature, the temperature range is
between 16 and 30(61-86F).
( )
4. Press the FAN SPEED button to select the fan speed.
NOTE
For several minutes after the start of heating operation, the indoor fan will not run until
the indoor heat exchanger coil has warmed up sufficiently. This is because the COLD
DRAFT PREVENTION SYSTEM is operating.
DEFROSTING OF HEAT EXCHANGE / OUTDOOR UNIT “STANDBY”
When the outdoor temperature is low, frost or ice may appear on the heat
exchanger coil,reducing the heating performance. When this happens, a
microcomputer defrosting system operates. At the same time, the fan in the
indoor unit stops until defrosting is completed. Heating operation restarts after
several
minutes. (This interval will vary slightly depending on the room and
outdoor temperature).
HEATING PERFORMANCE
A heat pump air conditioner heats a room by taking heat from outside air. The
heating efficiency will reduce when the outdoor temperature is very low.
THE DISPLAY SHOWS THE
SELECTED TEMPERATURE..
HEATING
AUTOMATIC OPERATION
1. Set the MODE selector to AUTO .
2. Press the ON/OFF ( ) button and switch the air conditioner ON.
3. Press the + or -. buttons to set the desired temperature (The temperature range is
between 16 and 30(61-86F).
OPERATION OPERATION
THE DISPLAY SHOWS THE
SELECTED TEMPERATURE.
When this setting is selected, the air conditioner calculates the difference between the
thermostat setting and the room temperature and automatically switches to the COOL,
DRY or HEAT mode as appropriate.
4. Switch the FAN SPEED selector button to the setting you want.
18 19
OPERATION OPERATION
AUTOMATIC
Simply set the FAN SPEED selector to the position . A microcomputer
automatically controls the fan speed when the AUTO mode is selected. When the air
conditioner starts operating, the difference between the room temperature and the set
temperature is detected by the microcomputer which then automatically switches the
fan speed to the most suitable level.
MANUAL
If you want to manually adjust speed just set the FAN SPEED selector as desired.
Each time the button is pressed, the fan speed is changed in sequence:
