OPERATING TIPS
Instructions relating to heating are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Mode operation: AUTO
COOLING MODEL
•When the room temperature is 4 °F higher than the set temperature, the mode will switch between Cooling and Drying.
•During the Drying mode operation, the FAN setting should be switched to LOW for a gently cooling effect during which the fan may temporarily stop rotating.
HEAT & COOL MODEL (Reverse Cycle)
Auto changeover function
• When AUTO CHANGEOVER is selected, the air conditioner |
selects the appropriate operation mode (Cooling or Heat- |
ing) according to your room’s present temperature. |
• When AUTO CHANGEOVER is first selected, the fan will |
operate at a very low speed for about 1 minute while the |
unit determines the current conditions of the room and |
selects the proper operation mode. |
• When the room temperature is near the thermostat set- |
Energy save
•The energy conservation mode (ENERGY SAVE) raises the set temperature slightly in the cooling mode and lowers the set temperature in the heating mode to economically control the operation of the unit.
•If you press the ENERGY SAVE button while the unit is in the timer mode, the unit will go into the conservation mode when the unit starts with the timer.
•If you turn off the air conditioner while in the conservation mode, the mode will be shut off.
•The temperature set on the remote controller will not change if the energy save mode is used.

pressed, the thermostat setting | 80°F | |

ting, the air conditioner will begin monitor operation. In |
the monitor operation mode, the fan will operate at a very |
low speed. If the room temperature subsequently changes, |
the air conditioner will once again select the appropriate |
operation (Heating or Cooling) to adjust the temperature |
to the value set in the thermostat. (The monitor operation |
range is ±4 °F relative to the thermostat setting.) |
Fan speed: AUTO
During heating operation
When the ENERGY SAVE is pressed, the thermostat setting is automatically lowered 2 °F every 30 minutes, until the ther- mostat is lowered a total of 4 °F.

Heating: The fan will operate at very low speed when the tem- perature of the air issued from the indoor unit is low.
Cooling: As the room temperature approaches that of the set temperature, the fan speed becomes slower.
Fan: The fan alternately turns on and off; when on, the fan runs at the low fan speed.
AUTO restart
•Should the power supply to the air conditioner be inter- rupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.
•Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily turn off the circuit breaker turn it on again and then use the remote controller to resume operation.

Hot start (for heating)
The indoor unit prevents cold drafts when heating operation begins.
The indoor unit fan will not operate or it will operate at a very low speed until the heat exchanger reaches the set tempera- ture.
Defrosting (for heating)
When the outdoor temperature is low and the humidity high, frost will collect on the outdoor unit, reducing heater efficiency. When this happens, the computer will automatically start the defrost cycle. During the defrost cycle, the indoor fan will shut-
down and 
will be displayed on the remote controller. It will take anywhere from 4 to 15 minutes before the air condi- tioner starts up again.
Group Control
One remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same set- tings.
Dual Remote Controllers (optional)
An additional remove controller can be added up to the maxi- mum of two remote controllers. Either remote controller can control the air conditioner. However, the timer functions can- not be used at the slave unit.
