Drying mode
•
The indoor fan turns to the low-speed operation, disabling the change of fan
speed.
•
Dry operation cannot be carried out at room temperature of less than 18°C.
•
The dry is a microcomputer-controlled dehumidifying operation which controls
excessive air-cooling according to the room temperature of your choice. (Not
usable for heating.)
1. Until reaching room temperature of your choice
The compressor and indoor fan function is linked motion according to the
change of the room temperature and automatically repeat ON/OFF.
2. When reaching room temperature of your choice
Both the compressor and indoor fan stop.
When stop continues for 10 minutes, the compressor and indoor fan are
operated for 3 minutes to keep the humidity low.

Displayed only during the defrosting operation.
"STAND BY" display
Displayed from the start of heating operation until the moment warm air blows out.
Caution:
•
Never expose your body directly to cool air for a long time. Excessive
exposure to cool air is bad for your health, and should therefore be
avoided.
•
When the air-conditioner is used together with burners, thoroughly
ventilate the area. Insufficient ventilation can result in accidents due to
oxygen deficiency.
•
Never place a burner at a place where it is exposed to the airflow from
the air-conditioner. Doing so can result in imperfect combustion of the
burner.
•
The microcomputer functions in the following cases:
- Air does not blow out when heating starts.
• To prevent any cool air from escaping, the indoor fan is gradually switched
in sequence from faint airflow/weak airflow/set airflow according to the
temperature rise of the blown out air. Wait a moment until the airflow
comes out naturally.
- The fan is not moving at the set speed.
• In some models, the system switches over to faint airflow when the
temperature of the room reaches the set temperature. In other cases,
it stops to prevent any cool air from escaping during the defrosting
operation.
- Air flows out even if operation is stopped.
• Approximately 1 minute after the stop of operation, the indoor fan
sometimes rotates to eliminate extra heat generated by the electric heater,
etc. The fan speed comes to low or high.
Auto (dual set point) and Setback modes
When the operation mode is set to the Auto (dual set point) mode or the Setback
mode, two set temperatures (one each for cooling and heating) can be set.
Depending on the room temperature, indoor unit will automatically operate in
either the cooling or heating mode and keep the room temperature within the
preset range.
Differences between the two modes
•
Auto (dual set point) mode
The set temperatures that are specified for the Cool/Drying mode and the Heat
mode will be used to automatically control the room temperature to stay within
the set temperatures. This mode is especially effective during the in-between
seasons, when the temperature difference between the highest and the lowest
is large and both heating and cooling modes are used within the same day.

Setback mode
Room temperature is controlled to stay within the set temperature range that
is specified for the Setback mode. By leaving sufficient temperature differential
between the set temperature for cooling (upper limit) and heating (lower limit),
it is possible to keep the room temperature within the specified range without
overworking the air conditioners. This setting will be especially effective during
periods of non-occupancy.

*1 The settable temperature ranges vary, depending on the indoor unit model.
*2 The set temperature for Auto mode (either single or dual set point(s)) will ap-
pear depending on the indoor unit model.
*3 The same values are used for the set temperature for Cool/Drying mode and
the cooling set temperature for Auto mode (dual set points). Likewise, the
same values are used for the set temperature for Heat mode and the heating
set temperature for Auto mode (dual set points).
*4 The cooling and heating set temperatures can be set under the following
conditions.
- The cooling set temperature is greater than the heating set temperature.
- The difference between the cooling and heating set temperatures is equal or
greater than the minimum temperature difference that varies with the indoor
unit model.
