Press the [F3] button to decrease the selected temperature, and [F4]
to increase.
• Refer to the table on page 6 for the settable temperature range for
different operation modes.
• The preset temperature settings for cooling and heating in the Auto
(dual set point) mode are also used by the Cool/Drying and Heat
modes.
• The preset temperatures for cooling and heating in the Auto (dual
set point) mode must meet the conditions below:
• Preset cooling temperature is higher than preset heating temperature.
• The minimum temperature difference requirement between cooling and
heating preset temperatures (varies with the models of indoor units
connected) is met.
* If preset temperatures are set in a way that does not meet the minimum
temperature difference requirement, both preset temperatures will
automatically be changed within the allowable setting ranges.

<Auto operation (dual set point) mode>
When the operation mode is set to the Auto (dual set point) mode, two
preset temperatures (one each for cooling and heating) can be set.
Depending on the room temperature, indoor unit will automatically
operate in either the Cool or Heat mode and keep the room temperature
within the preset range.
The graph below shows the operation pattern of indoor unit operated in
the Auto (dual set point) mode.

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.

Each pressing of the [F4] button cycles through the following fan speeds.
Speed 1
• The available fan speeds depend on the models of connected indoor units.
Note:
The number of available fan speeds depends on the type of unit
connected. Note also that some units do not provide an "Auto" setting.
In the following cases, the actual fan speed generated by the unit will differ
from the speed shown the remote controller display.
1. While the display is showing "STAND BY" or "DEFROST".
2. When the temperature of the heat exchanger is low in the heat mode.
(e.g. immediately after heat operation starts)
3. In HEAT mode, when room temperature is higher than the temperature setting.
4. In COOL mode, when room temperature is lower than the temperature setting.
5. When the unit is in Drying mode.
