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. De-
pending 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.

According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
During automatic operation, if the room temperature changes and
remains 1.5 °C, 4 °F or more above the set temperature for 3 minutes,
the air conditioner switches to cool mode. In the same way, if the room
temperature remains 1.5 °C, 4 °F or more below the set temperature for
3 minutes, the air conditioner switches to heat mode.

Press the [F1] or [F2] button to move the cursor to the desired
temperature setting (cooling or heating).
Press the [F3] button to decrease the selected temperature, and
press the [F4] button 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.
