*1 The preset temperatures for cooling and heating can be set under the following conditions.
• The cooling preset temperature is greater than the heating preset temperature.
• The difference between the cooling and heating preset temperatures is equal or greater than the minimum temperature difference that varies depending on the indoor
unit model to be connected.
Note:
Even if you press the ON/OFF button immediately after shutting down the operation is progress, the air conditioner will not start for about 3 minutes.
This is to prevent the internal components from being damaged.
3.2. Mode Selection
Each pressing of the [F1] button cycles
through the following operation modes.
Select the desired operation mode.

What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same 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 2 °C, 4 °F or more above the set temperature for 15 minutes,
the air conditioner switches to cool mode. In the same way, if the room
temperature remains 2 °C, 4 °F or more below the set temperature for
15 minutes, the air conditioner switches to heat mode.

■
Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed a
few degrees warmer and heating operation is performed a few degrees
cooler than the set room temperature once the temperature is reached
(automatic energy-saving operation).
