. Automatic operation
([MODE] button on the remote control is set
to the automatic operation.)
(1) One of 3 operations (Cooling, Fan only or Heating)
is selected according to difference between the
preset temperature and the room temperature at
which the automatic operation has started, as
shown in Fig. 7-2-8. The Fan only operation
continues until the room temperature reaches a
level at which another mode is selected.
(2) Temporary Auto
When the [TEMPORARY] button on the indoor unit
is pushed, the preset temperature is fixed at 24 °C
and the indoor unit is controlled as shown in
Fig. 7-2-8.

. High-Temperature Limit Control
*Heat pump model only
The microcontroller detects the indoor heat exchanger
temperature to prevent pressure of a refrigerating cycle
from increasing excessively.
The compressor and outdoor fan motor are controlled
as shown in Fig. 7-3-1.
