(3) The indoor heat exchanger restricts revolving
speed of the fan motor to prevent a cold draft. The
upper limit of the revolving speed is shown in
Fig. 7-3-8 and Table 7-3-9.
7-3-5. 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

which the automatic operation has started, as
shown in Fig. 7-3-10. The Fan only operation
continues until the room temperature reaches a
level at which another mode is selected.
(2) Temporary Auto
When the RESET 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. 7-3-10
