*It can be set the indoor fan motor off or the heating thermostat OFF with connecting a wired remote control.
In the case, indoor air temperature is detected by sensor on the wired remote control.
During the heating operation, the indoor fan speed can be controlled based on the temperature of the indoor heat
exchanger (Th2) to prevent blowing out of cold air.

When both the indoor and the outdoor air temperatures are in the range “A”, cooling or heating is switched depending on
the difference between the setting temperature and the indoor air temperature.
When the operation mode has been judged following the change of setting temperature with the remote control, the hourly j-
udgment of operation mode is cancelled.
(e)
When the unit is operated automatically with the wired remote control connected, the cooling operation is controlled according to
the display temperatures while the setting temperature is compensated by 1 during dehumidifying or by 2 during heating.
