lected during heating, cooling or dehumidifying operation, the unit is operated in the previous operation mode.
(d) Setting temperature can be adjusted within the following range. There is the relationship as shown below between the sig-
nals of the wireless remote control and the setting temperature.
(e) When the unit is operated automatically with the wired remote control connected, the cooling operation is controlled ac-

during heating.

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
judgment of operation mode is cancelled.
If the setting temperature is changed with the wireless remote control, the operation mode is judged immediately.
