Air speed selection
Outline of specifications
1) Operation [HH], [L] or [AUTO] is performed by command
from the remote controller.
2) The air speed is varied with difference between Ta and
Ts while the air speed is set to [AUTO].
<COOL>
Remarks
HH > L > UL
<HEAT>
3) If thermostat is turned off during heating operation, the
mode changes to [UL] or [STOP].
4) If Ta ≥ 25°C when the heating operation has started or
when defrost operation has been cleared, the air
conditioner operates with [L] mode or higher mode for
1 minute after Tc entered in A zone of the cooling air
discharge preventive control (Item 7).
5) In automatic cooling/heating operation, the mode enters
in [AUTO].
STOP operation is the
cooling air discharge
preventive control by Tc.
Tc: Indoor heat

Display: [AUTO]
7 Cool air discharge
preventive control
1) In heating operation, the indoor fan is controlled based
on the detected temperature of Tc sensor or Tcj sensor.
As shown below, the upper limit of the revolution
frequency is restricted.
However B zone is assumed as C zone for 6 minutes and
after when the compressor activated.
In defrost operation, the control value of Tc is shifted by
6°C.
In D zone, the priority is
given to air speed
selection setup of
remote controller.
In A and B zones while
thermo is ON,
[PRE-HEAT
(Heating ready)] is
displayed.
