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 or Tcj is shifted
by 6°C.
In D and E zones, the
priority is given to air
volume selection
setup of remote
controller.

3) When thermo sensor turns OFF during heating, the fan
speed mode becomes UL ( weak).
4) When Ta is 25°C or above at the beginning of HEAT
operation or when canceling defrost mode, H or HH mode
continues for 1 minute from the time when Tc enters zone
E. (Following figure.)
5) The HH fan speed for auto cooling/heating is set to a
speed higher than that for normal cooling/heating.
However, it varies depending on the temperature difference
of Tc during auto heating.
