(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 one minute from the time when Tc enters zone E shown in the figure in No.7 below.
(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.
