8-4. Cool air discharge preventive control
In heating operation, the indoor heat exchanger
restricts revolving speed of the fan motor to prevent a
cold draft. The upper limit of the revolving speed is
shown in Fig. 8-4-1 and Table 8-4-1.
NOTES :
*1: The fan stops for 2 minutes after thermostat-OFF.

°
C when the preset temperature is 24
°
C or
more and A is the preset temperature when it is
under 24
°
C.
*3: SUL means Super Ultra Low.
*4: Calculated from difference in motor speed
between SUL and HIGH.
