8 Cold Draft Prevention (Heating)

• This function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat

exchange coil have sufficiently warmed up.

• When 10 minutes has elapsed, the fan speed is automatically switched to set speed regardless of indoor heat

exchange coil temperature.
