Cold Draft Prevention - Sanyo SAP–KR184GJH Technical & Service Manual

8-5. 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.
Indoor fan speed varies according to the indoor heat exchange coil temperature as table shown below.
Condition
Compressor is in operation
(Indoor coil temp. goes up)
Compressor is stopped
(Indoor coil temp. goes down)
NOTE
1 When the coil temperature rises above 36°C, indoor fan operates in set speed. At the same time,
standby lamp on front of the indoor unit lights OFF.
2 If 10 minutes has elapsed after the compressor has been stopped, the indoor fan stops its operation
regardless of the indoor heat exchange coil temperature.
