9-2-5. Cold Draft Prevention in Heating
At the beginning of the heating operation, the fan does not start or else operates at LL speed.
As the temperature of the indoor heat exchanger rises, the fan operates at the set speed.
High speed
Very low speed
NOTE
The fan speed is set to FORCED LL mode within 30 seconds following thermo OFF.
Normal operation means operation when the room temperature and set temperature are close.
When Heating operation is starting, the indoor fan will not operate until the temperature of the heat exchanger
rises to over approximately 20°C.
9-2-6. Compressor Discharge Temperature Control
This function controls the operating frequency to prevent the compressor discharge temperature from rising more
than a specified temperature.

(a) Area — the air conditioner follows auto performance
control.
(b) When the temperature rises above point A, the operat-
ing frequency is reduced at a specified rate.
(c) Area — further frequency rise is not allowed.
(d) When the temperature falls below point B, prevention of
a rise in frequency is released and the air conditioner
operates as in (a).
