of thermostat's OFF-ON.
In Auto the fan speed is as follows.
Room temperature minus set temperature : 2 degrees or more································High

2. Coil frost prevention
Temperature control
When the indoor coil thermistor RT12 reads 4°C or below(MSC-C07/C09TV) / 0°C or below(MSC-C12TV) for 5 min-
utes, the coil frost prevention mode starts.
The indoor fan operates at the set speed and the compressor stops for 5 minutes.
After that, if RT12 still reads below 4°C (MSC-C07/C09TV) / 0°C (MSC-C12TV), this mode is prolonged until the
RT12 reads over 4°C (MSC-C07/C09TV) / 0°C (MSC-C12TV).
Time control
When the three conditions as follows have been satisfied for 1 hour and 45 minutes, the compressor stops for 3 min-
utes. The indoor fan operates at the set speed.
a. Compressor has been continuously operating.
b. Indoor fan speed is Low or Med..
c. Room temperature is below 26°C.
When compressor stops, the accumulated time is cancelled. When compressor restarts, time counting starts
from the beginning.
Time counting also stops temporarily when the indoor fan speed becomes High or the room temperature exceeds
26°C. However, when two of the above conditions (b.and c.) are satisfied again, time accumulation is resumed.
