Stops operation if no rotation pulse signal 
is input from the indoor fan motor for one 
minute.

Stops operation if the rotation pulse signal 
from the indoor fan indicates low rpm 
(approximately 300 rpm or less).

Lowers the operating frequency if the 
temperature of the indoor heat exchanger 
goes below 5

°C during cooling. Stops the 

compressor if the temperature stays below 
0

°C for 4 minutes.

Lowers the operating frequency if the 
temperature of the indoor heat exchanger 
rises above the overheating temperature 
during heating. Stops the compressor if the 
temperature stays above the overheating 
temperature for 1 minute at minimum 
frequency or less.
Set values for overheating temperature

During normal operation: 45

°C to 54°C

During full power operation: 47

°C to 

58

°C

Stops the compressor if a current of 
approximately 23A or more flows in the 
power transistor module. 

Lowers the operating frequency if the 
compressor AC current exceeds 
set value(   ).Show "2-2(1)AC peak 
control"
Stops the compressor if the current 
exceeds at 40Hz or less set value(   ).

Lowers the operating frequency if the 
temperature of the compressor chamber 
thermistor (TH1) rises above 105

°C.

Stops the compressor if the thermistor 
stays above 105

°C for 1 minutes at 

minimum frequency or less.

Stops the compressor if the compressor 
chamber thermistor is above 114

°C.
