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

Stops the compressor if a current of
approximately 47/26A or more flows in the
power transistor module. Also stops the
compressor if the temperature of the
power transistor module is exceeds 105
°
C.
Lowers the operating frequency if the
compressor AC current exceeds
set valve( ).Show "2-2(1)AC peak control"
Stops the compressor if the current
exceeds at 40Hz or less set valve( ).
Stops the compressor if the compressor
AC current exceeds (AE-X08BE-C/AE-
X10BE-C: 26A, AE-X13BE: 47A)
immediately after activating the
compressor (in 6 seconds).
