2-2 Frequency control
(1) AC current peak control
(2) Control for prevention of indoor heat exchanger overheating. If the temperature of the indoor heat exchanger
exceeds the overheating prevention line 1 or 2 during heating, the operating frequency is lowered by approximately
5 to 10 Hz. After that, the frequency is lowered by approximately 5Hz once every 60 seconds or 10 Hz once every
120 seconds. When the temperature of the indoor heat exchanger goes below the overheating prevention line 1,
the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored.
If the frequency is lowered to minimum frequency without the temperature of the outdoor heat exchanger
decreasing and this condition lasts for 1 minute, the compressor will be stopped.
(3) Control for prevention of outdoor heat exchanger overheating. If the temperature of the outdoor heat exchanger
exceeds the overheating prevention lone 1 or 2 during cooling, the operating frequency is lowered by approximately
5 to 15 Hz.
After that, the frequency is lowered by approximately 5 once every 60 seconds or approximately 15Hz once every
120 seconds. When the temperature of the outdoor heat exchanger goes below the overheating prevention clear
line, the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored. If the
frequency is lowered to minimum frequency without the temperature of the outdoor heat exchanger decreasing and
this condition lasts for 1 minute, the compressor will be stopped.
4) Control for prevention of discharge overheating
If the discharge temperature exceeds approximately (AU-X13BE:101°C except AU-X13BE:105°C) during compressor
operation, the operating frequency is lowered by approximately 5 Hz. After that, the frequency is lowered by
approximately 5 Hz once every 60 seconds. When the discharge temperature goes below approximately (AU-
X13BE:100°C except AU-X13BE:104°C) , the frequency is raised by approximately 5 Hz once every 60 seconds,
and normal operation is restored.
If the frequency is lowered to minimum frequencywithout the discharge temperature decreasing and this condition
lasts for 1 minute, the compressor will be stopped.
