Fixing method of the compressor operating frequency
The compressor operating frequency can be fixed by setting the SW2 (a switch of “A Control Service Tool PAC-SK52ST)
and turning on/off the SW5-1 on the controller board. However, the setting may not be fixed to the desired value in case of
a couple of minutes right after the start-up, in case the operating frequency is limited to some extents by various restrictive
controls such as the SW7-3 to 6 settings and in case the operating frequency is set to be out of the operating frequency
range designated for each model. Check the operating frequency on the LED display of the outdoor unit every time the
setting is changed.
w Frequency can be set by the combination of the 6-bit binary digit as shown above. (SW2-1 stands for the lowest bit, and
SW2-6 stands for the upper bit.)
