The frequency judgment will perform every 30 seconds. Nevertheless, the frequency is instructed to outdoor compressor after
every 90 seconds except when either one of the below conditions is met:
(a) The frequency judged changes from frequency number decreasing zones (Zone No. 0 or 1 or 2 or 3) to frequency number
increasing zones (Zone No. 5 or 6 or 7 or 8) and vice verse.
(b) The frequency judged falls on frequency shifting zone number 0 or 1 (shift to Frequency MIN) at Cooling mode operation.
(c) The frequency judged falls on frequency shifting zone number 4 (no shifting in frequency number) at Cooling mode
operation.
(d) The frequency judged falls on frequency shifting zone number 7 or 8 (shift to Frequency MAX) at automatic fan speed.
The instructed frequency is the value referred by the frequency number, which resulted from previous instructed frequency
number with the numbers of frequency numbers to be shifted, in Table on Frequency Number.
