8.1.2. Frequency Instruction for Compressor Operation
Operation of compressor is based on instructed frequency, continuously from indoor unit´s microcomputer after performing
temperature sampling and judgment.
There are total 30 different frequency values, which listed as Table on Frequency Number, to be instructed based on the
temperature judgment

For normal start of operation, including Thermo-OFF, Deice-Resuming, and remote controller ON-OFF starts, the compressor
starts to operate at frequency no. 8, values of 30Hz and 32Hz for E9BKP and E12BKP respectively, for 60 seconds.
The frequency to be judged and instructed, however, starts to judge once the air conditioner operated and the judgment will
continue every 30 seconds until it is stopped by all kinds of compressor off conditions. This judgment is based on the internal
temperature sampling that involving internal setting temperature and intake air temperature.
From the internal sampling, the temperature different (intake air temperature - internal setting temperature) will be used to judge
the Zone on which the frequency to be instructed for the initial operation of compressor (refer to Table on Initial Frequency Zone).

After the initial operation, the instructed frequency will change or shift from initial frequency according to the judgment on
temperature different from sampling (refer to the Table on Shifting Frequency Zone).
