8.1.2. Frequency Instruction for Compressor OperationOperation of compressor is based on instructed frequency, continuously from indoor unit´s microcomputer after performingtemperature sampling and judgment.There are total 30 different frequency values, which listed as Table on Frequency Number, to be instructed based on thetemperature judgmentTable on Frequency NumberNo. Frequency (Hz) RemarksE9CKP E12CKP/E15CKP1 12.0 12.0 Freq.

This judgment is based on the internaltemperature 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 judgethe Zone on which the frequency to be instructed for the initial operation of compressor (refer to Table on Initial Frequency Zone).Table on Initial Frequency ZoneTemperature, X (°C) Zone Freq.
