8.1. BASIC FUNCTION
8 Operation Details
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjust output power for maximum comfort always. In order to achieve the suitable operating mode, the
microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature
shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that
judging the condition according to internal setting temperature and intake air temperature.
8.1.1. Internal Setting Temperature
Once the operation starts, remote controller setting temperature will be taken as base value for temperature shifting processes.
These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value
will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

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 E9CKP and E12CKP/E15CKP 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).

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.
