•
Compressor OFF temperature = compressor ON temperature.
•
The operation frequency changes every 30 seconds.
•
When the difference of the intake air temperature and Internal setting temperature is -1.5°C or more, compressor will
operate at Fh continuously for 3 minutes and then change over to Fhmax.

•
When the compressor stops, it will not start operation for 3 minutes. (Time Delay Safety Control)
•
When the intake air temperature decreases to the compressor ON temperature, the compressor starts immediately.
•
When the compressor stops, the outdoor fan motor stops 30 seconds later.

(i) Indoor Fan Control
Indoor fan speed and airflow direction varies in accordance to the indoor heat exchanger temperature as shown below:
Indoor fan speed and airflow direction varies in accordance to the indoor heat exchanger temperature as shown below:
Note:
•
UP means fan speed is increased by 1 rank.
•
DOWN means fan speed is decreased by 1 rank.
•
Max means fan speed is running at maximum auto fan speed.
•
Temperature in ( ) is indicating when powerful mode is selected.

(ii) Hot Start
•
At the start of heating operation, the indoor fan stops and compressor operates at Fhmax frequency 99Hz (CS-G95KE) or
115Hz (CS-G125KE). This is to heat up the indoor heat exchanger in order to avoid cold air discharged.
115Hz (CS-G125KE). This is to heat up the indoor heat exchanger in order to avoid cold air discharged.
•
Hot Start ends when
a. Indoor heat exchanger temperature reaches over 15°C
or
b. 4 minutes after heating operation starts.
•
After Hot Start operation, compressor operates at Fhmax 99Hz (CS-G95KE) or 115Hz (CS-G125KE) for 2 minutes.
(iii) Vertical and Horizontal Airflow Direction Control
•
Vertical and horizontal airflow direction control is in accordance to indoor heat exchanger temperature.
The control is valid for automatic airflow direction only.
C. Deice Operation
Deice operation occurs when the deice operation starting signal is generated. This happens when one of the following
conditions occurs. However, the first deice operation will begin 1 hour after start of heating operation.

Deice Operation Time Chart
•
Compressor frequency is set at 40Hz (CU-G95KE) or 49Hz (CU-G125KE) when the deice operation starting signal is generated.
•
30 seconds later deice operation starting signal is generated, indoor fan, outdoor fan, 4-way valve are turned off and
compressor operates at 40Hz (CU-G95KE) or 49Hz (CU-G125KE) for 30 seconds. (Deice operation starts)
compressor operates at 40Hz (CU-G95KE) or 49Hz (CU-G125KE) for 30 seconds. (Deice operation starts)
•
During deice operation, the compressor operating frequency is set at 58Hz (CU-G95KE) or 83Hz (CU-G125KE).
•
Deice will end when the outdoor heat exchanger temperature rises to 16°C or after 11 minutes.
