4. Cooling mode operation
• Operating frequency of compressor depend on the difference of the temperature.
(= intake air Temp.- Compressor off Temp.
• Compressor off temp.= setting temp.
-
0.5°C
on temp. = setting temp. +0.5°C
• If compressor operates at some operating frequency, the operating frequency of compressor cannot be
changed within 30 seconds.
• Condition of compressor turned off
- When intake air temperature stay at the temperature between setting temp.
-
0.5°C and setting temp.
-
1.0°C for 3 minutes continuously.
- When intake air temperature reaches below the temperature of setting temp.
-
1.0°C.
• Compressor 2 minutes delay
- The compressor can restart minimum 2 minutes later after compressor off.
