7.5 Cooling Mode

7.5.1 After starting, the operation frequency of compressor submits to following rule.
When the machine is running and ΔT(=room temp. – setting temp.) changes, the frequency of compressor will
rise or descend a grade (7 minutes after starting).
After start, if ΔT stays in a zone for 3 minutes, the frequency will change as follow:
Zone A : Current frequency rise a grade till the maximum grade.
Zone B: Elevate or keep or descend the frequency of compressor.
Zone H: Compressor stops after running as the minimum frequency for 60 minutes or ΔT is less than -2℃.
