2.16.2 Command Rotation
Cut in upon termination of Starting Control.
Achieve capacity control by controlling the compressor rotation based on:
• Temperaturedifferencebetweensetandroomtemperature,∆T.
• Limit Rotation.
• Defrost control.
2.16.3 Fuzzy Control (Applicable for ARXN/RXN50/60L)
Based on temperature difference, ∆T, current fan speed setting & current indoor operating mode at every 30
seconds interval.
Temperature Difference
Use to set target for compressor frequency change
Compressor frequency is increased or decreased
