AT Execute/Cancel
• Selects the limit cycle of MV change width (40% or 100%) for execution. After AT
execution, the "PID" and the "LBA detection time" (LBA: Loop Break Alarm)
parameters are set automatically.
Function
• During heating and cooling control, only 100%AT can be executed.
• When this parameter is selected, the setting becomes [
