Control Specification SiMT041311E49 Function and Control2.4 Input Current ControlOutline The microcomputer calculates the input current while the compressor is running, and sets thefrequency upper limit based on the input current.The input current control is the upper limit control of frequency and takes priority over the lowerlimit control of four way valve operation compensation.DetailFrequency control in each zoneStop zone After 5 seconds in this zone, the compressor is stopped.Dropping zone The upper limit of the compressor frequency is defined as operation frequency – 2 Hz. After this, the output frequency is lowered by 2 Hz every second until it reaches the keepzone.Keep zone The present maximum frequency goes on.Reset zone Limit of the frequency is cancelled.Limitation of current dropping and stop value according to the outdoor temperature The current drops when outdoor temperature becomes higher than a certain level(depending on the model).25 class 35 class 50 classCooling Heating Cooling Heating Cooling HeatingA (A) 21.0 21.0 21.0B (A) 10.0 9.75 10.0 12.75 10.0 14.0C (A) 9.0 8.75 9.0 11.75 9.0 13.0Compressor StopInput currentDropping ZoneStop ZoneKeep ZoneReset Zone(R14643)A(A)BC
