Inverter principle to regulate the capacity a frequency control is needed the inverter makes it possible to vary the rotation speed of the compressor the following table explains the conversion principle 37

Main control parameters the compressor is frequency controlled during normal operation the target frequency is set by the following 2 parameters coming from the operating indoor unit 37

Main functions 37

Note see the list of functions for the functions applicable to different models 37

The difference between the room temperature and the set temperature 37

The load condition of the operating indoor unit 37

The target frequency is adapted by additional parameters in the following cases 37

Comfortable air conditioning a detailed adjustment is integrated to ensure a fixed room temperature it is possible to air condition with a small room temperature variation 38

Energy saving heating and cooling once the set temperature is reached the energy saving operation enables to maintain the room temperature at low power 38

Even during extreme cold weather the high capacity is achieved it is maintained even when the outside temperature is 2 c 38

For more information refer to forced operation mode on page 38

Forced cooling operation 38

Frequency limits the following table shows the functions that define the minimum and maximum frequency 38

Inverter features the inverter provides the following features 38

Quick heating and quick cooling the compressor rotational speed is increased when starting the heating or cooling this enables a quick set temperature 38

The regulating capacity can be changed according to the changes in the outside temperature and cooling heating load 38

Power airflow dual flaps wide angle louvers and auto swing 39

Fan speed control for indoor units 40

In case of inverter units the microcomputer automatically sets the temperature and fan settings the difference between the room temperature at startup and the temperature set by the microcomputer is divided into two zones then the unit operates in the dry mode with an appropriate capacity for each zone to maintain the temperature and humidity at a comfortable level 41

Programme dry function 41

Programme dry function removes humidity while preventing the room temperature from lowering since the microcomputer controls both the temperature and air flow volume the temperature adjustment and fan adjustment buttons are inoperable in this mode 41

The motions for example in cooling 46

This is the function that detects existence of humans in the room by a human motion sensor intelligent eye and reduces the capacity when there is no human in the room in order to save electricity 46

This sensor detects human motion by receiving infrared rays and displays the pulse wave output 46

When a microcomputer doesn t have a signal from the sensor in 20 minutes it judges that nobody is in the room and operates the unit in temperature shifted 2 c from the set temperature cooling dry 2 c higher heating 2 c lower and auto according to the operation mode at that time 46
