Part 4 function and control 40
Additional control parameters 41
Drawing of inverter the following drawing shows a schematic view of the inverter principle 41
Forced cooling operation 41
Frequency principle 41
Frequency restrictions 41
Initial settings 41
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 41
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 41
Main functions 41
Note see the list of functions for the functions applicable to different models 41
The difference between the room temperature and the set temperature 41
The load condition of the operating indoor unit 41
The target frequency is adapted by additional parameters in the following cases 41
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 42
Energy saving heating and cooling once the set temperature is reached the energy saving operation enables to maintain the room temperature at low power 42
Even during extreme cold weather the high capacity is achieved it is maintained even when the outdoor air temperature is 2 c 42
Forced cooling operation for more information refer to forced operation mode on page 42
Frequency limits the following table shows the functions that define the minimum and maximum frequency 42
Inverter features the inverter provides the following features 42
Quick heating and quick cooling the compressor rotational speed is increased when starting the heating or cooling this enables a quick set temperature 42
The regulating capacity can be changed according to the changes in the outdoor air temperature and cooling heating load 42
Airflow direction control 43
Fan speed control for indoor units 44
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 45
Programme dry function 45
Programme dry function removes humidity while preventing the room temperature from lowering since the microcomputer controls both the temperature and airflow volume the temperature adjustment and fan adjustment buttons are inoperable in this mode 45

Details 49
Econo mode 49
Econo mode can be activated while the unit is running the remote controller can send the econo command when the unit is in cool heat dry or auto operation 49
Outline the econo mode reduces the maximum operating current and power consumption by approx 30 during start up etc this mode is particularly convenient for energy saving oriented users it is also a major bonus for those whose breaker capacities do not allow the use of multiple electrical devices and air conditioners it is easily activated from the wireless remote controller by pushing the econo button 49
This function and powerful operation cannot be used at the same time the latest command has the priority 49
This function can only be set when the unit is running pressing the operation stop button causes the settings to be canceled 49
Upper limit of frequency 49
When the econo command is valid the input current is under reducing control refer to input current control on page 51 also the upper limit of frequency is restricted 49
When this function is on the maximum capacity is also down approx 20 49
Mold proof operation 50
A microcomputer in an indoor unit carries out a sampling every 20 msec and if it detects 10 cycles of the wave in one second in total corresponding to 20msec 10 200msec it judges human is in the room as the motion signal is on 51
Function and control 51
In case of fan mode the fan speed reduces by 50 rpm 51
Intelligent eye 51
Main functions si04 803 51
Processing 1 detection method by intelligent eye 51
The motions for example in cooling 51
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 51
This sensor detects human motion by receiving infrared rays and displays the pulse wave output 51
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 51
Details of the control when powerful button is pushed in each operation mode the fan speed setting temperature will be converted to the following states in a period of 20 minutes 53

Disconnect the compressor harness connector from the outdoor unit pcb to disengage the connector press the protrusion on the connector then follow the procedure below to measure resistance between power transistor and and the u v and w terminals of the compressor connector with a multi tester evaluate the measurement results for a pass fail judgment 146
If the fuse is blown out the outdoor unit fan may also be in trouble check the fan too if the voltage in step 2 is not applied it means the pcb is defective replace the pcb if the pulse in step 4 is not available it means the hall ic is defective replace the dc fan motor if there are both the voltage 2 and the pulse 4 replace the pcb 146
Make sure the voltage of 320 30v is being applied 1 stop the operation first and then the power off and disconnect the connector s70 2 make sure there is about dc 320 v between pins 4 and 7 3 with the system and the power still off reconnect the connector s70 4 make a turn of the fan motor with a hand and make sure the pulse 0 15 v appears twice at pins 1 and 4 146
Note check to make sure that the voltage between the terminal of power transistor and is approx 0 volt before checking power transistor 146
