- Function of thermistor 1 3 control specification 2 30
- Main functions 0 30
- Part 4 function and control 30
- Additional control parameters 31
- Drawing of inverter the following drawing shows a schematic view of the inverter principle 31
- Forced cooling operation 31
- Frequency principle 31
- Frequency restrictions 31
- Initial settings 31
- 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 31
- 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 31
- Main functions 31
- Note see the list of functions for the functions applicable to different models 31
- The difference between the room temperature and the set temperature 31
- The load condition of the operating indoor unit 31
- The target frequency is adapted by additional parameters in the following cases 31
- 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 32
- Energy saving heating and cooling once the set temperature is reached the energy saving operation enables to maintain the room temperature at low power 32
- Even during extreme cold weather the high capacity is achieved it is maintained even when the outside temperature is 2 c 32
- For more information refer to forced operation mode on page 32
- Forced cooling operation 32
- Frequency limits the following table shows the functions that define the minimum and maximum frequency 32
- Inverter features the inverter provides the following features 32
- Quick heating and quick cooling the compressor rotational speed is increased when starting the heating or cooling this enables a quick set temperature 32
- The regulating capacity can be changed according to the changes in the outside temperature and cooling heating load 32
- Auto swing the following table explains the auto swing process for heating cooling dry and fan 33
- The louvres made of elastic synthetic resin provide a wide range of airflow that guarantees a comfortable air distribution 33
- Wide angle louvers and auto swing 33
- Wide angle louvres 33
- Fan speed control for indoor units 34
- 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 35
- Programme dry function 35
- 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 35

- Note unless specified otherwise an indoor dry operation command must be regarded as cooling operation 43
- Outline there are two modes the mode selected in user s place normal air conditioning mode and forced operation mode for installation and providing service 43
- Frequency control 44
- For limiting lower limit frequency management is carried out only when the frequency rises 45
- Frequency initial setting outline when starting the compressor or when conditions are varied due to the change of the room the frequency must be initialized according to the total of a maximum d value of the indoor unit and the q value of the indoor unit q value indoor unit output determined from indoor unit volume air flow rate and other factors 45
- Frequency management when other controls are functioning 45
- I control if the operating frequency is not change more than a certain fixed time adjust the frequency up and down according to the d value obtaining the fixed d value when the d value is small lower the frequency when the d value is large increase the frequency 45
- Indoor frequency command d signal the difference between a room temperature and the temperature set by the remote controller will be taken as the d signal and is used for frequency command 45
- Limit of frequency variation width when the difference between input current and input current drooping value is less than 1 a the frequency increase width must be limited 45
- P control calculate d value in each sampling time 20 seconds and adjust the frequency according to its difference from the frequency previously calculated 45
- Pi control determine frequency up down by d signal 45
- Th off thermostat off 45
- Upper and lower limit of frequency by pi control the frequency upper and lower limits are set depending on indoor unit when low noise commands come from the indoor unit or when outdoor unit low noise or quiet commands come from indoor unit the upper limit frequency must be lowered than the usual setting 45
