Inverter principle 28
Main control parameters 28
Main function 28
The compressor is frequency controlled during normal operation the target frequency is set by the following 2 parameters coming from the operating indoor unit the load condition of the operating indoor unit the difference between the room temperature and the set temperature 28
The following drawing shows a schematic view of the inverter principle 28
The target frequency is adapted by additional parameters in the following cases frequency restrictions initial settings forced cooling heating operation 28
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 28

Flap control 32
Alternative repetition of vertical and horizontal swing motions enables uniform air conditioning of the entire room this function is effective for starting the air conditioner 33
Although the liquid crystal display of the five step directions of the air flow is common for the modes of cooling dry heating as illustrated above in fact the range of the swing angle is slightly different in every operation mode the position a user set will be selected among the five positions calculated through the preliminary and evenly divided into four partitions which were taken from the upper and lower flap angle s range limits of each mode when auto swing is chosen the flap swings in the swing range which meets the operation mode selected 33
Details of the action 33
Fan mode is available for the models of cooling only 33
It can be commanded for j type by means of a user setting to select either any one desired position among the five step directions of air flow adjusted on a remote controller or auto swing 33

Night set mode 39
One hour after the off timer is set the outdoor unit sets the upper limit of the operation frequency at the value close to the rated frequency to reduce the outdoor operating noise 39
Required fan speed fan speed changes the rotation speed every time when a thermostat switches over on and off when the thermostat becomes off fan continues to operate maximum 10 minutes with low speed so as to prevent dew condensation on the inside of the indoor unit and then stops 39
Sibe04 101 general functions 39
The frequency command for every zone is stated below please note that an operation will not carry out in the commanded frequency sometimes in case a protection control like a freeze protection etc will be actuated 39
The night set mode is automatically activated when the off timer is set the set temperature changes as time goes by the operation frequency is decreased and the operating noise is diminished during sleep 39

Disconnect the compressor harness connector from the outdoor unit pcb 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 130
Note check to make sure that the voltage between the terminal of power transistor and is approx 0 volt before checking power transistor 130
Note the charge section is applied with high voltage therefore exercise caution during measurement to prevent electric shock 130

Since capacitor and are connected to power transistor and capacitor voltage can be measured at the power transistor and terminals on this p c board powertransistor is terminal dc 1 or dc 2 and powertransistor is terminal dc 1 or dc 2 131
Take measurements at the power transistor and terminals in the same way as described in section 1 set the multi tester to dc and voltage range before measurement 131

Conduct the followings to check the electronic expansion valve ev 1 check to see if the ev connector is correctly inserted in the pcb compare the ev unit and the connector number 2 turn the power off and back on again and check to see if all the evs generate latching sound 3 if any of the evs does not generate latching noise in the above step 2 disconnect that connector and check the conductivity using a tester check the conductivity between pins 1 3 and 6 and between pins 2 4 and 5 if there is no conductivity between the pins the ev coil is faulty 133
Discharge pressure check 133
Electronic expansion valve check 133
If no ev generates latching sound in the above step 2 the outdoor unit pcb is faulty 5 if the conductivity is confirmed in the above step 2 mount a good coil which generated latching sound in the ev unit that did not generate latching sound and check to see if that ev generates latching sound if latching sound is generated the outdoor unit pcb is faulty if latching sound is not generated the ev unit is faulty 133
Note please note that the latching sound varies depending on the valve type 133
