- The motions for example in cooling 54
- This sensor detects human motion by receiving infrared rays and displays the pulse wave output a micro computer 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 100msec it judges human is in the room as the motion signal is on 54
- When a micro computer doesn t have a signal from the sensor in 20 minutes it judges that no body is in the room and turns off the human detection led operating the unit in temperature sifted 2 c from the set temperature cooling 2 c higher dry 1 c higher and auto according to the operation mode at that time 1 in case of fan mode the fan speed reduces by 50 rpm 54

- When installing sky air simultaneous operation multi unit set to either twin or triple only when the factory setting is changed it is necessary to make a setting using a remote controller 4 for further details see the installation instruction 5 since drafts may result carefully select the installation location 6 when power returns units resume the settings made before the power outage 178
- After completing setting seal off the opening of the address switch and the main sub switch with the attached sealing pad 179
- Explanation 179
- If several wireless remote controller units are used together in the same room including the case where both group control and individual remote controller control are used together be sure to set the addresses for the receiver and wireless remote controller for group control see the attached installation manual for the indoor unit if using together with a wired remote controller you have to change the main sub setting or the receiver 179
- Setting the receiver 179
- Through the small opening on the back of the receiver set the wireless address switch ss2 on the printed circuit board according to the table below 179
- When using both a wired and a wireless remote controller for 1 indoor unit the wired controller should be set to main therefore set the main sub switch ss1 of the receiver to sub 179
- Wireless setting address and main sub setting 179
- 1 hold down the button and the button for at least 4 seconds to get the field set mode indicated in the display area in the figure at right 2 press the button and select a multiple setting a b each time the button is pressed the display switches between a and b 3 press the button and button to set the address 180
- Address can be set from 1 to 6 but set it to 1 3 and to same address as the receiver the receiver does not work with address 4 6 4 press the button to enter the setting 5 hold down the button for at least 1 second to quit the field set mode and return to the normal display 180
- Multiple settings a b 180
- Setting the address of wireless remote controller it is factory set to 1 180
- When the indoor is being operating by outside control central remote controller etc it sometimes does not respond to on off and temperature setting commands from this remote controller check what setting the customer wants and make the multiple setting as shown below 180
- After setting 181
- Fan speed off when thermostat is off 181
- Precautions set the unit no of the receiver and the wireless remote controller to be equal if the setting differs the signal from the remote controller cannot be transmitted 1 do not use any settings not listed in the table 2 for group control with a wireless remote controller initial settings for all the indoor units of the group are equal for group control refer to the installation manual attached to the indoor unit for group control 181
- Setting table 181
- Stick the unit no label at decoration panel air discharge outlet as well as on the back of the wireless remote controller 181
- Ultra long life filter sign setting 181
- When a ultra long life filter is installed the filter sign timer setting must be changed 181
