interference will affect the unit normal operation. Then confirm the terminals connected well and
not touch the shielded wire.

4. Cautions
Avoid switching on or off the unit frequently.
When you set one indoor at cooling mode (DRY) or heating mode, if the other indoors are in
different modes, this indoor will be at standby state.
Press TEMP. button to increase or reduce the set temperature, then the unit maybe stop, which is
not failure.
In cooling(or heating) mode, even indoor temp. is lower than (or higher than) the set temp., the unit
still is running in cooling (or heating) mode, which is not abnormal.
In DRY mode, fan speed will change automatically due to indoor temperature, which can not be
controlled by the fan speed button.
When wired controller is electrified for the 1
then LED and clock area will flash [88]→[8] →[88] for about 30 seconds. At this time, all buttons
are invalid.
If indoor requests fixed fan speed, you can not adjust the fan speed, and wired controller will
display FIX. If this model is equipped with AUTO RESTART function, when re-electrified, the unit
will display the original state before power is off.
Enter the mode of failure check
After entering the failure check mode, "18" in temp. area will display the unit number. "0" is the
actual connected indoor number (decimal), meanwhile, "88" in temp. area will display the latest
failure code (hex), and fan speed area will display "1"; press +/- button to check the former failure
code, and fan speed area will display "2".
Every time you press "CHECK" button, unit number will increase 1 untill it is 15; press again, it is
"0", then recycle. That is cycling as 0～15～0.
If within 5 seconds, no pressing "CHECK" button, it will quit the failure check mode automatically.
Cancel failure history: in normal state, press "CHECK" for 5 seconds continuously, you will cancel
the failure history.
