R.C. address S002 CN031
1 1 off off short (for a system without link)
12 2 off on open (for a system with link)
23 3 on off open (for a system with link)
● Setting of indoor control PCB
No setting necessary.
Each indoor unit address (UNIT No: R.C. - No.) is decided after Auto. address operation.
Manual setting for indoor unit address can also be performed with the remote controller.
● Check items before the test run
1 Turn on all power supply switches more than 5 hours before in order to charge the crank-case heater.
2 Fully open the outdoor service valve after making the leak inspection of field connected tubing,
vacuuming, and gas charging.
