CONTROL SYSTEM 12.1.2 Compressor Frequency Control 12.1.2.1 Compressor frequency setting The Load calculation is done by each indoor unit controller, based on a PI control scheme which is based on the difference between SPT and RAT. ODU controller will decide the compressor frequency based on the total load from all the indoors. Compressor frequency will be limited within following ranges: Minimum Frequency (MinFreq) Maximum Frequency (MaxFreq) *...

CONTROL SYSTEM 12.9.1 Installation Test Installation test is to check any mistake in communication wiring or EEV wiring connections. Start Installation Test: RC setting: SPT=30, Cool Mode and press the button “-, +,-, +,-, +” continuously in 3 sec. Unit operation during Installation test: Unit will operate in cool mode (IFAN will stop), IDU will display “dd”.
TROUBLESHOOTING TROUBLESHOOTING 13.1 ELECTRICAL & CONTROL TROUBLESHOOTING 13.1.1 Precautions before Performing Inspection or Repair Be cautious during installation and maintenance. Do operation following the regulations to avoid electric shock and casualty or even death due to drop from high attitude. * Static maintenance is the maintenance during de-energization of the air conditioner.
