CAUTION:
- Check to ensure that the wiring is correct. Incorrect wiring may
cause malfunction of the centralized ON/OFF controller.
- Turn OFF the power supply of the air conditioner and the
centralized ON/OFF controller when performing the wiring work.
If the wiring work is performed while the power supply of the
centralized ON/OFF controller is being supplied, it may cause
malfunction of the centralized ON/OFF controller.
- DO NOT run all the transmission cable for the centralized
ON/OFF controller along the power line and other transmission
cables, or malfunction may occur due to the noise, etc. If the
transmission cable for the centralized ON/OFF controller is
required to be run along the power line and other transmission
cables, separate the cable more than 30 cm away from other
cables, or run the cable through a metal tube and earth the tube.
- In case of applying high voltage to the TB2, the fuse on the PCB
is blown out.
In such a case, firstly correct the wiring to TB1, and then set No.2
pin ON.
