5.3. Connection of Remote Controller Cable
When connecting the remote controller cable to the indoor unit, do not
connect it to outdoor unit, power supply cable, or transmission cable
terminal blocks. It may cause a failure.
When switching the DIP switch (SW1), be sure to turn off the power
supply to the indoor unit. Otherwise, the PC board of the indoor unit may
be damaged.
•
There are 2 methods to connect the remote controller cable to the indoor
unit. One is the connection using connecting cable (shipped with the
indoor unit), and the other is the connection the remote controller cable is
connected to the exclusive terminal block of the indoor unit.
•
This is 3WIRE of remote control cables.
•
The factory default setting of the DIP switch (SW1) is "2WIRE"
Using this setting, however, will disable normal operations.
5.3.1. Check whether or not a DIP switch (SW1) is present.
Find the DIP switch (SW1), which switches between 2WIRE and
3WIRE on the indoor unit PC board.
