4-2-3-2 Settings for when the GB-24A is connected to an existing LAN
When connecting the GB-24A to an existing LAN, consult with the network administrator who is responsible for
the LAN before setting the IP address, subnet mask, or gateway address.
4-2-4 External Input Setting
In the External Input Setting menu, set the GB-24A external input function. By using external input functions, it
is possible to stop and run multiple air conditioners connected to the GB-24A via the separately sold external
I/O adapter for GB-24A (Model: PAC-YG10HA) using level signals and pulse signals.
(1) Select [Not in use] when not using the external input function.
(2) Selecting [Emergency stop (Level signal)] makes it possible to stop multiple units by using a level signal.
While this stop operation is being performed, operations such as running or stopping units are prohibited on
the GB-24A unit or remote control.
(3) Selecting [ON/OFF (Level signal)] makes it possible to run or stop multiple units using a level signal. In this
mode, all air conditioner units connected to the GB-24A will be run or stopped and run/stop operations will
be prohibited on the GB-24A unit or remote control.
