If the power supply wiring is mistakenly connected
to a terminal board other than the power supply
terminal board, the devices connected to this
controller or this controller will malfunction.
Connecting to External Equipment
• Non-voltage contact "a"
• Keep the external I/O wiring lengths of 66 ft. (20 m) or less. If a longer length is needed, use a Communication Adaptor or relay.
• A voltage of DC5 V (approx. 10 mA) is applied to the contact to detect the input signal.
• Do not apply an external voltage to the input terminal.
• The contact allowable voltage and current for the output signal terminal are max. DC30 V and 0.5 A respectively.

• Minimum pulse width: 30 msec
or more, or 100 msec or more
(selectable by setting)
• Minimum pulse interval: 1 sec
Setting and Test Operation
Turn on all of the indoor units and the outdoor units.
Turn on the Communication Adaptor (only when
connected), and make the necessary settings.
(See "Installation Instructions" supplied with the
Communication Adaptor.)
