Connecting to External Equipment

• Non-voltage contact "a"
• Keep the external I/O wiring lengths of 20 meters 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
