(*1): Do not set “STOP” or “Run Mode Shift” when using other central stations at the same time. When setting outdoor
unit capacity control, set one of the central station and do not set the others.
(*2): Setting is only possible for Stop or Run Mode Shift. And it is not possible to set multiple contact points.
(*3): When operating in “AUTO” mode, or when “Fixing Operation Mode” is enabled at “Optional Function Setting”.
(*4): Operation stops even if it is in Auto mode, or if the operation mode is xed in the optional function settings.
(*5): Outdoor unit capacity control can be set to multiple contact points. When there is a signal input in multiple contact
points, the priority for the execution of the controls is established according to the input number (Input 1 > Input 2 >
Input 3 > Input 4).
(*6): There are cases in which the outdoor unit may not support certain settings, or in which available settings may dif-
fer according to its capacity value. Please contact with your dealer or with the designated customer service centre for
detailed information.
(*7): It is possible to control via schedule without using demand control.

The contact can be switched.
Pulse width is 300 ms or more for pulse signal input.
• Output Terminal: Contact (voltage is applied) for signal Output DC12V
Recommended Relay: MY Relay manufactured by Omron Corporation
(Do not use a diode built-in type.)
• Input/Output connection: using accessory connector cord
Connection procedure:
