Pattern 1 ON ON No response to the external contact signal control.
(Factory default setting)
Pattern 2 ON OFF
Used for emergency cases such fire.
 Responds when there is an input signal on DI-1
 Operation:
Turns off all the indoor units when there is an ON signal input,
and disables the use of all the remote controllers. During an
emergency stop, the DMS will ignore any request from the
higher level controllers. The schedules and the peak power
control will not operate as well. The indoor units are restored to
the previous operation status when the input signal changes to
OFF. (The DI-2 is not used for pattern 2.)
Pattern 3 OFF ON
 Responds when there is an input signal on DI-1 and DI-2.
 Operation:
Changes the on/off status of all the indoor units depending
on the ON/OFF status of the DI-1 input. Enables/disables the
remote controllers depending on the ON/OFF status of the DI-2
input. (ON: enable/ OFF: disable)
The schedules and the peak power control will run regardless of
pattern 3.

 Responds when there is a pulse input on DI-1,2.
 Operation:
Turns on all the indoor units when there is a pulse input on DI-1.
Turns off all the indoor units when there is a pulse input on DI-2.
Turns off all the indoor units when there is a pulse input on DI-1,
DI-2. (The pulse width is valid only for 0.5~1.0 sec.)
