* When the forced stop is triggered, indoor unit stops and Start/Stop operation by a
remote controller is restricted.
* When forced stop function is used with forming a remote controller group,
connect the same equipment to each indoor unit within the group.
• Selection method of functions
“Start/Stop” mode or “Emergency stop”, “Forced stop” mode can be selected with
function setting of indoor unit.
(2) External output terminals
• When picking up output signals for operating status, abnormal conditions or indoor unit
status.
Wiring methods and speci
fi
cations
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 492 ft. (150 m)
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
