● Dry contact terminal ([CNA02], [CNA04])
When a power supply is unnecessary at the input device you want to connect, use the Dry
contact terminal ([CNA02], [CNA04]).

connected unit
*c Select very low current use contacts (usable at DC12V, DC1mA or less).
*d The wiring is different from Apply voltage terminals. Be suffi ciently careful when wiring.
When connected to Dry contact terminals of multiple indoor units with a connected unit,
insulate each indoor unit with relay, etc. as shown on below example.

* When the forced stop is triggered, indoor unit stops and Operation/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
"Operation/Stop" mode or "Emergency stop" mode, "Forced stop" mode can be selected
with function setting of indoor unit.
● Forced thermostat off function
["Edge" input only]

(2) External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25m.
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• Output voltage: Hi DC12V±2V, Lo 0V.
• Permissible current: 50mA
