(1) External input
• Indoor unit can be Operation/Stop, Emergency stop or Forced stop by using indoor unit
PCB CNA01 or CNA02.
• "Operation/Stop" mode, "Emergency stop" mode or "Forced stop" mode can be selected
with function setting of indoor unit.
• Indoor unit can be Forced thermostat off by using indoor unit PCB CNA03 or CNA04.
• A twisted pair cable (22 AWG) should be used. Maximum length of cable is 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.
Input select
Use either one of these types of terminal according to the application. (Both types of termi-
nals cannot be used simultaneously.)
● Apply voltage terminal ([CNA01], [CNA03])
When a power supply must be provided at the input device you want to connect, use the
Apply voltage terminal ([CNA01], [CNA03]).

*1 Make the power supply DC12 to 24V. Select a power supply capacity with an ample sur-
plus for the connected load.
Do not impress a voltage exceeding 24V across pins 1-2, and 1-3.
*a The allowable current is DC 5mA to 10mA. (Recommended: DC5mA)
Provide a load resistance such that the current becomes DC10mA or less.
Select very low current use contacts (usable at DC12V, DC1mA or less).
*b The polarity is [+] for pin 1 and [-] for pin 2 and 3. Connect correctly.
When connected to Apply voltage terminals of multiple indoor units with a connected unit,
be sure to make a branch outside the indoor unit using a pull box, etc. as shown on below
example.

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.

Operation behavior
● Input signal type
The input signal type can be selected.
It is switched by DIP switch on the indoor unit PCB.
