6.4.1 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
terminals 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 DC 12 to 24 V. Select a power supply capacity with an ample
surplus for the connected load.
Do not impress a voltage exceeding 24 V across pins 1-2, and 1-3.
*a: The allowable current is DC 5 mA to 10 mA. (Recommended: DC 5 mA)
Provide a load resistance such that the current becomes DC 10 mA or less.
Select very low current use contacts (usable at DC 12 V, DC 1 mA or less).
*b: The polarity is [+] for pin 1 and [-] for pin 2 and 3. Connect correctly.
