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 DC12 to 24V. Select a power supply capacity with an ample
surplus 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.

● 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]).

*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.

NOTE :
When connected to multiple indoor units directly, it will cause breakdown.
Operation behavior
● Input signal type
The input signal type can be selected.
It is switched by DIP switch on the indoor unit PCB.
DIP switch [Set 2 SW2]
OFF (Factory setting)
● When function setting is "Operation/Stop" mode.
