*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 5~10 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.
When connected to 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.

Connected unit
• No voltage terminal ([CN17])
When a power supply is unnecessary at the input device you want to connect, use the no
voltage terminal ([CN17]).

*c Select very low current use contacts (usable at DC 12 V, DC 1 mA or less).
*d The wiring is different from voltage terminals. Be suffi ciently careful when wiring.
When connected to no voltage terminals of multiple indoor units with a connected unit,
insulate each indoor unit with relay, etc. as shown on below example.
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-sw on the indoor
unit PCB.

* 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" mode, "Forced stop" mode can be selected with
function setting of indoor unit.
