External input and output PCB.
4. 2. External input and output
4. 2. 1. External input
• Indoor unit functions such as Operation/Stop or Forced stop can be
done by using indoor unit terminals.
• “Operation/Stop” mode or “Forced stop” mode can be selected with
function setting of indoor unit.
• A twisted pair cable (22 AWG) should be used. Maximum length of
cable is 492 ft. (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.
●
Dry contact terminal
When a power supply is unnecessary at the input device you want to connect, use the Dry
contact terminal.

• 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
