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 150 m (492 ft.).
• 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.
