(2) External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25m.
• 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

Controller PCB
• Remove the existing connector and replace it with the remote sensor connector (ensure
that the correct connector is used).
• The original connector should be insulated to ensure that it does not come into contact
with other electrical circuitry.
• Use conduit hole when external output cable is used.
CAUTION
To protect the cable insulation after opening a knockout hole, remove any burrs from
the edge of the hole.
Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
• Function Number “30”:
Set the Setting Number to “00”. (Default)
• Function Number “31”:
Set the Setting Number to “02”.
