*1.Single-dotted lines indicate wiring
not supplied with the unit.
*2.Dot-dash lines indicate the control
box boundaries.
*3.Refer to the Data book for connecting
input/output signal connectors.
*4.Daisy-chain terminals (TB3) on the
outdoor units in the same refrigerant
system together.
*5.Faston terminals have a locking
function.Make sure the terminals
are securely locked in place after
insertion.Press the tab on the
terminals to removed them.
