*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 remove them.
