NOTE: The communicating thermostat is able to search and
identify the indoor and outdoor units when power is applied to
the system. Refer to the communicating thermostat's instal-
lation instructions for more information.
Connect low voltage communication wires (1, 2) to low volt-
age pigtail provided.

NOTE: A removable plug connector is provided with the
control board to make thermostat wire connections. Remove
the plug, connect the wires to the plug, and then replace. It
is strongly recommended that you do not connect more than
two wires into a single terminal in the field because there is a
risk of the wires becoming loose, which may result in commu-
nication error. Refer to Troubleshooting Tables for error codes.
To wire the system components, it is strongly recommended
to use the same type and same gauge for the wires prepared
in the field. (For best results, use 18 AWG.) However, commu-
nications reliability may be improved by using a high quality,
shielded, twisted pair cable for the data transmission lines.
Finally, be sure to confirm that the wires do not come off each
terminal after all connections are finished.

Typical wiring will consist of two wires between the indoor unit
and outdoor unit, and four wires between the indoor unit and
thermostat. The figure that follows shows the required wires:
data lines, 1 and 2; "R" (24 VAC hot) and "C" (24 VAC common).
Never connect the power wiring to communication terminal.

ATTENTION INSTALLER -
IMPORTANT NOTICE!
Please read carefully before installing this unit.
• Low voltage terminal C from indoor unit must connect
to low voltage terminal C on thermostat and low voltage
terminal R from indoor unit must connect to low voltage
terminal R on thermostat. Verify wires are not reversed.
(Note: The order of the terminals of the indoor unit and
your thermostat may be different system wiring.)
• Do not attach any wires to the R & C Terminals on the
Outdoor Unit, as they are not needed for inverter unit.
• Data line terminal #1 from outdoor unit must connect
to terminal #1 on indoor unit and thermostat and data
line terminal #2 from outdoor unit must connect to
terminal #2 on indoor unit and thermostat. Verify wires
are not reversed.
