The unit is designed to work as part of a fully communicat-
ing HVAC system, utilizing a Daikin approved communicat-
ing thermostat, Communicating indoor unit, and up to four
wires. Route control wires through the low voltage port and
terminate in accordance with the wiring diagram provided
inside the top plate.

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 instruction manual 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. This plug
may be removed, wire connections made to the plug, and
replaced. Do not connect multiple wires into a single terminal.
Typical 18 AWG wire may be used to wire the system compo-
nents. However, communications reliability may be improved
by using a high quality, shielded, twisted pair cable for the
data transmission lines.

Low voltage wiring consists of two wires between the indoor
unit and heat pump and four wires between the indoor unit
and thermostat. The required wires are data lines 1 and 2,
"R" (24 VAC hot) and "C" (24 VAC common).
Never connect the power wiring to communication terminal.
