OPTION/EXTENSIONS OF COMMUNICATION 
WIRING — To extend control wiring or to make terminal
connections, use the PQE connection wire supplied in the
accessory kit and follow the steps below. 

1.

Cut the connector on the outdoor unit side as shown in
Fig. 25 below.

2.

Strip a suitable length of the insulation layer as shown in
Fig. 26 below. 

3.

Use a suitable screwdriver to fix the communication wire
on the outdoor unit communication terminal as shown in
Fig. 27 below.

If communication wires are used to connect indoor units,

find the corresponding port and plug it in as shown in Fig. 28.

If it is not possible to buy communication wires from

Carrier, connect the indoor unit side of the communication
wires using the connector provided with the accessories as
shown in Fig. 29 below. See Fig. 30 and 31 for typical
communication wiring of the heat pump and the heat recovery
systems.

CAUTION

Failure to follow these procedures may result in personal
injury or damage to equipment.
NEVER CONNECT the main power source to the control
or communication terminal block.
USE AN APPROPRIATE SCREWDRIVER for 
tightening the terminal screws. Do not over tighten the 
terminal screws.

IMPORTANT: Wiring for communication shall be 2
inches or more apart from power source wiring to avoid
electric noise. Do not insert control/communication and
power source wire in the same conduit.

Pay attention to the polarity of the communication 
wire.
