8. WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER

8-1 HOW TO CONNECT WIRINGS 

Connect the piping only after finishing the refrigerant piping work.

Make sure all power supply is shut down to the unit first.

As shown in the Fig. 16, loosen the two screws in the control box lid, remove it, and do the wiring work.

Once all wiring is done, attach the control box lid and secure it with the screws.
If you are using “8-4 DEFAULT SETTINGS,” however, finish that and then attach the control box lid and 
secure it with the screws.

8-2 THE GAS PIPING THERMISTOR

Connect to (X5A) on A1P.

Bundle the gas piping thermistor lead wire and the branch wiring (transmission) using the included 
clamping material.

Tension is not added to the gas pipe thermistor lead wire coming out of the unit.

• Power supply wiring

• Ground wire

Connect the wiring to R (L) and S (N) on the power supply terminal block (X1M). Also, connect the ground 
wire to the ground terminal. Take the wiring and the ground wire into the unit through the wiring pass-through 
hole, and firmly secure them together using the included clamp (1).

• Indoor unit inter-unit wiring

Connect the wires to 1, 2, and 3 on the power supply terminal block (X1M). Take the wires into the unit 
through the wiring pass-through hole, and firmly secure them using the included clamp (1).

• Transmission wiring

Connect the wires to F1 and F2 on the transmission terminal block (X2M). Take them into the unit through 
the wiring pass-through hole, and firmly secure the gas piping thermister lead wire and the transmission 
wiring using the included clamp (1).

[ CAUTIONS ] 

Do not under any circumstances connect the power supply wiring to the transmission terminal block (F1, 
F2), as this may cause damage to the entire system.

CAUTION

When clamping wiring, use the included clamping material to prevent outside presure being exerted on the 
wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not 
cause the control box lid to stick up, then close the cover firmly.

When attaching the control box lid, make sure you do not pinch any wires.

After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If any do get in, they 
could cause short circuits in the control box.)

Outside the machine, separate the weak wiring (gas piping thermistor lead wire, transmission wiring) and 
strong wiring (power supply wiring, inter-unit wiring, ground wire, and other power wiring) at least 50mm so 
that they do not pass through the same place together. Proximity may cause electrical interference, mal-
functions, and breakage.
