Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnec-
tion, heating or fire result.

Notes:
*1 Put the transmission cable earth via the outdoor unit's earth terminal
to the ground.
*2 If the remote controller cable exceeds 10 m, use a 1.25 mm
the exceeded portion, and add that exceeded portion to within 200 m.
*3 The BC controller is required only for simultaneous cooling and heating
series R2.

8.3. Connecting electrical connections

(Be sure to prevent terminal screws from loosening.)
1. Remove 2 screws which secures the terminal bed box cover using a screw-
driver. (1)

C Screw (2 places)
2. As shown at 2, wire the power supply, transmission cable and remote control-
ler. There is no need to remove the terminal bed box.

E Transmission cable
(To terminal bed for M-NET remote controller, indoor unit and BC controller)
F To single-phase power supply
G Terminal bed for power supply
H To terminal bed for outdoor transmission cable
(Use shielding earth cable
• Fix power source wiring to terminal bed box by using buffer bushing for tensile force.
(PG connection or the like.) Connect transmission wiring to transmission terminal
bed through the knockout hole of terminal bed box using ordinary bushing.

3. After wiring is complete, make sure again that there is no slack on the connections,
and attach the cover onto the terminal bed box in the reverse order of removal.
Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnec-
tion, heating or fire may result.

8.4. Setting addresses

(Be sure to operate with the main power turned OFF.)
[Fig. 8.4.1] / [Fig. 8.4.2] (P.5)
<Address Switch>
<Address board>
• There are two types of rotary switch setting available: setting addresses 1 to 9
and over 10, and setting branch numbers.
1 How to set addresses
Example: If Address is "3", remain SW12 (for over 10) at "0", and match
SW11(for 1 to 9) with "3".
2 How to set branch numbers SW14 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end con-
nection number. Remain other than series R2 at "0".
• The rotary switches are all set to "0" when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set
them referring to technical data.
Note:
Please set the switch SW5 according to the power supply voltage.

8.5. Sensing room temperature with the
built-in sensor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote control-
ler, set SW1-1 on the control board to "ON". The setting of SW1-7 and SW1-8 as
necessary also makes it possible to adjust the air flow at a time when the heating
thermometer is OFF.
