5.5. Setting addresses (Fig. 5-5)

(Be sure to operate with the main power turned OFF.)

• There are two types of rotary switch setting available: setting addresses 1 to 9

and over 10, and setting branch numbers.

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”.

How to set branch numbers SW14 (Series R2 only)

Match the indoor unit’s refrigerant pipe with the BC controller’s end connec-

tion 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 the Data Book.

5.6. Sensing room temperature with the built-in sen-

sor 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.

6. Test run

Do not carry out this test on the control wiring (low voltage circuit) termi-

nals.

Warning:

Do not use the air conditioner if the insulation resistance is less than 1.0 M

6.1. Before test run

After completing installation and the wiring and piping of the indoor and

outdoor units, check for refrigerant leakage, looseness in the power sup-

ply or control wiring, wrong polarity, and no disconnection of one phase

in the supply.

Use a 500-volt megohmmeter to check that the resistance between the

power supply terminals and ground is at least 1.0 M

Using wired remote controller (Fig. 6-1)

Turn on the power at least 12 hours before the test run.

Press the [TEST] button twice. “TEST RUN” liquid crystal display

Press the [Mode selection] button and switch to the cooling (or heating) mode.

Make sure that cold (or warm) wind is blown out.

Press the [Fan speed] button. Make sure that the wind speed is switched.

Press the [Air direction button] or [Louver button].

Check operation of the vane or louver.

Check operation of the outdoor unit fan.

Release test run by pressing the [ON/OFF] button. Stop

The telephone number of the repair shop, sales office, etc., to contact if an error

occurs can be registered in the remote controller. The telephone number will be

displayed when an error occurs. For registration procedures, refer to the opera-

tion manual for the indoor unit.

Note:

• If an error code is displayed on the remote controller or if the air condition-

er does not operate properly, refer to the outdoor unit installation manual

or other technical materials.

• The OFF timer is set for the test run to automatically stop after 2 hours.

• During the test run, the time remaining is shown in the time display.

• During the test run, the temperature of the indoor unit refrigerant pipes is

shown in the room temperature display of the remote controller.

• When the VANE or LOUVER button is pressed, the message “NOT AVAILA-

BLE” may appear on the remote controller display depending on the indoor

unit model, but this is not a malfunction.

MA Remote controller

• Connect the “1” and “2” on indoor unit TB15 to a MA remote controller. (Non-

polarized 2-wire)

• DC 9 to 13 V between 1 and 2 (MA remote controller)

M-NET Remote controller

• Connect the “M1” and “M2” on indoor unit TB5 to a M-NET remote controller.

(Nonpolarized 2-wire)

• DC 24 to 30 V between M1 and M2 (M-NET remote controller)

Wireless remote controller(When installing wireless signal receiver)

• Connect the wire of wireless signal receiver (9-pole cable) to CN90 of indoor con-

troller board.

• When more than two units are run under group control using wireless remote

controller, connect TB15 each with the same number.

• To change Pair No. setting, refer to installation manual attached to wireless re-

mote controller. (In the default setting of indoor unit and wireless remote control-

ler, Pair No. is 0.)
