Installation Location We recommend that this system controller be installed properly by quali ed installation technicians in accordance with the Installation Instructions provided with the system controller.

Do not install this system controller where there are fumes or ammable gases, or in an extremely humid space such as a greenhouse. Do not install the system controller where excessively high heat- generating objects are placed.

Electrical Requirements 1. All wiring must conform to the local electrical codes. Consult your dealer or a

quali ed electrician for details. 2. Wiring must be done by a quali ed electrician.

CAUTION To warm up the system, the power mains must be turned on at least ve (5) hours before operation. Leave the power mains ON unless you will not be using this appliance for an extended period.

Safety Instructions Read this booklet carefully before using this system controller. If you still have any dif culties or problems, consult your dealer for help. The air conditioner is designed to give you comfortable room conditions. Use this only for its intended purpose as described in the Operating Instructions.

Never touch the unit with wet hands. Never use or store gasoline or other ammable vapor or liquid near the air conditioner it is very dangerous. The air conditioner has no ventilator for intaking fresh air from outdoors. You must open doors or windows frequently when you use gas or oil heating appliances in the same room, which consume a lot of oxygen from the air. Otherwise there is a risk of suffocation in an extreme case.

CAUTION Do not turn the air conditioner on and off from the power mains switch. Use the ON/OFF operation button. Do not stick anything into the air outlet of the outdoor unit. This is dangerous because the fan is rotating at high speed. Do not let children play with the air conditioner. Do not cool or heat the room too much if babies or invalids are present.

3. How to install the system controller

CAUTION Do not twist the control wiring together with the power wiring or run it through the same metal conduit, because this may cause a malfunction. Install the system controller away from sources of electrical noise. Install a noise lter or take other appropriate action if electrical noise affects the power supply circuit of the unit.

Do not supply power to the unit or try to operate it until the tubing and wiring to the outdoor unit is completed.

6. How to perform zone registration To operate the system controller properly, zone registration is required after nishing the test run (and after setting all indoor unit addresses) using one of the following methods.

(a) Zone registration using the remote controller Refer to page 14

(b) Zone registration using the system controller Refer to page 15

(c) Automatic zone registration using the system controller Refer to page 16

For methods (a) and (b), you should make a zone registration table manually before performing the registration as shown on the page 13.

For method (c), zone registration is executed automatically, proceeding from small indoor unit address and small central addresses to larger numbers in numerical order. For example:

Central address 1 2 3 4 5 6

ZONE-group 1-1 1-2 1-3 1-4 1-5 1-6

Indoor unit address 1-1 1-2 2-1 2-2 2-3 3-1

NOTE 1. An indoor unit address is assigned to each indoor unit during automatic address operation. Each indoor unit address combines an R.C. address and indoor unit number as follows:

1 1 : Indoor unit address (UNIT No.) Indoor unit No. Refrigerant circuit No. (R.C. address)

This address is displayed on remote controller for UNIT No. when the UNIT button is pressed.

2. The central address represents the zone and group number. These addressed are assigned in ascending numerical order.

(a) Zone registration using the remote controller (Determination of central address)

In this case, after con rming which indoor unit is connected to the remote controller and that the air conditioner in the OFF state, you set the central addresses one at a time.

If the system has no remote controller, connect a remote controller to the system temporarily. Then follow this procedure.

NOTE

The indoor unit address must already have been set before performing zone registration. If necessary, refer to the Installation Instructions supplied with the outdoor unit.

(1) Press the and buttons at the same time of the remote controller for more than 4 seconds.

(2) Do not press button.

(3) Once in this mode, the UNIT No., CODE No., No. of SET DATA and indications will ash on the display as shown Fig. 8.

NOTE

In case of group control ALL instead of UNIT No. will ash on the display. Select the main indoor unit address by pressing the button once.

(4) Set CODE No. to 03 using the and ( ) buttons.

NOTE

The CODE No. 03 must be selected to perform zone registration using the remote controller.

(5) Set the Central address which you want to assign to the indoor unit address using the and ( ) buttons according to the zone registration table.

(6) Press the button. The CODE No. and Central address changes from ashing to ON state. If you make mistake, then press the button and reset the central address.

(7) Press the button to nish zone registration.

Fig. 8

For example, in this case Indoor unit address: 1-8 Central address : 17 (ZONE 2, GROUP 1)

(b) Zone registration using the system controller In this case, you set all Central addresses by

system controller at once manually.

(1) Press the and buttons at the same time for more than 4 seconds.

and CODE No. C1 will ash.

(2) After con rming that CODE No. C1 is displayed, press the button. Once in this mode, a change takes place as Fig. 10.

(3) Select the zone and group No. which you want to set with and (GROUP) buttons.

If already set, press the buttons.

(4) Set the unit No. (Indoor unit address) with and buttons, according to the zone registration table.

R.C. No. ..................... button

Indoor unit No. ........... button

(5) Press the button. GROUP No. turns ON and UNIT No. (Indoor unit

address) changes from ashing to ON state. UNIT No. is registered to selected ZONE No. and GROUP No.

If you make mistake, then press the button and reselect the ZONE, GROUP and UNIT No.

(6) Register the other UNIT No. in the same way by following the steps (3) to (5).

(7) Finally, complete the registration by pressing the button.

If no data is registered no number is displayed.

Selected group No. if no data is registered.

If data is registered the unit No. is displayed.

For example, in the case at left Zone 3, group No. 7 Unit No. (indoor unit address) 2-8

Unit No. 2-8 is registered to zone 3-group 7.
