Rear plate b): Flush mounting

Fig. 3-57

1. Decide how the system controller will be mounted: in the normal manner or fl ush with the wall.

a) To mount the system controller in the normal manner, remove the mounting plate.

Then reattach the 4 screws to the electrical component box.

b) To mount the system controller fl ush with the wall, make an opening in the wall measuring 128 mm x 128 mm. The opening must be at least 85 mm deep as measured from the outside surface of the wall.

2. Remove the rear plate and connect the electrical wiring.

1) Remove the 4 screws located on both sides of the rear plate.

2) Either the hole in the top of the electrical component box or the hole in the rear plate may be used to feed the electrical wiring.

3) If the hole on top is used, the rear plate should be turned upside down.

3. Secure the system controller in place.

a) If the system controller is being mounted in the normal manner, fi rst attach the rear plate to the wall using the screws and Rawl plugs provided. Next, place the body of the system controller over the rear plate and secure it in place using four screws.

b) If the system controller is being mounted fl ush with the wall, fi t it through the mounting plate on the wall and secure it in place using the screws and Rawl plugs provided.

3

NOTE To mount the system controller on a wall made of cinder block, brick, concrete, or a similar material, drill 4.8 mm diameter holes in the wall and insert Rawl plugs to anchor the mounting screws.

How to Perform Zone Registration

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

(a) Zone registration using the remote controller (RCS-TM80BG)

Refer to page 3-80

(b) Zone registration using the system controller (SHA-KC64AGB)

Refer to page 3-81

(c) Automatic zone registration using the system controller (SHA-KC64AGB)

Refer to page 3-81

For methods (a) and (b), you should make a zone registration table manually before performing the registration. Use the form on page 3-79 for this.

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

Central address

ZONE-group

Indoor unit address

1

1-1

1-1

2

1-2

3

1-3

2-1

4

1-4

2-2

5

1-5

2-3

6

1-6

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 addresses are assigned in ascending numerical order.
