11. REPLACEMENT OF SERVICE INDOOR P.C. BOARD

[Requirement when replacing the service indoor P.C. board assembly]

In the non-volatile memory (Hereinafter said EEPROM, IC10) installed on the indoor P.C. board before replacement, the type and capacity code exclusive to the corresponding model have been stored at shipment from the factory and the important setup data such as system/indoor/group address set in (AUTO/MANUAL) mode or setting of high ceiling selection have been stored at installation time. Replace the service indoor P.C. board assembly according to the following procedure.

After replacement, check the indoor unit address and also the cycle by a test run.

<REPLACEMENT PROCEDURE>

CASE 1

Before replacement, power of the indoor unit can be turned on and the setup data can be readout from the wired remote controller.

Read EEPROM data *1 (ref. P89)

ò

Replace service P.C. board & power ON *2 (ref. P89)

ò

Write the read data to EEPROM *3 (ref. P90)

ò

Power reset (All indoor units in the group when group operation)

CASE 2

Before replacement the setup data can not be readout from the wired remote controller.

Replace service P.C. board & power ON *2 (ref. P89)

ò

Write the data such as high ceiling setup to EEPROM (According to the customers’ information) *3

ò

Power reset (All indoor units in the group when group operation)

1 Readout of the setup data from EEPROM

(Data in EEPROM contents, which have been changed at the local site, are read out together with data in

EEPROM set at shipment from the factory.)

1. Push

SET

, , and buttons of the remote controller at the same time for 4 seconds or more.

1

(Corresponded with No. in Remote controller)

When group operation, the master indoor unit address is displayed at the first time. In this time, the item code (DN)

10

is displayed. The fan of the selected indoor unit operates and the flap starts swinging if any.

2. Every pushing button, the indoor unit address in the group are displayed successively.

2

Specify the indoor unit No. to be replaced.

3. Using the set temperature / buttons, the item code (DN) can be moved up and down one by one.

3

4. First change the item code (DN) from

10

to

01

. (Setting of filter sign lighting time) Make a note of the set data displayed in this time.

5. Next change the item code (DN) using the set temperature / buttons. Also make a note of the set data.

6. Repeat item 5. and make a note of the important set data as shown in the later table (Ex.).

•

01

to

9F

are provided in the item code (DN). On the way of operation, DN No. may come out.

7. After finishing making a note, push button to return the status to usual stop status.

2 Replacement of service P.C. board

1. Replace the P.C. board with a service P.C. board.

In this time, setting of jumper line (cut) or setting of (short-circuit) connecting connectors on the former P.C.

board should be reflected on the service P.C. board.

2. According to the system configuration, turn on power of the indoor unit with any method in the following items.

a) In case of single (individual) operation

Turn on the power supply.

1) Wait for completion of automatic address setup mode (Required time: Approx. 5 minutes) and then proceed to r

3.

(Line address = 1, Indoor address = 1, Group address = 0 (Individual) are automatically set.)

2) Push

SET

, , and buttons of the remote controller at the same time for 4 seconds or more

(

1

operation), interrupt the automatic address setup mode, and then proceed to

(Unit No.

ALL

is displayed.) r

3.

b) In case of group operation

Turn on power of the indoor unit of which P.C. board has been replaced with the service P.C. board with any method in the following items.

1) Turn on power of the replaced indoor unit only.

(However, the remote controller is also connected. Otherwise r

3 operation cannot be performed.)

Same as 1) and 2) in item a).

2) Turn on power of the multiple indoor units including replaced indoor unit.

•

Only 1 system for twin, triple, double twin

•

For all units in the group

Wait for completion of automatic address setup mode (Required time: Approx. 5 minutes) and then proceed to r

3.

* The master unit of a group may change by setup of automatic address. The line address/indoor address of the replaced indoor unit are automatically set to the vacant addresses except addresses belonging to other indoor units which have not been replaced. It is recommended to make a note that the refrigerant line which includes the corresponding indoor unit and that the corresponding indoor unit is master or sub in the group control.

3 Writing of the setup contents to EEPROM

(The contents of EEPROM installed on the service P.C. board have been set up at shipment from the factory.)

1. Push

SET

, , and buttons of the remote controller at the same time for 4 seconds or more.

1

(Corresponded with No. in Remote controller )

In group operation control, the master indoor unit No. is displayed at the first time. (If the automatic address setup mode is interrupted in item 2. - a) - 2) in the previous page, the unit No. the item code (DN)

ALL

is displayed.) In this time,

10

is displayed. The fan of the selected indoor unit operates and the flap starts swinging if any.

2. Every pushing button, the indoor unit numbers in the group control are displayed successively.

2

Specify the indoor unit No. of which P.C. board has been replaced with a service P.C. board.

(When the unit No.

ALL

is displayed, this operation cannot be performed.)

3. Using the set temperature / buttons, the item code (DN) can be moved up and down one by one.

3

4. First set a type and capacity of the indoor unit.

(Setting the type and capacity writes the data at shipment from the factory in EEPROM.)

1) Set the item code (DN) to

10

. (As it is)

2) Using the timer time / buttons, set up a type.

4

(For example, 4-way air discharge cassette type is 0001) Refer to the attached table.

3) Push

SET

button. (OK when the display goes on.)

5

4) Using the set temperature / buttons, set

11

to the item code (DN).

5) Using the timer time / buttons, set the capacity.

(For example, 0012 for class 80) Refer to the attached table.

6) Push

SET

button. (OK when the display goes on.)

7) Push button to return the status to usual stop status.

6

(Approx. 1 minute is required to start handling of the remote controller.)

5. Next write the contents which have been set up at the local site such as the address setup in EEPROM.

Repeat the above procedure 1. and 2.

6. Using the set temperature / buttons, set

01

to the item code (DN).

(Setup of lighting time of filter sign)

7. The contents of the displayed setup data in this time should be agreed with the contents in the previous memorandum in r

1.

1) If data disagree, change the displayed setup data to that in the previous memorandum by the timer time

/ buttons, and then push

SET

button. (OK when the display goes on.)

2) There is nothing to do when data agrees.

8. Using the set temperature / buttons, change the item code (DN).

As same as the above, check the contents of the setup data and then change them to data contents in the previous memorandum.

9. Then repeat the procedure 7. and 8.

<REMOTE CONTROLLER>

*

10. After completion of setup, push button to return the status to the usual stop status.

6

(Approx. 1 minute is required to start handling of the remote controller.)

01

to

9F

are provided in the item code (DN).

On the way of operation, DN No. may come out.

When data has been changed by mistake and

SET button has been pushed, the data can be returned to the data before change by pushing button if the item code (DN) was not yet changed.
