1.Push SET , CL , and TEST 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. ALL is displayed.) In this time, the item code (DN) 10 is displayed.

2. Every pushing UNIT 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)

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 r1.

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.

10.After completion of setup, push TEST 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 CL button if the item code (DN) was not yet changed.
