7-2. P.C. BOARD MODIFICATION FOR INDIVIDUAL OPERATION

A maximum of 4 indoor units with wireless remote controllers can be used in a room.

In this case, to operate each indoor unit individually by each remote controller, P.C. boards of remote controller must be

modified according to the number of the indoor unit.

7-1. TIMER SHORT MODE

For service, set time can be shortened by short circuit of JPG and JPS the electronic control P.C. board.

The time will be shortened as follows. (Refer to 8-6.)

Set time : 1-minute ➔ 1-second

Set time : 3-minute ➔ 3-second

It takes 3 minutes for the compressor to start operation. However, the starting time is shortened by short

circuit of JPG and JPS.

How to modify the remote controller P.C. board

Remove batteries before modification.

The board has a print as shown below :

The P.C. board has the print “J1” and “J2”. Solder “J1” and “J2” according to the number of indoor unit as shown in Table 1.

After modification, press the RESET button.

NOTE : For modification, take out the

batteries and press the

OPERATE/STOP(ON/OFF)

button twice or 3 times at first.

After finish modification, put

back the batteries then press

the RESET button.
