This multiple remote controller system controls 1 to 8 indoor
units with 2 simplified remote controllers.
Set-up procedure
1. One of the 2 simplified remote controllers should be set as
main controller.
2. Set the address switch on the other simplified remote
controller P.C.B. from OFF to ON. (Fig. 3-40)
The simplified remote controller can now be used as a
sub-remote controller.

Remote Controller Test Run Setting
1. Push the tip of a ball-point pen, etc. into the hole marked
“TEST” for more than 4 seconds and press the (ON/
OFF) button.
“TEST” will appear on the crystal display during test
run.
During test run, temperature cannot be adjusted. This
button should be used only for test run.
2. Perform test run in any operation mode of “Heat,” “Cool”
or “Fan.”
Note: The outdoor unit does not operate for 3 minutes after
stopping operation or turning on the unit.
3. After finishing the test run, push the tip of a ball-point pen,
etc. into the hole marked “TEST” again until “TEST”
disappears from the crystal display.
(The 60-minute off timer function is provided for this re-
mote controller in order to avoid continuous test run.)
