12.Trouble suspension

When indoor fan motor is out of order or compressor-lock occurs, the compressor, indoor fan motor, outdoor fan
motor, and louver are all stopped and the operation LED(red) turns off and the timer LED(yellow) turns on or off
as follows.

13.Test mode

13-1 TEST 1(For control circuit operation checking)

Make terminals 1 and 2 of connector CN4 short-
circuited and supply the power.
Hereby the timer's period becomes shortened.
In this test mode, the control times are shortened
as follows.

The operation LED flicker's period:
in Test run :                                       not shortened

13-2 TEST 2 (For output of each operation checking)

Keep pushing both the buttons, "AUX." and :
"TEST RUN" and supply the power, the system
will go to the test 2 mode.
In this mode, the output of operation is switched
by pushing the button "TEST RUN" on the unit
or the button "0/I" on the remote controller.
Use the button "AUX."  to back to step 1.
Normal outputs are shown in Table H-5, H-6.
