T-RUN

: Test run (compressor and fan motor turn ON).

TEST/MV : Compresses time to 1/60th (accelerates 

operation by 60 times faster than normal).

Use the remote controller to operate the
unit in "TEST run" mode. To determine
whether the mode is currently in
"TEST run" mode, check the 4 indicator 
lamps on the unit. If all 4 are blinking,
the current mode is "TEST run."

 If there are no problems with the above, then check the outdoor unit.

1

The rated voltage must be present between inter-unit wirings 1 and 2.
Connect a 5 k ohm resistor between inter-unit wirings 2 and 3. When the 
voltage at both ends is measured, approximately 12 to 15V DC must 
be output and the multimeter pointer must bounce once every 8 
seconds.
Or instead of measuring the voltage, you can insert an LED jig and 
check that the LED flickers once every 8 seconds.

Apply the rated voltage between outdoor 
unit terminals L and N.

 If there are no problems with the above, then check the indoor unit.

1

The control panel LED (red) must illuminate.

Short-circuit the outdoor unit COM terminal 
to the T-RUN terminal.

2

The compressor, fan motor and 4-way valve must all turn on.
