7-10. Test Run Switch
7-10-1. How to use the test run setting (X, T Types)
The test run switch is located in the operating control unit.
Regarding the test run, refer to section 11. Test Run.
In case of 4-way air discharge type, test run operation is not possible without the ceiling panel installation.
To protect the air conditioner from overloading, the outdoor unit will not start running for 3 minutes after
power is applied or the air conditioner is turned off and then back on.
When the air conditioner fails to start the test run, 1 or more of the 3 alarm indicator lamps on the indoor
unit will flash (See next section).

When the DIP switch is set to “TEST – ON,” temperature control from the wireless remote controller is disabled.
Do not use this setting at any time other than for the test run. Doing so will place an excessive load on the system.
To avoid placing an excessive load on the equipment, use this function only when conducting the test run.
NOTE
Set DIP switch [DS] No. 1 on the wireless receiver
unit PCB from OFF to the ON position. (1)
Press the ON/OFF operation button on the
wireless remote controller. (2)
Make a test run using the air conditioner in
COOL or HEAT mode. (3)
During the test run, each of the 3 indicator lamps
on the indoor unit flash. (4)
During the test run, the air conditioner runs
continuously and the thermostat does not control
the system. (5)
After the test run, be sure to reset DIP switch No. 1
back to the OFF position and check that no indicator
lamps are blinking.
(This receiver includes a 60-minute automatic OFF
timer function in order to prevent continuous test run.) (6)
