CAUTION
To avoid placing an
excessive load on the
equipment, use this
function only when
conducting the test run.
(3) Make a test run using the air conditioner in
COOL or HEAT mode.
(4) During the test run, the “OPER.,” “TIMER,”
and “STDBY” LED all blink.
To protect the air conditioner from overloading, the outdoor unit will not start running for approximately 3 minutes
after power is applied or the air conditioner is turned off and then back on.
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.
(5) After the test run, press the ON/OFF operation button on the wireless remote controller. Then, set the
TEST RUN switch back to the OFF position to cancel the test run mode.
(This receiver includes a 60-minute automatic OFF timer function in order to prevent continuous test run.)
