Dip switch seting Operation Remarks
Test run
1. Setting operation mode
• The indoor unit automatically
starts to operate when the
test run of the outdoor unit
is set.
• You can perform the ON/OFF
operation from the remote
control switch or the DSW1
of the outdoor unit.
• Continuous operation during
2 hours is performed without
the Thermo-OFF condition.
• Make sure that the indoor
units start to operate in
accord with the test run of
the outdoor unit.
• If you start the test run from
the outdoor unit and you stop
the test run from the remote
control switch, the test run
function of the remote control
switch is cancelled. Howe-
ver, the test run function
of the outdoor unit is not
cancelled.
• If the more than one indoor
unit is connected with one
remote control switch, all the
units start the test run at the
same time. Therefore, turn
OFF the power source so
that the indoor units do not
perform the test run. If this is
the case, the TEST RUN in-
dication of the remote control
switch may icker. This is not
abnormal.
• The setting of DSW1 is not
required for the test run from
the remote control switch.
