9.1.2 Setting in site

The whole machine has been completely installed and is initially energized.
Set with the special remote controller within 1 m from the infrared ray receiver on the
indoor unit in the following way: press numeric keys on the remote controller according
to the desired unit number, the remote controller LCD displays the corresponding
number, then press the "UNIT SET" key to send signals.
When the indoor unit receives the unit number setting signal sent by the special remote
controller, the buzzer beeps once indicating the indoor unit has received the unit number
setting signal. Set all unit numbers in turn, and confirm all unit numbers after setting
with the remote controller "READ" function in the following way: with the remote
controller aiming at the indoor unit signal receiver, press the "READ" key on the remote
controller, the indoor unit power indicator will flash. The flashing time is just the indoor
unit number. (e.g. for a unit number setting of 2, when pressing "READ" key, the power
indicator will flash twice.)
During unit number setting, if duplicate unit numbers are found, the indoor unit buzzer
will beep twice to indicate refusal of the unit number setting.
When setting the unit numbers, in order to avoid setting the same numbers, every two
units shall be set with an interval of 10 s so as to allow the indoor unit to automatically
identify the repeatedly number setting.
Please set the unit numbers in sequence and make records so as to avoid repeatedly
number setting.
If the indoor unit shows flashing of power, timer and operation indicators at the same
time, it indicates conflict of original addresses between indoor unit and outdoor unit and
the necessity to reset the unit number. Upon initially installation, whether the power,
indicator and operation indicators flash or not, the indoor unit number shall be set.
The code selecting function of the unit number setting remote controller may change the
emitting code. The up arrow means new emitting code while the down arrow indicates
original emitting code. Please select according to necessity.
