How to install
For a dual remote controller system, install the
remote controller as follows:
1. Set one of the remote controllers as the
main remote controller. (The default setting
is “Main Remote Controller.”)
2. Slide the DIPl switch 1 on the remote
control ler circuit board to the ON position
to set the other remote controller as the
sub remote controller.
■
Basic circuit diagram
• Use the remote controllers installed in two
different locations to operate the same
indoor unit.
• Use the remote controllers installed in two
different locations to centrally control multiple
indoor units.
* The main remote controller and sub
remote controller both can work in case of
connecting to any indoor unit.
Switching of temperature sensor
Both the remote controller and the indoor unit
have built-in temperature sensors, and the two
sensors cannot work at the same time.
The temperature sensor in the indoor unit is
the default sensor.
If to switch to the temperature sensor in the
remote controller, slide dial switch 4 on the
remote controller circuit board to the ON position.
Note 1:
On the main remote controller, you can
switch to the sensor in the remote controller. (If
the remote controller is a sub remote controller,
it is unable to switch.)
Note 2:
When using a separately sold remote
controller sensor, set the sensor inside the
remote controller to OFF.
Requirements
When using the remote controller for the first
time, the initial operation after power on will
last for a while. This is not a fault.
<Initial turn on time>
Let the remote controller run for
about 5 minutes.
<Turn on time after the second turn on>
Let the remote controller run for
about 1 minute.
The address setting of the multi-split air
conditioners cannot be completed just by
turning on the power (“SETTING” always
flashes). You must perform the operation on
the outdoor interface circuit board to complete
the address setting. The remote controller
cannot be operated when setting the address.
It takes at most 10 minutes to set the address.
Remote controller test run setup
1. Press the ON/OFF button.
Turn off the air conditioner.
2. Press the timer off button and the “
△
”
set button at the same time for at least 10
seconds. The LCD display area shows
“TEST” and becomes test mode.
3. The test run shall be performed in heating
or cooling mode.
• During test run, “TEST” is displayed on
the LCD display.
• When “TEST” is displayed, the
temperature cannot be adjusted.
• During test run, the machine will bear
a considerable load; therefore, it is
advisable not to carry out a test run
unless necessary.
Note 1:
After power up, the outdoor unit will not
work within about 3 minutes; otherwise
the operation will stop.
4. After exiting the test run mode, press
the timer off button again to ensure that
“TEST” on the LCD display disappears.(The
remote controller has a 60-minute timer off
function to prevent continuous test run.)
