4 Installation and Dismantlement
4.1 Connection of the Signal Line of the Wired Remote Controller
Open the cover of the electric control box of the indoor unit.
Let the single line of the wired remote controller through the rubber ring.
Connect the signal line of the wired remote controller to the 4-pin socket of the indoor unit
PCB.
Tighten the signal wire with ties.
The communication distance between the main board and the wired remote controller can
be up to 20 meters ( the standard distance is 8 meters)

Fig.15 shows the installation steps of the wired remote controller, but there are some issues that need your attention.
(1). Prior to the installation, please firstly cut off the power supply of the wire buried in the
installation hole, that is, no operation is allowed with electricity during the whole installation.
(2). Pull out the four-core twisted pair line from the installation holes and then let it go through
the rectangular hole behind the soleplate of the wired remote controller.
(3). Stick the soleplate of wired controller on the wall and then use screw M4×25 to fix
soleplate and installation hole on wall together, attach the sponge 20×20×2 at the screw hole
and then press it with fingers to make sure it’s attached firmly.
(4). Insert the four-core twisted pair line into the slot of the wired remote controller and then
buckle the front panel and the soleplate of the wired remote controller together.
(5).
ST2.9X6.
Note：CN1 is 485 communication interface and it used
for connecting the 4-core communication wire.
These two needle stands(CN2、CN3) are used for
connecting the smart zone controller. There is no
sequence for these two needle stands. You can
connect one or two needle stand(s) basing on the
requirement.

Fig.16 shows the schematic diagram of control system connection. NPGA/19 can connect the smart zone
controller (integrated control system). “n” indicates the number of communication node address
(programmable wired controller NPGA/19). The complete system is composed of the smart zone controller,
wired controller NPGA/19 and communication cable. The wired controller NPGA/19 can support 16
Terminal A and terminal B of the smart zone controller are respectively connected to the corresponding
communication needle stand terminal of the #1wired controller by the communication cable; the other
needle stand of #1 wired controller is connected to the #2 wired controller through the telecommunication
cable and so forth until connect to the #n wired controller. Except the last wired controller in the control
system (only use CN2 or CN3, and the other one will not be connected), there’s no the sequence and the
importance for the wired controller. The series number in the figure is only for the sake of clarity.
Fig.17 shows schematic diagram of DIP switch. There is a 2-bit DIP switch on the main board of wired
controller NPGA/19. As for the last #n wired controller in the control system, the 1-bit and the 2-bit of the DIP
switch should be manually pulled to position “on” and position “off” respectively. The DIP switches of other
wired controllers should be kept at the initial ex-factory status (1-bit and 2-bit are set at position “off”).

CAUTION!
Please pay special attention to the followings during the connection to avoid the malfunction of
the air conditioning unit due to electromagnetic interference.

If the air conditioning unit is installed where is vulnerable to electromagnetic interference,
then the signal and communication lines of the wired remote controller must be the shielding
twisted pair lines.
