Fig.4.2 shows the installation steps of the wired controller, but there are some issues that need your attention.
(1) Prior to the installation, please rstly 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 controller.
(3) Stick the soleplate of the wire controller to the wall over the installation hole and then x it with screws M4X25.
(4) Insert the four-core twisted pair line into the slot of the wired controller and then buckle the front panel and the soleplate of the wired
controller together.
(5) Finally, x the front panel and the soleplate of the wired controller tightly by screws ST2.9X6.
CAUTION!
Please pay special attention to the followings during the connection to avoid the malfunction of the air conditioning unit due to
electromagnetic interference.
(1) Separate the signal and communication lines of the wired controller from the power cord and connection lines between the indoor and
outdoor unit, with a minimum interval of 20cm, otherwise the communication of the unit will probably work abnormally.
(2) If the air conditioning unit is installed where is vulnerable to electromagnetic interference,then the signal and communication lines of
the wired controller must be the shielding twisted pair lines.
