Memory switchover: Under the “Off” state of the unit, press Mode and Ÿ at the same time for
5s to switch memory states between memory on and memory off. When this function is activated,
Memory will be displayed. If this function is not set, the unit will be under the “Off” state after power
failure and then power recovery.
Memory recovery: If this function has been set for the wired controller, the wired controller after
power failure will resume its original running state upon power recovery. Memory contents: On/
Off, Mode, set temperature, set fan speed and Lock function.

Fig.4.2
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 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 controller.
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.
CAUTION!
Please pay special attention to the followings during the connection to avoid the malfunction of
the air conditioning unit due to electromagnetic interference.
ķ .
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.
ĸ .
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.

5 Errors Display
If there is an error occurring during the operation of the system, the error code will be displayed
on the LCD, as show in Fig.5.1. If multi errors occur at the same time, their codes will be displayed
circularly.
Note: In event of any error, please turn off the unit and contact the professionally skilled
personnel.
