Fig.4: Sketch for Installation of Wired Controller. Pay attention to the following items during installation of 
wired controller:
1. Cut off power supply of heavy-current wire embedded in mounting hole in the wall before installation. It 
is prohibited to perform the whole procedure with electricity.
2. Pull out 4-core twisted pair line in mounting hole and then make it through the rectangle hole at the back 
of controller’s soleplate.
3. Joint the controller’s soleplate on wall face and then x it in mounting hole with screws M4×25.
4. Insert the 4-core twisted pair line through rectangle hole into controller’s slot and buckle the front panel 
and soleplate of controller together.
5. At last, x the controller’s front panel and soleplate with screws ST2.2×6.5.
Caution:
During  connection  of  wirings,  pay  special  attention  to  the  following  items  to  avoid  interference  of 
electromagnetism to unit and even failure of it.
1. To ensure normal communication of the unit, signal line and wiring (communication) of wired controller 
should be separate from power cord and indoor/outdoor connection lines. The distance between them should be 
kept 20cm in min. 
2. If the unit is installed at the place where there is interference of electromagnetism, signal line and wiring 
(communication) of wired controller must be shielded by twisted pair lines.
