Fig1.4 Installation of Wired Controller
Above is a simple installation method of wired controller. Please pay attention to the following:
◆Before installation, disconnect power of the indoor unit. Do not operate when power is connected.
◆Pull out the 2-core twisted pair cable from the installation hole on the wall and lead it through the hole
on the back plate of wired controller.
◆Place the wired controller on wall and secure its back plate on wall with screw M4X25.
◆Connect the 2-core twisted pair cable to terminal H1 and terminal H2. Tighten up the screws.
◆Stick the cable in the slot that is left of the terminals and buckle the wired controller’s panel with its
back plate.
Note:
If caliber of the communication cord is too large, which causes difficulty in leading or sticking the cord
according to above point 2 and point 5, strip some of the sheath of the communication cable to meet the
installation requirement.
