1. Take down wire controller from the holder

2. Install the controller holder

According to the position of 2 screw holes on the holder, drill 2 holes on the wall, and strike the wood stopper to the holes respectively.

Then align the 2 screw holes of wired controller holder to the wood stopper, x the holder on the wall with wood screw.

3.Wiring instruction

Use shielded wire between indoor and wire controller. And be earthed on one side, or the unit will not work normally because of interference.

Note:

Try a wall as at as possible for installation. Don't use excessive force to tighten screws, otherwise, the holder will be

damaged.

Note:

Conrm the terminal connection rmly, and do not get in tough with shielded wire.

Don't touch the PC panel with your hands.

Installation Manual For Wire Controller

There are three methods to connection wire controller and the indoor units: A.One wired controller can control max. up to 16 sets of indoor units, and 3 pieces of polar wire must connect the wire controller and the master unit (the indoor unit connected with wire controller directly), the others connect with the master unit through 2 pieces of polar wire. B. One wire controller controls one indoor unit, and the indoor unit connects with the wire controller through 3 pieces of polar wire. C. Two wired controllers control one indoor unit. The wire controller connected with indoor unit is called master one, the other is called slave one. Master wire controller and indoor unit; master and slave wire controllers are all connected through 3 pieces of polar wire.

6. Communication wiring:

The wire controller is equipped with special communication wiring in the accessories. 3-core terminal (1-white 2-yellow 3-red) is connected with the terminal A, B, C of wire controller respectively.

The communication wiring is 5 meter long; if the actual length is more than it, please distribute wiring according to below table:

*One side of the shielded sheet of communication wire must be earthed.
