Installation Instructions
Parts and Dimension of Wired Controller
Installation Requirements
- Prohibit installing the wired controller at wet places.
- Prohibit installing the wired controller at the places with direct sunshine.
- Prohibit installing the wired controller at the place near high temperature objects or water-splashing places.
Installation Methods
Fig. 23 is the simple installation process of wired controller; please pay attention to the following items:
- Before installation, please cut off the power for indoor unit;
- 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.
- Stick the soleplate of wired controller on the wall and then use screw M4×25 to fix soleplate and installation hole on wall together, attach the sponge 20×20×3 at the screw hole and then press it with fingers to make sure it’s attached firmly.
- 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.
- Block the four-core wire into the groove at the left side of wiring column; bundle the front panel of wired controller to its soleplate.
Note:
- 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.
- 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.
- The 4-core terminal connects the air conditioner, while the 2-core terminal connects the centralized controller. The connecting method for the 2-core connection wire is same as that of 4-core connection wire.
- No need to set the wire of wired controller into the clasp.
For matching with different models, the patch cord and the connection wire are provided in the packaging box of wired controller. As shown in fig. A.
- If the air conditioner has been installed with the patch cord (f ig . C ) used for connecting the wired controller.
Only use the connection wire (fig. B) in the packing box of wired controller. Connect the terminal ② to the terminal ④ of patch cord which has been installed on the air conditioner; insert terminal ① to needle stand CN2 of wired controller. If there’s protection terminal ③, pull out the protection terminal at first and then install it.
- If the air conditioner hasn’t been installed with the patch cord used for connecting the wired controller.
Use the connection wire and patch cord in the packing box of wired controller. Pull out the protection terminal of patch cord at first, connect the connection wire with the patch cord according to fig. D, and then insert the terminal ① of connection wire into the needle stand CN2 of wired controller and insert the terminal ⑤ of patch cord into the terminal of wired controller of air conditioner as well.
