   • ERV wired remote controller can be opened in the sliding way . (Hold the front cover and then lift it up to disassemble the front cover .)
     

2. Fix the mounting plate of the ERV wired remote controller on the wall with 2 screws.
   

3. Connect the F3, F4 of PCB terminal in ERV to F3, F4 of ERV wired remote controller terminal.
   

4. Arrange the connected communication wires correctly depending on the installation condition.

   • When the ERV wired remote controller is embedded on the wall: Make the wire go through the hole in the center of the mounting plate .
   • When the ERV wired remote controller is installed on the wall: Remove the thin parts on the front and mounting plate to make the wires go through as seen in the picture

5. Reassemble the ERV wired remote controller.

Caution

• When installing the ERV wired remote controller by using a wire longer than 10 m, you must install the communication wire of the ERV wired remote controller and the AC power cable separately . (Electrical interference can cause your ERV wired remote controller to malfunction .)
• When installing your ERV wired remote controller on the wall, consider the size of the wire hole, and select a wire with a proper thickness .
• Wire that is connectable to ERV wired remote controller PCB .
  • If you install the ERV wired remote controller by embedding it on the wall, install it according to U-terminal cable specification .
  • If you install the ERV wired remote controller by using two pieces of PVC wire, remove the 30 cm of the sheath of the cable and install it only with the two pieces of wires . (Recommended specification: AWG21)
• The followings are the specs of the compressed U terminal connectable to your ERV wired remote controller PCB
