Installing the ERV wired remote controller

Installation procedure

1. Push up the bottom part of the ERV wired remote controller’s front cover to disassemble the front cover from the mounting plate.
   • 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
  

❋ Maximum distance for connecting communication and power cable: 100 m(328 .08 ft)

• Screws on the PCB terminal must be tightened with less than 6N-cm tightening torque . If the tightening torque is greater, it may damage the screw thread

Tracking ERVs from the ERV wired remote controller

1. Tracking of your ERV wired remote controller automatically starts when you turn on the power after installation.
2. If you want to perform tracking again after installation, press the Fan speed and buttons at the same time for more than five seconds.
   • The system is reset, and tracking starts again .
3. During the tracking, the total number of currently searched products is displayed.
4. It may take about 5 minutes at initial installation or when you re-set the master setting.

Caution 

• If you want to perform system reset of ERV wired remote controller, press the Fan speed and  buttons at the same time for more than five seconds

When a upper controller is not connected

Individual control means that you are using one ERV wired remote controller to control one ERV

Caution

• Regardless of the setting of group address (RMC address), only the ERV connected to COM2 communication wire is individually controlled

When a upper controller is connected

ERV interface module (MIM-N10)

Caution

• Regardless of the setting of group address (RMC address), only the ERV connected to COM2 communication wire is individually controlled

Group control with your ERV wired remote controller

Group control means that you are using one ERV wired remote controller to control two or more ERVs at the same time

1. Using one ERV wired remote controller to control three ERVs.
   
2. Using one ERV wired remote controller to control ERVs connected to other ERV repeaters in a group.
   

Caution
