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.
ū 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.
ū 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.
ū 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.
ū When the wire is extended from the upper side of the ERV
wired remote controller and covered with a protection tube:
Remove the contact point of the protection tube about
1 cm or more so that the front cover can be assembled
without a problem.
5. Reassemble the ERV wired remote controller.

02 INSTALLATION
• 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.
ū If you install the ERV wired remote controller by embedding it on the wall, install it
according to U-terminal cable specication.
ū 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 specication: AWG21)
• The followings are the specs of the compressed U terminal connectable to your ERV wired
remote controller PCB.
