«Important»
Do not install the controller in a place where the difference
between the remote controller surface temperature and the
actual room temperature will be great.
If the temperature difference is too high, room temperature
may not be adequately controlled.
To reduce the risk of shorting, current leakage, electric
shock, malfunctions, smoke, or fire, do not install the con-
troller in a place exposed to water or in a condensing envi-
ronment.
(2) Installation space
Leave a space around the remote controller as shown in the figure at right,
regardless of whether the controller is installed in the switch box or directly
on the wall. Removing the remote controller will not be easy with insufficient
space.
Also, leave an operating space in front of the remote controller.
4. Installation / Wiring work
(1) Installation work
Controller can be installed either in the switch box or directly on the wall.
Perform the installation properly according to the method.
Drill a hole in the wall.
■ Installation using a switch box
• Drill a hole in the wall, and install the switch box on the wall.
• Connect the switch box to the conduit tube.
■ Direct wall installation
• Drill a hole in the wall, and thread the cable through it.
Seal the cable access hole with putty.
■ Installation using a switch box
• Seal the remote controller cable access hole at the connection of
switch box and conduit tube with putty.
To reduce the risk of electric shock, malfunctions, or fire, seal
the gap between the cables and cable access holes with putty.
Prepare the bottom case of the remote controller.
Connect the remote controller cable to the terminal block on the bottom case.
Peel off 6 mm of the remote controller cable sheath as shown in the figure below, and thread the cable from behind the bot-
tom case. Thread the cable to the front of the bottom case so that the peeled part of the cable cannot be seen behind the
bottom case. Connect the remote controller cable to the terminal block on the bottom case.
Thread the sheath part
of the cable to the front.
