3. Fix the back cover to the remote control as before.
Attentions
• Batteries can be used approximately for one year
under normal conditions.
• Always replace an identical type of two batteries at
the same time.
• Do not use manganese dry batteries since they may
cause a malfunction.
• Do not use rechargeable (Ni-Cd) batteries, because
such batteries may differ from standard dry cell
batteries in shapes, dimensions, or performance.

Control Box Assembly Location
The Control Box assembly may be located on any stable
moisture-free surface adjacent to fan coil or air handler.
It may be mounted in any orientation except with the
housing cover inverted, However, the following caution and
constraints must be observed when selecting the mounting
location.
1. The Control Box must not be located more than
2 meters from the location for mounting of the return
air sensor. Please ensure that return air sensor cable
is sufficiently long.
2. The Control Box must be located such as it is accessible
for future unscheduled inspection and that it does
not hinder inspection and removal of return air filters
or servicing of the fan coil or air handler.
3. Location of the Control Box must be over 14-meter
length of the cable assembly. That is sufficient to reach
and attach to the wall mounted receiver.
Attachment/Mounting Control Box
The Control Box attached to the mounting surface by
installing a screw through each of 4 holes in the Control
Box mounting flanges. The Control Box must not be
mounted in the inverted position such as overhead ceiling.
Mounting the Temperature Sensor
The return air sensor cable is factory installed inside the
Control Box and is connected to main PCB. Remove the
cover of Control Box, insert the sensor end through the
wiring bushing. Pull the sensor cable until the maximum
cable is outside of the Control Box.

Locating the Freeze Sensor
Locating the Temperature Sensor
Locate the return air sensor directly in the air returning to
the fan coil or air handler. It should be located so as not to
interfere with inspection or removal of return air filters or
servicing and repair fan coil or air handler.
Locate the freeze sensor
Locate the freeze sensor close to either U bend tube.

Cable Routing
- Connect either terminal to connector P10 at the
printed circuit board and the other to Display unit
(wall mouth).
- The cable should be installed and routed in the area
that not exposed to excessively hot temperature,
moisture, sharp edges and moving surface.
Install the wireless remote control and wired control as
follows:
Locate and attach the wireless remote control and
wired control as follows:
