and a message will be displayed for the device on
the My Home menu option.
• Move device closer to the S40 thermostat or
add an
Lennox Wireless Extender
between the
sensor and thermostat.
• For wall placement, install room sensor at a minium
height of 5 feet (1.52 meters) on an interior wall.
See
for illustration
example.
• Use the provided wall template when mounting
sensor to the wall.
• For sensor desktop/table placement use the
provided stand.
•
For effective temperature sensing, mount the
sensor in a location enabling it to sense the general
room environment. The sensor must NOT be:
»
Blocked from normal air circulation by ob-
structions (e.g., behind curtains or cubicle
walls).
»
Exposed to artificial heat sources (e.g., lights,
computers, copiers, or coffee makers) or to
sunlight (at any time of the day).
»
Exposed to direct sunlight.
»
Exposed to drafts from windows, doorways,
diffusers, or returns.
»
Exposed to air flow through the conduit (e.g.,
from leaks in plenum ducts) or other holes
into the wall cavity.
»
Mounted on an exterior wall.
»
Mounted on or near a large thermal mass
(e.g., a concrete block wall).
NOTE:
The above factors primarily affect tempera
-
ture sensing, but some also affect accurate
humidity and occupancy sensing as well.
»
If the device is out of range of your S40 ther-
mostat a blue light will turn on.
•
For effective occupancy detection, determine a
location that will maximize the area of detection in
a room.
»
The smart room sensor occupancy detec-
tion function has a 100 degree horizontal
span and a 32 degree vertical span. Improper
placement may limit the area of occupancy
detection for the sensor.
»
Large rooms may require more than one sen-
sor to ensure occupancy detection. Please
see
"Figure 9. Occupancy Sensor Detection

smart room sensor.
