Planning for motion sensing
For models with a motion sensor mount the AppStat
on a wall that will have an unobstructed view of the
typical traffic in the coverage area. When choosing a
location, do not install the sensor in the following
areas.
Behind curtains or other obstructions
In locations that will expose it to sunlight or heat
sources
Near a heating or cooling inlet or outlet.

Installation Guide
The effective detection range is approximately 10
meters or 33 feet. Factors that may reduce the range
include:
False detections may be triggered by:
Mounting the AppStat
For the most accurate performance, install the
AppStat on an inside wall where it can sense the
average room temperature. Avoid locations with
direct sunlight, heat sources, windows, air vents,
and air circulation or obstructions such as curtains,
furniture, etc.
The AppStat must not be:

The difference between the surface temperature
of the object and the background temperature of
the room is too small.
Object movement in a direct line toward the
sensor.
Very slow or very fast object movement.
Obstructions as shown in the illustration
motion sensing coverage area on page 1
The temperature inside the detection range
suddenly changes because of the entry of cold or
warm air from an air-conditioning or heating
unit.
The sensor being directly exposed to sunlight, an
incandescent light, or other source of far-infrared
rays.
Small animal movement.
Mounted on an exterior wall.
Mounted on or near an object with large a
thermal mass such as a concrete block wall.
Blocked from normal air circulation by
obstructions.
Exposed to heat sources such as lights,
computers, copiers, or coffee makers, or to direct
sunlight at any time of the day.
Exposed to drafts from windows, diffusers, or
returns.
