The effective detection range is approximately 10 meters or 33 feet. Factors
that may reduce the range include:
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 Typical motion sensing coverage
area on page 17 .
False detections may be triggered by:
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.
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:
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.
Exposed to air flow through connecting conduits or empty spaces behind
walls.
