Applicable models

This installation sheet applies to AppStat controllers
for fan coil units. The model numbers for these
models end with "0001". Additional information for
the controllers can be found in the document

Installation, Operation and Application Guide for the
AppStat

which is available on the KMC partners web

site.

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.

Illustration 2—Typical motion sensing coverage area

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 1

.

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.
