Planning for motion sensing
For models with a motion sensor mount the KMD-
5290 LANController 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 KMD-5290 LANController
For the most accurate performance, install the KMD-
5290 LANController 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 KMD-5290 LANController 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.
For models with motion sensing, see the topic,
Planning for motion sensing.
Rough-in preparation
Complete rough-in wiring at each location before
mounting an KMD-5290 LANController. This
includes the following steps.
Install the supplied mounting base directly to a
wall, a vertical electrical box, or a box with a wall
plate kit.
Routing the connecting cable or cables from the
KMD-5290 LANController to the equipment it is
controlling.
If required, install an appropriate wall plate kit.
Block leaks and airflow from conduits with
plumber’s putty or similar material.
If replacing an existing thermostat, label existing
wires for reference when removing the existing
thermostat.

Installing the KMD-5290 LANController
To install the controller on a mounting base, do the
following:
1. Turn the Allen screw in the base of the sensor
clockwise until it clears the case.
Turn clockwise to remove
from base.
2. Swing the KMD-5290 LANController away from
the mounting base to remove it.
3. Route wiring for the KMD-5290 LANController
through the mounting base.
4. Position the base with the embossed UP toward
the ceiling and fasten it directly to a vertical 2x4
inch electrical box. For horizontal boxes or 4x4
applications, use a wall plate kit. See Installation
accessories on page 5 for part numbers.
5. Connect the wires for the KMD-5290
LANController to the terminals in the mounting
base.
6. Place the top of the sensor over the top of the
mounting base and swing it down over the Allen
screw bracket. Be careful not to pinch any wiring.
7. Turn the Allen screw counterclockwise until it
backs out of the mounting base and engages the
case.
Turn counterclockwise
until the screw engages
the base.

Caution
To prevent mounting screw
heads from touching the circuit
board in the controller, use only
the mounting screws supplied by
KMC Controls. Using screws
other than the type supplied may
damage the KMD-5290
LANController.
Connecting inputs
The inputs for the KMD-5290 LANController are
configured for specific functions and do not require
set up in the field. Not all inputs are required for
every model or application.

Remote space temperature sensor (optional)
Connect a 10kΩ, TypeII thermistor temperature
sensor to the remote space temperature (RS) input
and ground (GND) terminals. The input includes
the internal pull-up resistor. An STE-6011W10
sensor is suitable for this application. Follow the
instructions supplied with the sensor for installation.
When a remote space temperature input is
connected to the KMD-5290 LANController, the
remote temperature is used instead of the internal
temperature sensor.
Fan status switch (optional)
Connect a Normally Closed Fan Status switch to the
Discharge Air Temperature (DAT) input and
ground (GND) terminals. The input includes the
internal pull-up resistor. A CSE-1102 differential
pressure switch is suitable for this application.
Follow the instructions supplied with the switch for
installation.
Outdoor air temperature sensor
Connect a 10kΩ, Type III thermistor temperature
probe to the outdoor air temperature (OAT) input.
The input includes the internal pull-up resistor. An
STE-1451 sensor is suitable for this application.
Follow the instructions supplied with the sensor for
installation.
Discharge air temperature
Connect a 10kΩ, Type III thermistor temperature
probe to the discharge air temperature (DAT) input.
The input includes the internal pull-up resistor. An
STE-1405 sensor is suitable for this application.
Follow the instructions supplied with the sensor for
installation.
Connecting outputs
The KMD-5290 LANController outputs are model
dependent and are configured for specific
applications.
No field programming or set up is required or
possible.
Depending on model and application, the KMD-
5290 LANController outputs are designed for
either 24 voltAC or 0-10 voltDC loads.
The outputs may represent analog or digital
signals.
Caution
Improperly connecting loads or
equipment to output terminals
may damage the equipment.
Connect only as shown in the
following diagrams or application
drawings.

Connecting power
The KMD-5290 LANController requires an external,
24 volt, AC power source. Use the following
guidelines when choosing and wiring transformers.
Use only a Class-2 transformer of the appropriate
size to supply power.
KMC Controls recommends powering the KMD-
5290 LANController from a dedicated controls
transformer.
Connect the transformer’s neutral lead to the
COM terminal.
Connect the AC phase lead to the 24VAC
terminal.
Power is applied to the controller when the
transformer is powered.
See Installation accessories on page 5 for a list of
transformers available from KMC Controls, Inc.
