• If replacing an existing room controller, label wires before
removal of controller.
• Electronic controls are static sensitive devices. Discharge
yourself correctly before manipulating and installing room
controller.
• A short circuit or wrong wiring may permanently damage
controller or equipment.
• BrightStat controllers are designed for use as operating
controls only and are not safety devices. Tampering with the
devices or unintended application of the devices will result in
a void of warranty.
• This device must be installed to provide a separation
distance of at least 8" (20cm) from all persons and must not
be collocated or operating in conjunction with any other

OVERVIEW
BrightStat
The BrightStat controller is a cost-effective solution for
upgrading air conditioner or heat pump thermostats.
The application allows existing wiring between the
wall-mount unit and the room controller to be re-
used, reducing overall costs and installation time. The
BrightStat can also add features like CO
2
and fresh air
monitoring to the existing functions of a wall-mount unit.
The BrightStat room controller can be configured to
handle a broad variety of applications covering all the
standard implementations necessary for HVAC systems.

8403-083 With Humidity Sensor VT8650U5000B
8403-084 Temperature Only VT8600U5000B
In addition to controlling heating, cooling and air
quality, depending on the model and accessories,
the BrightStat can handle wireless networking and
switches, Passive Infrared (PIR) occupancy detection
using either onboard or remote sensors, and can have
custom programs implemented to fulfill specific user
requirements. The applications described here cover
all these features in combination with the BrightStat’s
advanced scheduling and occupancy controls to provide
the functionality for any required HVAC implementation.

In all Occupancy Modes
If room relative humidity is higher than the user-defined
dehumidification setpoint, both Dehumidification
(DO12) and Fan (BO4) outputs are energized to reach
the RH% setpoint and the room controller.
NOTE: A relay is installed in the unit which will
disable dehumidification on a call for cooling or
heating.
See page 41 of Advanced Programming & User
Interface Setup Guide (manual 2100-681) for
occupied and unoccupied settings adjustments.
Wiring

instructions.
Sequence of Operation
Occupied Mode
Setpoints revert to those defined by occupied cooling
and heating.
Stand-by Mode (only available when PIR motion
detector sensor is used)
Setpoints revert to those defined by stand-by cooling
and heating.
Unoccupied Mode
Setpoints revert to those defined by unoccupied heating
and cooling.

POWER OUTAGE CLOCK RESET
In the event of a power outage, BrightStat Room
Controllers will retain the correct time as long as
the duration of the power outage is not prolonged.
Depending on the duration of the power outage,
the room controller's internal clock may need to be
updated or reset completely. The following table gives
an indication of the expected clock performance after a
power outage.

Expected Clock Performance After Power Outage
Outage Duration Room Controller Behavior
0-24 Hours Clock functions are normal.
24-36 Hours Clock accuracy not guaranteed,
time may need to be adjusted.
36-72 Hours
Clock no longer increments and
must be adjusted when power
is restored.
72+ Hours
Clock functions are fully reset and
must be re-initialized as per new
installation.

PASSIVE INFRARED SENSOR
Initially, the room controller is in Stand-by mode and
Stand-by setpoints are used. When the Passive Infra-
Red (PIR) sensor detects motion, the Occupancy
status switches to Occupied and the Stand-By Time
timer is reset. The Occupied setpoints are used for this
operation. If no motion is detected in the room for the
entire Stand-By Time duration (adjustable parameter),
the room switches to Stand-by mode and Stand-by
setpoints are used. While in Stand-by mode, if no
motion is detected for the entire Unoccupied Time
period (adjustable parameter), the room switches to
Unoccupied mode and uses its Unoccupied setpoints.

While in Stand-By or Unoccupied mode, any motion
switches the room back to Occupied mode.
The PIR sensor is located near the bottom of the front
of the BrightStat controller. Make sure there are no
obstructions in front of the sensor.
PIR ranges measure 20' (6 meters) at 140° and 13'
(4.5 meters) minimum between 15° to 30° laterally.
A typical installation height of approximately 5' (1.5
meters) is considered in these measurements.
The below illustrates the resolution.

Deployment
Placement of the room controller must be given
consideration. It is recommended to install the room
controller as close to a door as possible (but not so
as to be blocked by the door), or in an area with high
occupant movement.
Ideally the room controller should be installed 5'
above the floor surface to ensure maximum detection
range is achieved. As well, room controller placement
should ensure the occupant crosses the lens beam in
a perpendicular path within the prescribed detection
zone.
Example of Recommended Deployment
The illustration below shows room controllers installed
in ideal locations for two rooms.
The examination room shows one room controller
installed adjacent to the door. In this area of the room,
occupant traffic is high and ensures the occupant will
almost always cross the PIR detection path laterally
and within the detection range.
The waiting room shows one room controller installed
beside a door in the middle of the room. As shown
in the illustration, occupant traffic is high in several
areas of the room including the entrance, waiting room,
access to the door and activity around the reception
desk. Moreover, for each case aforementioned,
occupant movement almost always moves lateral to the
PIR, which ensures detection by the PIR, as well as
respecting the PIR detection range.
Recommended Installation
Examination Room
Waiting Room

Manual 2100-680
Page 14 of 18
Example of Non-Recommended Deployment
The illustration below shows four room controllers (two
for each room) installed in non-ideal locations for the
two rooms.
The examination room shows one room controller
installed in a low traffic area near the door, and a
second room controller installed on the wall directly
opposite the door. For the room controller installed
in the corner wall, the PIR could be blocked by the
opened door, while occupant traffic could also be
minimal in this area of the room. For the second room
controller installed opposite the door, the PIR detection
could fall outside the specified detection zone, while
at the same time most occupant movement would not
be lateral to the PIR, thereby not respecting optimal
crossing patterns for PIR detection.
Non-Recommended Installation
The waiting room shows one room controller installed
in the corner of the room, and a second room controller
installed beside the reception area. For the room
controller installed in the corner, the opening/closing of
the door creates high probability that the PIR would get
blocked, and therefore, occupancy going undetected.
For the room controller installed beside the reception
area, occupant traffic could fall outside the detection
zone, and the receptionist would often be below the
5' recommended installation height for the room
controller.

Wireless ZigBee Pro Motion Sensors
BrightStat controllers with ZigBee Pro wireless sensors
can be used in stand-alone mode, or with integration
to a central management system, to allow for advanced
functions such as central reservation and occupancy
functions.
Up to 10 different ZigBee motion sensors can be used
with a BrightStat room controller.
No tools are required for commissioning or servicing
the ZigBee devices. A simple interface on the devices
with an on-board LED and hidden switch provides all
required functions for local interaction. The controller
user interface has screens used to pair and configure
ZigBee devices (see below). Local information for
battery life and connectivity (heartbeat) are also
displayed through the ZigBee Pro wireless network.
