• 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
antenna or transmitter.

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.
BrightStat Controller Models
Bard Part Number Description Part Number Found on Back of Controller
8403-081 With Humidity and Motion Sensors VT8650U5500B
8403-082 With Motion Sensor VT8600U5500B
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
Reference unit installation manual for 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.
Occupied Override Mode
System reverts to occupied mode for duration
determined by “ToccTime” parameter.
Options
• Wireless adapter modules for BACnet models are
available.
• Three (3) universal inputs can be used and
configured for advanced functionality as required
by the application.
NOTE: RC (5) and RH (7) must both be powered for
heating and cooling operation.

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.
TABLE 4
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.
