• 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

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.
