install, operate, and service the equipment as well as protection of the equipment
itself. To promote safety, we use hazard alert labeling in this manual. Follow
the associated guidelines to avoid hazards.

Danger

Danger represents the most severe hazard alert. Bodily harm or death will
occur if danger guidelines are not followed.

Warning

Warning represents hazards that could result in severe injury or death.

Caution

Caution indicates potential personal injury or equipment or property damage
if instructions are not followed.

Note

Notes provide additional information that is important.

SECTION 2

Installing the controller

This section provides important instructions and guidelines for
installing the BAC-8007 and BAC-8207 controllers. Carefully review
this information before installing the controller.

Installing the VAV controller includes the following topics that are covered in
this section.

In addition to the topics, see the section Dual-duct connections on page 24 for
connecting the controllers to a TSP-8000 actuator for dual-duct operation.

Setting the rotation limits

Setting the
rotation limits

KMC ControlsInstalling the controller

Before mounting the controller, set the rotation limits with the supplied stop
screw. Installing the stop screw limits the shaft rotation to either 45 or 60 degrees.

Caution

Before setting the rotation limits on the controller, refer to the damper position
specifications in the VAV control box to which the controller will be attached.
Setting rotation limits that do not match the VAV damper may result in
improper operation or equipment damage.

Illustration 2-1 Controller stop selections

To set the rotational limits:

1. Turn the controller over so you have access to the back.

2. Manually rotate the actuator fully clockwise as viewed from the back.

3. Remove the stop screw from its storage location and clean any debris from
the threads.

4. Insert the screw into the correct stop position hole.

5. Tighten the screw only until the head touches the plastic in the bottom of
the recess.

Mounting Mount the controller inside of a metal enclosure. To maintain RF emissions

specifications, use either shielded connecting cables or enclose all cables in
conduit.

Mount the controller directly over the damper shaft. A minimum shaft length of

2.0 inch (51 mm) is required.

Note

The controller is designed to directly mount to 3/8 to 5/8 inch (9.5 to 16mm)
round or 3/8 to 7/16 (9.5 to 11mm) square damper shafts.

BAC-8007 and BAC-8207 VAV Controllers Installing the controller

Mounting

Mount the controller close enough to the pitot tubes to keep the tubing length to
a minimum. In typical installations the controller’s inputs and sensors are within
24 inches of each other.

Mount the controller as follows:

1. Loosen the nuts on the U-bolt until the shaft can fit through the collar.

2. Place the controller on the damper shaft in the approximate final position.
Position the controller loosely against the mounting surface so that the
mounting bushing can float freely in the mounting tab.

3. Center the mounting bushing in the slot of the mounting tab and secure it
using a #8 self-tapping screw.

4. Manually position the damper in the full open position.

5. Adjust the drive hub as follows:
a. If the damper rotates counter clockwise to close, depress the gear

disengagement button and rotate the drive hub to the full clockwise
position then release the button.

b. If the damper rotates clockwise to close, depress the gear disengagement

button and rotate the drive hub to the full counter clockwise position
then release the button.

6. Lock the hub to the shaft by evenly tightening the V-bolt nuts to 30 to 35
in-lbs.

Connect them only to a BACnet MS/TP network.

See Application Note AN0404A, Planning BACnet Networks for additional
information about installing controllers.

S +B -A

Illustration 2-10 MS/TP network connection

Connections and wiring

Use the following principles when connecting a controller to an MS/TP
network:

Connect no more than 128 addressable BACnet devices to one MS/TP
network. The devices can be any mix of controllers or routers.
To prevent network traffic bottlenecks, limit the MS/TP network size to 60
controllers.
Use 18 gauge, twisted pair, shielded cable with capacitance of no more than
51 picofarads per foot for all network wiring. Belden cable model #82760
meets the cable requirements.
Connect the -A terminal in parallel with all other - terminals.
Connect the +B terminal in parallel with all other + terminals.
Connect the shields of the cable together at each controller. For KMC
BACnet controllers use the S terminal.
Connect the shield to an earth ground at one end only.
Use a KMD–5575 repeater between every 32 MS/TP devices or if the cable
length will exceed 4000 feet (1220 meters). Use no more than four repeaters
per MS/TP network.
Place a KMD–5567 surge surpressor in the cable where it exits a building.

The controllers require an external, 24 volt, AC power source. Use the following
guidelines when choosing and wiring transformers.

Use a Class-2 transformer of the appropriate size to supply power to
the controllers. Titus recommends powering only one controller from each
transformer.

Do not run 24 volt, AC power from within an enclosure to external
controllers.

SECTION 3

Setting up dual-duct controllers

The topics in this section cover setting up the BAC-8007 and
BAC-8207 for dual-duct VAV operation. These are advanced topics
for controls technicians and engineers.

The BAC-8007 and BAC-8207 dual-duct VAV controllers are set up by the
manufacturer to operate as soon as power is applied and connected as described
in the section Installing the controller

Setting up the dual-duct VAV controllers may include setting BACnet objects
with a BACnet Operator Workstation such as TotalControl. The objects may also
be set up with a STE-8001 or STE-8201. The following topics are covered in this
section.

Caution

Change only the present values of the objects listed in this section. Changing
any other objects or properties will result in improper operation.

Before connecting the controller to a BACnet MS/TP network, configure the
following network parameters with either a BACnet operator workstation or
temporarily connecting an STE-8001 or STE-8201 to the controller.

Device instance—Set from 0 to 4,194,302. A device instance number must
be unique across the BACnet internetwork.

Baud—Valid baud settings are 9600, 19200, 38400, and 76800.
MAC—Set from 0 to 127. Must be unique on the MS/TP network to which

the controller is connected.

Setting temperature setpoints

Setting
temperature
setpoints

The space temperate setpoints listed in Table 3-1, “Temperature setpoints,” on
page 26 are used to control the controller VAV operation. The temperature
setpoints have default values, but may be manipulated depending on which
type of wall sensor is connected to the controller.

Occupied cooling and heating setpoints These setpoints are user controlled
space setpoints that originate from an attached sensor. If no sensor is attached
the values for these setpoints are manually entered by a controls technician.

Unoccupied cooling and heating setpoints The unoccupied setpoints are
manually entered values to set the heating and cooling temperature when the
space is unoccupied.

Minimum cooling setpoint A manually entered value to limit the occupied
cooling setpoint regardless of the value entered by the user.

Maximum heating setpoint A manually entered value to limit the occupied
heating setpoint regardless of the value entered by the user.

Minimum setpoint differential Sets the minimum temperature separation
between occupied heating and cooling setpoints.

Standby differential This differential is added or subtracted from the occupied
temperature setpoints to calculate the standby setpoints.

SAT changeover temperature Sets the supply air temperature at which the
controller will change from heating to cooling. The changeover takes place when
the supply air temperature is 2° above or below the discharge air temperature
setpoint.
