Complete the following steps to install a KMC
Conquest™ BAC-9000 Series VAV Controller-

Actuator. For controller specications, see the

data sheet at kmccontrols.com. For additional

information, see the KMC Conquest Controller

Application Guide.

SET DRIVE HUB (45/60°) ROTATION LIMIT

NOTE: Complete the steps in this section if

the VAV damper rotation limit is either

60 or 45 degrees.

NOTE: If the VAV damper rotates 90 degrees,

skip this section and go to Mount

Controller on page 2 instead.

NOTE: The drive hub and V-clamp will be

rotated in the same direction in Step 8.

2. Push and hold the gear disengagement
lever

on the side of the controller.

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

NOTE: Overtightening the screw can cause

compression in the case which may
interfere with the controller operation.

3. Rotate the drive hub and V-clamp

in the

same direction that opened the damper.

NOTE: Continue to rotate the drive hub and

V-clamp until they reach a stop.

MOUNT CONTROLLER

NOTE: Install the controller in a metal

enclosure for RF shielding and physical
protection.

NOTE: The controller can be installed on a

3/8–5/8 inch (9.5–16 mm) round or
3/8–7/16 inch (99.5–11 mm) square

damper shaft with a minimum length

of 2 inches (51 mm).

NOTE: The Ethernet patch cable should be a

maximum of 150 feet (45 meters).

CAUTION

On Conquest “E” models, do NOT
plug a cable meant for Ethernet
communications into the Room Sensor
port! The Room Sensor port powers a
NetSensor, and the supplied voltage
may damage an Ethernet switch or
router.

CONNECT SENSORS AND EQUIPMENT

NOTE: A digital STE-9000 Series NetSensor

can be used for conguring the

controller (see Congure/Program

the Controller on page 7). After the

controller has been congured, an

STE-6010, STE-6014, or STE-6017

analog sensor can be connected to the

controller in place of the NetSensor.

See the relevant installation guide for
additional details.

NOTE: See Sample (BAC-9001) Wiring on

page 8 for more information.

CAUTION

Do NOT connect 24 VAC to the analog
outputs (UO3–UO5 and GNDs)!

NOTE: Use 24 VAC (only) with triac outputs

(BO6–BO9 with SC).

NOTE: Wire sizes 12–24 AWG can be clamped

in each terminal.
