Getting Started
• Review these instructions before beginning.
• Conrm that appropriate eld wiring is installed (standard
six-conductor room sensor cables, plenum or non-plenum
as required) within the maximum wiring run length
for the individual equipment controller. The maximum
recommended length is 100 feet (30 m).
• All wiring must comply with National Electric Code (NEC)
and local regulations.
Description
These room sensors allow users to view and adjust points in
the controller using the room sensor buttons and digital display.
Application
They work with McQuay BACnet VAV Actuator 2508021 and
2508021P10. These devices incorporate a solid state or 10K
NTC sensing element to detect temperature. The effective
sensing and setpoint range is 55 to 95°F (13 to 35°C). These
room sensors can be mounted on electrical boxes, stud-type
mounting brackets, or drywall. Obtain the necessary mounting
hardware and follow the appropriate mounting procedures for
the type of installation required.

InstallatIon
InstallatIon
The following section describes how to eld install a new
BACnet VAV Actuator Room Sensor. Expected Install Time:
20 minutes
CAUTION
Electrostatic discharge hazard. Can cause equipment
damage.
This equipment contains sensitive electronic components that
may be damaged by electrostatic discharge from your hands.
Before you handle a communications module, you need to
touch a grounded object, such as the metal enclosure, in
order to discharge the electrostatic potential in your body.
Required Tools and Materials
• Phillips sizes 1 and 2 screwdrivers
• Small and medium at-blade screwdrivers
• 1/16-inch hex key
• Medium-duty electric drill
• 3/16-inch (4.8 mm) drill bit
• One-inch (25 mm) hole saw
• Small level
• Tape measure
• Marker or pencil
If using non-terminated or damaged cables, you also need:
• Room sensor connector tool (RJ-11 crimping tool)
• Room sensor connector kit (P/N 2508046)
Installing a new BACnet VAV Actuator
Room Sensor
Mounting Information
Always mount the room sensor vertically, on a at wall.
Locate the room sensor:
• According to design specications and local regulations.
• Where the air circulates around it freely (not in recessed
areas or behind doors).
• Allowing a minimum of 4 inches (10 cm) free space above
and below for proper airow, the hex bit or passkey tool,
and the computer communication cable.
• Away from drafts caused by doors, windows, outside
walls, air registers, pipes, return air plenums, etc.
• Away from heat sources such as strong lights, replaces,
direct sunlight, etc.
• On an inside wall (preferably), about 5 feet (1.5 m)
above the nished oor or per code (ANSI, ADA, or local
regulation).
Drywall Mounting (No Rough-in), Typical
WARNING
For retrots: Before cutting the cable, make sure it is
disconnected from the Temperature Room Sensor port on the
controller cable end.
1. Mark the center (cable) hole and the mounting hole
locations, using the room sensor base plate as a
template. See Figure 2.

2. Drill two 3/16-inch (4.8 mm) mounting holes and mount
the two plastic wall anchors ush to below the wall
surface for stable mounting of the device.
3. Cut a 1-inch (25 mm) center hole with a hole saw.
4. Pull about three inches (75 mm) of the cable through the
hole in the base plate.
5. Mount the room sensor base plate on the wall, noting the
“UP” arrow:
a. Install the two mounting screws provided, but do
not tighten.
b. Level the room sensor base plate for appearance.
c. Tighten the two mounting screws to the room
sensor base plate.
6. Do one of the following:
a. If the cable is terminated: Inspect the RJ-11
connector for damage.
b. If the cable is non-terminated or if the RJ-11 was
damaged: Cut the cable, leaving about three
inches (75 mm) on the room sensor side of the
drywall, and attach an RJ-11 connector with an RJ-
11 crimping tool. On the RJ-11 connectors, ensure
that pin Number 1 connects to the same wire at
each end of the cable. See Figure 3.
7. Plug the terminated cable into the RJ-11 connector on the
back of the room sensor’s printed circuit board (PCB).
8. Feed the extra cable back through the hole.
9. Snap the room sensor cover to the room sensor base
plate by rst hooking the room sensor front to the top
latches, and then rotating the cover downward until it
latches.
10. Loosen the safety set screw at the bottom of the base
one or two revolutions to lock the cover to the base.
Be careful not to loosen too far as the screws can be
completely removed from the base.
11. Connect the room sensor to the Temperature Room
Sensor port on the controller.
This installation is now complete.
Figure 3: Terminating the RJ-11 Connector
Electrical Box and Rough-in Mounting, Typical
CAUTION
Over-tightening may cause the room sensor base plate to
crack or bend.
1. If a locator is attached to the rough-in device, remove the
locator by removing the two screws and lightly rocking
the locator to pull it free.
2. Untie the twist tie and pull about three inches (75 mm) of
the room sensor cable through the hole in the base plate.
3. Mount the room sensor base plate on the wall, noting the
“UP” arrow:
a. Install the two room sensor mounting screws
provided, but do not tighten.
b. Level the room sensor base plate for appearance
only.
c. Tighten the two mounting screws to the room
sensor base plate.
4. Continue with Drywall Mounting (No Rough-in), Typical,
Steps 7 through 11.
This installation is now complete.
