Honeywell IAQPoint2 Quick Start Manual

IAQPoint2 Gas Monitor - Quick Start Guide
Introduction
The IAQPoint2 indoor air quality monitor features a simple-to-use,
customizable touchscreen display along with triple monitoring of
indoor air quality parameters (carbon dioxide or volatile organic
compounds, plus temperature and humidity) and demand-
controlled ventilation. The IAQPoint2 monitor increases energy
efficiency in commercial buildings by triggering fan activation as a
standalone solution or via a building automation system.
Installation kits: Tools needed:
• IAQPoint2 monitor • drill
• backplate • hole saw
• two plastic anchors w/metal • drill bit
screws (wall-mount only)
• hole saw (duct-mount only)
• two metal screws (duct-mount
• #1, #2 Phillips, 1/8 inch
only)
(3 mm) screwdrivers
• Resource CD
• wire strippers
• Quick Start Guide
• 5/32 inch Allen wrench
(wall-mount only)
More detailed instructions can be found on the Resource CD.

Wall mounting

Install the monitor in an area easily accessible by a technician.
Avoid locations in which it will be subjected to vibration or
rapid temperature fluctuations. Follow local regulations and site
requirements. Position duct-mounted monitors at least 10 feet (3
meters) from any air intakes or outlets.
The monitor can be mounted onto a wall by following this
procedure. (Monitors can also be mounted to standard junction
boxes). Monitors with the optional temperature sensor must be
mounted in a location with relatively still air.
Procedure:
1. Center the mounting plate over the wires from the wall with
the mounting holes.
2. With a pencil, mark the locations for the two mounting holes.
Typical mounting hole distances are shown in this illustration.

3. Drill a hole in the wall at each of the marks.
4. Insert a plastic anchor into each of the holes until they are
flush with the wall.
5. Thread the wires through the back of the backplate.
6. Attach the backplate to the wall by screwing the supplied
metal screws into the plastic anchors. Torque installation
screws to 11 in-oz (79 Nmm).
7. Connect each of the wires to the corresponding terminals
on the backplate, as shown in Figure 2. Wire digital models
as indicated on the label. Note that the meaning of the A
and B symbols for EIA/RS-485 wiring varies among vendors.
Terminal 6 corresponds to BACnet "+", the Modbus "D1",
and the EIA/RS-485 "B". Terminal 5 corresponds to BACnet
"-", the Modbus "D0", and EIA/RS-485 "A".
8. Set the slide switches according to the configuration of the
monitor.
9. Align the bottom of the bezel with the mounted assembly
and rotate the top into place. Press firmly until it snaps.
10. Torque the case hex screws to 7-10 oz-in (0.59-0.85 Nm).

Duct mounting

The monitor can be mounted on a rectangular duct at least 7 in.
× 7 in. (18 cm × 18 cm) or a round duct at least 24 inches (61 cm)
in diameter by two sheet metal screws which are supplied in the
installer's kit. Do not mount the monitor on the top or bottom of
a duct (the sampling tube is designed for horizontal installation).
Procedure:
1. Make a 1 1 / 16 -inch (27 mm) hole in the duct at the desired
sampling location.
2. Position the duct-mount bracket over the hole.
3. With a pencil, mark the locations for the two mounting holes.
4. Drill a hole in the duct at each of the marks.
5. Attach the mounting plate to the duct with the supplied sheet
metal screws. Torque the screws to 11 in-oz (79 Nmm).
6. Slide the sampling tube through the mounting bracket up to
the collar (shown in the following illustration).
7. Torque the case hex screws to screws to 7-10 oz-in (0.59-
0.85 Nm).

8. Rotate the sampling tube until the divider shown in the cross-
section illustration above is perpendicular to the flow of air in
the duct.
9. Lightly lubricate the connector O-ring with water to facilitate
installation.
10. Position the connector on the back of the monitor on the
sampling tube connector and twist a quarter-turn counter-
clockwise. A tight fit is normal (the O-ring on the sampling
tube provides a snug seal with the monitor). The monitor
will snap into position when it is securely attached to the
sampling tube. (The monitor can be rotated to any of four
positons.)
11. Tighten the mounting plate clamp screws.
12. Conduit is attached to the bottom of the monitor in the same
manner as standard electrical junction boxes.
First power-up
No calibration of the CO
The monitor will immediately begin operation with the default
parameters mentioned in the Menus section. If desired, the
monitor can be calibrated, however. Refer to the Technical Manual
for calibration procedures.

The monitor will accept two passwords. A level-one password
(0000 by default) will allow the user to, for example, modify the
monitor's temperature setpoints. A level-two password (2967 by
default) would give the user access to additional functions such
