Introduction
Introduction
Unpacking
Open the package and remove the equipment and components. Make
sure that you have all the items described on the order form or packing
slip.
Description
The IAQPoint is an infrared CO2Carbon Dioxide gas monitor. The
device is available in wall mount or duct mount and with or without LCD
screen. The optional LCD provides a real-time display of current
readings, depending on which sensors are installed. The IAQPoint is
designed for indoor use only.
The IAQPoint also has 4-20 mA outputs that can be configured on-site
(through connectors located at the back of the unit).

Introduction
Installation Guidelines
Installation Guidelines
• Make sure to locate the monitor and sensing assembly(ies) in an
area easily accessible to a technician.
• Avoid any location where the monitor could be subject to vibrations.
• Avoid any location where temperature changes occur rapidly.
• Verify all the requirements and existing regulations which may
affect the choice of location.
• For Duct-type housing, installation is recommended on a straight
duct at least 3 meters (9 ft) from any air intake or outlet.

Introduction
Installation Instructions
Installation Instructions
Wall Mount Installation
The recommended installation height is 1.5 m (5 ft) from the floor for
CO2monitoring in offices or similar applications related to indoor air
quality.
For applications where health hazards are an issue, such as CO2
storage facilities, the recommended installation height is 30.5 cm (1 ft)
from the floor.
1. Mount the bracket to the electrical box
(using standard electrical screws), as
shown at right.
2. Connect wiring to terminal at back of unit.
3. Insert the tabs at the back of the IAQPoint
into the slots in the top of the mounting
bracket, as shown below.
4. Press the bottom of the IAQPoint into the
bottom of the mounting bracket, until it
clicks into place.
5. If necessary, install locking screws in the holes provided at the base
of unit.
Note: The installation heights recommended by Honeywell Analytics
represent general guidelines. Always confirm with local laws and
regulations before proceeding, as these take precedence over
manufacturer’s recommendations.

Introduction
Installation Instructions
Duct-mount Installation
The IAQPoint Indoor Air Quality Monitor can be duct-mounted. It will
operate most effectively when the air speed is between 500-4,000 ft/
min (2.5-20.3 m/sec)1. It may be installed to monitor either incoming
fresh air or outgoing exhaust air. In order to optimize its operation,
install the monitor on a straight section of duct 3 feet (1 m) away from
any curved ductwork.
Sampling Probe Assembly
The sampling probe is supplied in 3 parts: the base (1 piece), the
sampling probe sections (11 pieces) and the plug (1 piece). Before use,
the sampling probe must be assembled by snapping together the base,
all 11 sampling probe sections, and the plug as shown in the illustration
below. (Two sampling probe sections are shown in the illustration.)
Before proceeding with the installation, verify that all sections have
been properly connected to create a solid sampling probe assembly.
1. Honeywell uses ft/min velocity rules but some industries and companies use cubic feet
per minute (CFM). To convert from CFM to velocity (ft/min), divide the flow by the area.
For example, in a 2 ft. x 4 ft. duct, where the area is 8 sq. ft., with an air flow of 30,000
CFM, the air velocity would be (30,000 cu. ft/min) ÷ (8 sq.ft) = 3,750 ft/min.

Introduction
Installation Instructions
Installation
1. Drill a 13/16 in. (3 cm) opening for the sampling tube.
2. Orient the lateral air holes to face the air flow and insert the
sampling tube into the opening.
3. Affix the octagonal plate to the duct.
4. Place a standard electrical box on the octagonal plate (orient the
box’s mounting holes vertically) and affix with two #8 metal screws.
5. Screw the mounting plate onto the electrical box.
6. Connect the wire from the electrical box to the IAQPoint monitor.
7. Connect the power and outputs as shown in Wiring Details.
8. Verify that the sampling tube feeds into the appropriate port on the
back of the IAQPoint monitor. Press the monitor onto the plastic
base (the latches will click).
The IAQPoint with the temperature and humidity sensor
option must be duct mounted using a different method. See

Introduction
Installation Instructions
Special Duct-mount Installation
The IAQPoint must be duct mounted using a special box if it is
equipped with the temperature and humidity sensor “antenna”. All of
the components housed within the box are factory assembled.
1. Select the location for the unit
2. Measure and mark the holes for intake and exhaust tubes
3. Drill the holes for the sampling tubes.
4. Affix intake and exhaust tubes to mounting box
5. Insert the tubes into the holes in conduit, orienting the air holes on
the air intake tube to face the airflow.
6. Screw the mounting box onto the conduit.
7. Remove the desired knock out (depending on where cables will
enter box) and affix appropriate conduit.
8. Remove the IAQPoint from the mounting plate to access
connection terminals
9. Run wiring through conduit and electrical box to unit and connect
wires according to Wiring Details
10. Press the IAQPoint onto the plastic base (latches will click), making
certain that sampling tube feeds into the appropriate port on the
back of the IAQPoint.

Electrical Wiring
Electrical and communication wiring is achieved through terminals
located at the back of the unit. Jumpers at the back of the unit allow
users to configure the detection range and the 4-20 output range.

Wiring Details
Available 4-20 mA Configurations
Available 4-20 mA Configurations
The back of the unit provides 4-20 terminals for CO2, temperature and
humidity (optional) and one jumper that allows users to set the output
range.
The 4-20 outputs are used to send a signal to a control or monitoring
unit. The strength of the signal is commensurate to the reading value:
A 4 mA signal represents the lowest value of the range.
A 20 mA signal represents the highest value of the range.
Terminal J1
Terminal J1 is reserved for power connections and for the CO24-20
output.
Terminal J2
Terminal J2 is used to connect the optional Temperature and Humidity
4-20 outputs.
Jumper JP5
Users whose control systems operate on voltage (rather than mA), may
wish to convert readings from mA to Volts using a resistor.
Jumper JP5 lets users configure the outputs for 0-20 mA, which can
then be converted to volts readings when used with either a 250 Ohm
(for 5 V) or 500 Ohm (for 10V) resistance.
If the there is a fault on the 4-20, the unit will send a 2 mA
signal. Note that if the output is set to 0-20 mA, a reading of 0
mA indicates either the presence of Nitrogen or a fault.
