Y8150 Fresh Air Ventilation System,
W8150 Fresh Air Ventilation Control
PRODUCT DATA
FEATURES
• Designed to help meet local ventilation codes and
standards, including ASHRAE 62.2-2010 standard,
“Ventilation and Acceptable Indoor Air Quality in
Low-Rise Residential Buildings.”
• Microcontroller optimizes the air delivery schedule to
make efficient use of normal HVAC run times.
• Easy-to-use input dials allow customized ventilation
for each installation.
• Test mode that includes immediate feedback to
installer to confirm that air delivery requirements of
selected ventilation standard are being met.
• Economical supply-only ventilation; works with forced
air system.
• Can be used with other equipment, such as an HRV/
ERV, for balanced ventilation.
APPLICATION
The Y8150 Fresh Air Ventilation System, W8150 Fresh Air
Ventilation Control provide fresh air to a home. The control
operates a fresh air intake damper and, when necessary,
activates the main HVAC blower to efficiently meet ASHRAE
ventilation rates.

INSTALLATION
A fresh air duct and damper must be installed between the
outdoors and the return side of the HVAC equipment. The
W8150 control will be mounted near the HVAC system and
wired between the thermostat and the fan control.
You will need…
• W8150 Fresh Air Ventilation Control.
• damper.
• transformer.
• insulated ductwork.
• outdoor weather hood.
• starting collar.
• access to 120 Vac power.
• airflow measuring tool.
TIPS:
• To meet ASHRAE 62.2-2010, system must have at least a
MERV 6 filter installed.
• In cold climates, balanced ventilation is recommended. An
exhaust fan or heat recovery ventilator can be used.
• Humid climates may require additional dehumidification
equipment.
Choosing a location…
When choosing locations for equipment, duct connections,
and fresh air intake, be sure to consult local code
requirements.
Device
Number Component Location
1 Fresh air intake Install away from known sources
of pollutants such as auto
exhaust, dryer vent exhaust or
chimney smoke.
2 Fresh air duct Install between weather hood and
upstream of equipment filter and
downstream of any duct-mounted
sensor.
3 Damper Install damper in fresh air duct,
where convenient. Optionally,
install heat recovery ventilator.
4 Control Locate the control for convenient
access and for easy wire routing.
5 Transformer Locate where convenient for line
voltage connection.
6 Filter Locate filter downstream of fresh
air intake.

Y8150 FRESH AIR VENTILATION SYSTEM, W8150 FRESH AIR VENTILATION CONTROL
CAUTION
Installing fresh air damper, ducting,
and control…
1. Disconnect power from HVAC system.
2. Install the weather hood, ducting, and damper following
local practices. Be sure all duct and insulation seams
are tightly sealed.
3. Mount the transformer and control.
TIPS:
• In general, larger ducting allows higher airflow, minimizes
additional fan run time and may be needed for larger
homes.
• Installing a damper directly to the return duct may be
convenient to support the damper and reduce ducting.
• Fresh air connection should be downstream of sensors
(such as a humidistat) in return air plenum.
• The EARD6 end stops can be used to reduce the amount
of airflow in the duct. To prevent complete opening, loosen
(but do not remove) the wing nut and move the upper lever
until the desired position is reached. Tighten the wing nut.
Keep the lower lever in the position shown.
Wiring the control…
Electrical Hazard.
Can cause personal injury or equipment damage.
Disconnect power to all systems before beginning
installation.
1. Wire the control. See wiring diagrams in Fig. 1-10 as
listed below. All wiring must comply with local codes,
ordinances, and regulations.
2. Reapply power to system and control.
TIP:
• Control package allows wire routing through side slots and
bottom openings.

Measuring airflow…
1. Make sure all HVAC system air filters are clean and
installed.
2. Push Test button:
• Control opens damper and turns on HVAC fan for
three minutes.
• A red or green light is flashing; you can now measure
airflow.
3. Follow instrument instructions for measuring airflow.
TIPS:
• You can exit the test mode at any time by pressing the test
button again.
• See Conversion Table (located after wiring diagrams) for
quick area and airflow setting conversions.
• For future reference, record the air flow on the inside of the
device cover.
• Pitot Tubes and flow measuring stations are commonly
used airflow measuring devices.
About the control settings…
Dial Settings
These settings allow the installer to customize the control to
meet the ventilation requirements for the home.
Ventilation Standard
Building codes are different everywhere. The W8150
Ventilation Control can be configured to operate based on:
• ASHRAE 62.2.
• ASHRAE 62-1999
TIP:
• Clear understanding of local codes and practices is
required to make sure the ventilation system is installed
and configured correctly. Generally, ASHRAE 62.2 control
method is recommended and can meet many existing local
codes.

Setting the control...
1. Be sure power is turned on.
2. Set the Ventilation Standard on the control.
3. Set the bedrooms dial.
4. Set the area (sq ft) dial.
5. Set the airflow (cfm) dial.
6. Press the test button and observe the lights:
Green light is flashing.
The dial settings meet the chosen standard.
Red light is flashing.
There is not enough fresh air delivered to meet the
requirements of the selected standard. See
Troubleshooting section.
7. Record settings on the label inside the cover as shown
in the diagram.
TIPS:
• Ventilation control reads new dial setting only when test
button is pushed or power is cycled. To ensure dial settings
are read, push test button after any changes are made.
• For single bedroom homes, set the bedrooms dial to 2 (this
may result in more ventilation than the minimum required).
• For homes having more than five bedrooms and only a
single ventilation system, set the bedrooms dial to 5 (this
may result in less ventilation than the minimum required).
• For conditioned square feet, set area (sq ft) dial to the
nearest value.
• For airflow, set airflow (cfm) dial to the nearest value.
• Vaulted ceilings do not need to be considered when setting
this control.
• For homes with multiple systems: Honeywell recommends
a ventilation control and fresh air intake for each system.
Measure ventilation airflow for each system independently.
Refer to Multi-system Setup Example for further details.

Multi-System Setup Example
Total square feet and bedrooms should be proportionately
split between the ventilation controls based on sq ft served by
each system regardless of where the bedrooms are located.
Example: 5,000 sq ft, six bedrooms:
System 1:
• serves 3200 sq ft,
• two bedrooms.
• fresh air intake measured at 127 cfm.
System 2:
• serves 1800 sq ft,
• four bedrooms
• fresh air intake measured at 98 cfm.
Set W8150 for System 1:
• 3100 sq ft,
• four bedrooms
• 130 cfm.
