Y8150 Fresh Air Ventilation System,
W8150 Fresh Air Ventilation Control
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.
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.
IMPORTANT
Please read these instructions and keep them in
your records.

Y8150 FRESH AIR VENTILATION SYSTEM, W8150 FRESH AIR VENTILATION CONTROL
68-0282—11 4
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.
16 REMOTE Remote switch (two
terminals)
24 Vac powered contacts allow a remote switch closure to call for
ventilation.
17 AUX Auxiliary (two terminals) 24 Vac dry contacts allow W8150 to control an auxiliary device, such as
exhaust fan or HRV/ERV, with a call for ventilation.
18 DAMPER Damper (two terminals) 24 Vac powered contacts control fresh air damper.
19 XFMR C 24 Vac ventilation

568-0282—11
Installing fresh air damper, ducting,
and control…
1. Disconnect power from HVAC system.
2. Install the weather hood, ducting, and damper fol-
lowing local practices. Be sure all duct and insula-
tion 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 EARD6TZ end stops can be used to reduce the
amount of airflow in the duct. To prevent complete
opening, move the red tab to the desired range stop
location.
Wiring the control…
CAUTION
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 air-
flow.
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.
*In Canada, interlocking exhaust equip-
ment may be required for balanced
ventilation.
Ventilation Limit
This setting determines the maximum amount of time that
the fan runs for ventilation.

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: Resideo
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.
