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.

IMPORTANT

Please read these instructions and keep them in your
records.

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.
